***Video Conferencing Hardware and You***

If you are new to the game there is some video conferencing hardware to consider.Gone are the days when you had to fly across the country and drain your company's expense account just to attend a two-hour meeting. Now, all you have to do is turn on your computer and you're ready to go.But if you are new to the world of video conferencing online, it may not be that easy. You might not have any idea of the different video conferencing hardware components that you will need to get started. To make things even more difficult, a quick Internet search for the phrase "video conferencing camera" brings up more than 42,000 entries. Yikes!In the interest of protecting your sanity and boosting your status in the eyes of your boss, we've provided a brief list of the basic pieces of equipment you'll need to get conferencing and good places to buy them:Personal ComputerMost offices these days are equipped with personal computers (PC). These temperamental creatures are a necessary evil to keep your business organized and competitive in the twenty-first century market. A PC is also completely essential to video conferencing, as your computer hooks up with other computers so that you can conduct your meetings online.ModemWhether DSL or dial-up, most offices these days are connected to the Internet. The web is a valuable tool in business today and almost everyone has a website - even your neighbor's dog. Internet connection is a must for online conferencing, as you actually have to be online for this type of conferencing. Dial-up services will work for video conferencing online, but your images will be less clear. ISDN connections work best as they provide the fastest connection speeds and clearest pictures.CameraA video conferencing camera is an important piece of hardware as it enables you to talk face to face to your colleague or customer across the country. Without them, you're just audio conferencing. Prices for video conferencing cameras range from a basic IBM model going for $40 to a snazzier PolyCom model that runs about $499. Logitech sells a model specially designed for laptops or notebooks.Cables and StuffYou will need a USB cable to convert the images that your camera records to a format that your computer can understand. USB Gear provides several different types of equipment that take up minimal space on your PC and will get the job done.MicrophoneUnless you want your video conference to become just a visual conference, some type of microphone is necessary for each participant to communicate with the others. Wideband Solutions sells different microphones designed to cover both small and large boardrooms. If you just need a microphone to cover you and your desk, Phoniex Audio sells a microphone that will do the job.HeadsetWhile not completely necessary, a headset is a convenient piece of equipment for any savvy video conferencer. Imagine trying to crunch some numbers on a spreadsheet and carry on a conversation about your budget with a phone awkwardly cradled in the crook of your shoulder, while your boss looks on from 300 miles away. Not exactly the put-together professional image you want to convey.Time to Shop!Ebay and Amazon are good spots to go for used equipment, but buyer beware - you never know what condition it might reach you in. Always be sure to use reputable sellers with good customer ratings. PolyCom is well known in the industry and sells top-of-the line equipment. You can also try NexTag. This site that provides a search of the best prices on whatever electronic equipment you specify.Mark Walters manages http: / / www.VideoConferencingStar.com and suggest you learn how to choose a Internet Webcam here.

***3 Ways Computers Can Hurt Your Ministry - Part 1 - Ineffective unimarter UniMarter
***3 Ways Computers Can Hurt Your Ministry - Part 1 - Ineffective Data Backups***

Our computers have become almost indispensable ministry tools. What would you do if the worst happened and you had to function without your computers? Would your ministry survive?This article is the first in a 3-part series on how to protect your ministry from serious computer-related loss. This time we?re going to focus on protecting your critical data with effective backups. In the next two installments, we?ll cover the basics of network security and finally what you should know about software license compliance.Ineffective data backups really do have the potential to hurt your ministry. Here are some frightening statistics:31% of PC users have lost all of their files due to events beyond their control.60% of companies that lose their data will shut down within 6 months of the disaster.Armed with the right knowledge, you can protect yourself and avoid becoming another statistic.Back Up Your Data!Most people would agree that computer data is one of their most valuable organizational assets. What would you do if all your donor and accounting files were suddenly gone forever because a hard drive on your server crashed? This could also happen through disgruntled employees, accidental deletion, corruption in one of your software programs or even because of an attack from an outside hacker. The first line of defense in protecting your ministry data is to perform regular backups.What exactly is a backup? It?s when you make a copy of your important data and keep it in a safe place, so you can restore that data if it ever becomes necessary later. The most common method of backing up data is to use a tape drive and backup tapes. I?ll have some important recommendations for you later in this article, but the critical thing to understand is that you MUST do something?any kind of data backup is better than none at all. If you ignore your data, it just might go away!Back to the FutureRemember the 1985 movie ?Back to the Future?? Just like the character in that film used a sports car to travel back in time, you can take your ministry back in time, too. Instead of keeping just one backup copy of your data, you should set up a system that keeps copies of your data for set time intervals (every day, every week, every month, every quarter, every year, etc.). Use a different tape or disk for each backup you make and then label them by date, and you will soon have a library of archived data backups you can restore from as needed.Why go through all that trouble? Well, suppose you find out that a very important Excel spreadsheet is now corrupted and you can?t open it. You haven?t used it for several months, and your backup strategy has been to keep writing over the same tapes every week. Chances are all the backups of that Excel file are probably corrupted, too! But what if you would?ve used a different strategy and kept an archive of your backups for each month of the previous year? You could then easily go back in time to the month when you knew the Excel file was still working and restore that copy?the issue would be quickly & easily resolved. Time travel can be pretty useful sometimes!How to Make Effective Data BackupsIf you have multiple computers networked in your office, keeping all your data in a single location (like a file server) and backing that up every night is the recommended way to perform backups. I would also recommend using a 20-tape rotation, which gives you the ability to ?go back in time? up to a whole year (in various intervals) to restore important files.You should also keep the most recent copy of your backup off-site (i.e., at another location away from your office). This is critical because if your building burned to the ground, your data backups would be destroyed right along with it. With a recent off-site copy, you could restore what you need on new equipment and get back to the business of ministry quickly.I recommend using enterprise-quality backup software to perform your data backups. Good software, like Veritas Backup Exec and Computer Associates BrightStor ArcServe will schedule everything for you, run automatically and keep logs of everything that does and doesn?t get backed up. These programs can also notify you by email (or some other method) when a backup is finished, if it was successful and whether or not you need to address anything. Aside from a little ongoing monitoring, everything can be automated. All you have to do is remember to change tapes every day.If you?re a home office or small office user without the resources to do tape backups, a ZIP drive, an external hard drive, a CD / DVD burner or even one of those cool little USB jump drives that fit on a key ring would all be options to consider. There are also services that let you do online backups over the Internet for a monthly fee. These are good options, as long as the amount of data isn?t too large. Some services you can check into include Remote Data Backups, U.S. Data Trust's LiveVault Online Backup Service and iBackup.Another Form of InsuranceBackups are really like another form of insurance. What kind of problems would you have if your ministry data was wiped out? Could it be replaced at any price? With a relatively small initial investment in equipment and some ongoing monitoring and maintenance, you can practically guarantee that your critical data will be available when you need it.Protecting your data by effective backups is only part of the solution. Next time we?ll talk about some simple steps you can take to protect your network against hackers, viruses, disgruntled employees and other potential vulnerabilities.Donnie Schexnayder is a ministry technology expert.

***Will Your Computer Be Windows Vista Capable?*** Microsoft unimarter UniMarter
***Will Your Computer Be Windows Vista Capable?***

Microsoft's new operating system, Vista, which is due to go on widespread release in early 2007 will make huge demands of your computer's graphics capabilities.The term 'Aero Glass' may not mean much to a lot of you at the moment but it is the name that defines the new (less violent) world of graphics.It is the 3D front end for Windows Vista, Microsoft's new operating system, which is due next year.This allows the windows to be transparent and you can move them around in a 3D environment.However, the not so good news is that not everyone will have a PC that will be compatible.A lot of people buy PCs that do not have a separate and discrete graphics card. They have something called integrated graphics, which is basically built into their motherboard and controlled by the main processor via a small chip.Typically today you may buy an Intel PC that has graphics built in, or 'on board' as it's often called. That's where the questionable part may be - it may or may not work with Aero Glass, most likely not.Windows Vista turns up the graphic environment a few notches and as a result, demands much more of your computer's resources.A Windows Vista Capable PC to run only the basic version of Vista must include at least:

A modern processor (at least 800MHz)
512 MB of system memory
A graphics processor that is DirectX 9 capable
To be able to run Windows Vista Premium, your computer will need at least:

1 GHz 32-bit (x86) or 64-bit (x64) processor
1 GB of system memory
A graphics processor that runs Windows Aero
128 MB of graphics memory
40 GB of hard drive capacity with 15 GB free space
Audio output capability
Internet access capability
Should you wish to watch TV you will need a minimum of 1Gb of system memory to run Windows Media Center, not to mention a compatible tuner card.So what versions of Windows Vista will be available?

Windows Vista Business - for small to medium (SME) business users
Windows Vista Home Basic - the minimum Vista spec for basic users
Windows Vista Home Premium - the more advanced and new featured Vista
Windows Vista Ultimate - the best of business and home entertainment features
Does your computer currently have the basic requirements for Vista?
Luckily, Microsoft has a useful little gizmo, called the Windows Vista Upgrade Advisor (beta), that you can download to scan your system and tell you what version of Vista your system is capable of handling (if any).One thing is for sure - the PC is about to get as much of a major overhaul as the Windows operating system.J Fox is a webmaster running a number of sites including those outlining broadband providers in the uk.

***Third-Party Hardware Maintenance vs Manufacturer's Warranty: W unimarter UniMarter
***Third-Party Hardware Maintenance vs Manufacturer's Warranty: What's Best For Your Business?***

When purchasing computer hardware for your business, system availability is a major consideration. While you hope it will remain reliable, you need to manage the risk that at some time a critical system component will fail, calling for hardware maintenance.Such failures often result in the system being unavailable to users until repaired. This ?system down-time? can be very costly when users sit idle and unproductive.Many assume that the standard manufacturer?s warranty will adequately protect them. But the ?small print? of standard warranties can result in less than satisfactory hardware maintenance results for businesses. Even expensive warranty uplifts may not deliver adequate protection against these costs.Response TimesOne of your systems fails, so you call the warranty-provider?s telephone hotline and speak to an operator in a call centre -- perhaps overseas -- who simply takes a message.If the failed system is under a ?next business day? telephone response arrangement for hardware maintenance, then your staff could be unable to do their job for a day or more before the warranty provider even gets around to diagnosing the problem. And with a ?best effort? onsite response, it could be several days before a hardware maintenance engineer arrives.If the system loss has company-wide impact then the implications are even more serious. Standard warranties only cover you for hardware maintenance during working hours -- so a failure on a Friday afternoon could leave your business crippled well into the following Monday.Businesses that can?t afford this sort of downtime should look to specialist third party hardware maintenance providers that maximise system availability by tailoring support arrangements to meet your specific business needs.Look for hardware maintenance service providers who offer short, defined response times -- such as a guarantee of a response to your call within ten minutes from a trained hardware maintenance engineer who will solve your issue, and on-site response within two hours for critical system failures.Also look for organisations who will assign a hardware maintenance engineer permanently to your account. This ensures that they become familiar with your IT environment and personnel -- a factor crucial to ensuring speedy response and resolution of critical system failures.Parts HoldingsHardware maintenance response times are irrelevant if you then have to wait for parts to be shipped from interstate or overseas. Equipment manufacturers generally hold replacement components for warranty service in a single location nationally. As a result, you may be waiting for 24 to 48 hours while the part you need is shipped, delivered and installed.A hardware maintenance provider which is focussed on maximising system uptime holds spares locally to shorten delivery times. Ask potential service providers for an explanation of their parts holding strategies and methodologies. Find out what ratio of spares are held against systems under contract and whether these parts are regularly tested. With sufficient local spares, hardware maintenance engineers can attend site with the appropriate part in hand to further speed the repair process.Beyond Hardware ?Break-Fix?A standard warranty will only cover you for the repair of your system, including the delivery and installation of replacement parts, and provides no guarantees as to when your hardware maintenance issue will be resolved.A hardware maintenance service tailored to maximise systems availability, however, offers a lot more, including:taking ownership of the ?grey? areas -- such as operating system issues and other causes of hardware problems
a first-call fix rate of over 95% -- which means you won?t have to wait for multiple engineer visits before system functionality is restoredThese superior service levels meet the operational needs of businesses which are dependent on system availability. Ask potential hardware maintenance providers for customer testimonials and references to substantiate their service levels.So, is a standard manufacturer?s warranty really good enough for your business? A standard warranty service might be ?free?, but having staff unable to work -- or customers able to contact you -- could end up costing your business heavily in the long run. Even expensive warranty uplifts do not completely mitigate the risks.The good news is that specialised and highly-focused third-party hardware maintenance solutions are available to solve this problem.Your hardware maintenance agreement can be tailored to meet your specific operational needs and risk management strategy. Paid on a monthly basis, they offer you better cash flow and operational flexibility -- for around the same as a manufacturer?s warranty uplift.But most importantly, they can reduce system downtime by many hours a year -- saving you many thousands in lost productivity and revenue.Clint is a Director of Interactive, a leading hardware maintenance & disaster recovery firm, servicing more than 850 corporations.

***Stopping Case Fan Vibration For Computers*** I will be di unimarter UniMarter
***Stopping Case Fan Vibration For Computers***

I will be discussing the three best solutions which I
always use myself to lower excessive vibrations of case
fans, and the ways anybody can lower their decibel levels.Most reports will tell you how vibrations work, and how
the noise is caused. This article is different, there isn't
any computer language here that isn't easily understood.Case fans mounted to your case will make the metal material
of your computer vibrate. If you've ever tried holding a
powered case fan, you'll know that it's almost silent.If you've seen any of my previous articles, you should know
that I like keeping my noise levels in my computer as low
as possible. A huge factor for unneeded noise are the case
fans. There are a few ways I will share which I use to
solve this problem.I have put together three of the most important techniques
which I use to cut down on my case fan noise.1.) Case Fan Silica Gel - Using Ultra-light silica gel will
create a slight barrier between your case fan and your
computers case. Doing this will cut down on some
vibrations.2.) Fan Speed - Reducing the speed of your case fan will
significantly decrease the amount of vibration. To do this,
you will need to purchase a fan controller. A fan
controller can be found in a computer store or an online
store for about $15 dollars.3.) Case metal thickening - You can reduce vibrations by
thickening your cases metal that your fans are mounted to.
The metal will be less flexible after doing this, and will
become more sturdy. This will stop noise from reverberating
throughout the case.By following all three of these solutions, a significant
drop in noise level for your case fans should be noticed.
There are however more strategies for making your fans
quieter if vibrations aren't your problem.Other techniques involve decreasing the amount of
turbulence made by the case fans. You can produce steady
airflow with the replacement of certain cables, moving your
fans, and taking off the grills of fans.Aaron Brandon is a contributing author. He is considered an

***Some Notes About Notebook Computers*** Are you interested unimarter UniMarter
***Some Notes About Notebook Computers***

Are you interested in laptops? Perhaps you are interested in buying one, or you already have one and just like to read more about them. Either way, I have some good information for you regarding laptops and their use. I really like laptops. I think besides executives, gamers, multimedia guys and the like that have their own dedicated purpose PCs, more and more people will have their own laptops as their primary and only computer.You see, they are very portable. How many times have you tried lugging your computer tower from location to location? If you have not tried this, you are not missing much. It's a pain to have to carry the bulky tower, then collect your monitor and then pick up your keyboard and mouse. With your laptop, you close the screen / lid, shove it into it's carry bag and away you go.They are also all-in-one. What this means is, all the components and peripherals you might buy for a standard PC such as the monitor, keyboard, mouse, speakers, microphone, camera, network card, modem, wireless adapter, etc are all built into the laptop case. This means nowhere near the amount of messy cables to connect everything. You may have an external mouse (which I highly recommend) and plug in the phone line or network cable for your internet, but beyond that, there is little else that you need to have. It's all in there. That saves cable mess and desktop space that might have otherwise been used up by other peripherals.As a side note however, despite the hype, they are not designed for speed. The processor (brain of the machine) may be fast, but there are so many other factors that come into play regarding how fast and responsive a machine is. So, if you are a keen gamer, a laptop might not be doing you many favours. It is certainly not going to be a bad purchase, but the built-in video accelerators still have a good long way to go before they match their desktop counterparts.A major concern is price. However, this is becoming less and less of an issue, as many laptops are now the same price if not cheaper than some particular desktop computers and laptop computer are outselling desktop computers in many, many places.One other note is compatibility. You wont be able to use standard off the shelf components in your machine, if you decide to perform some hardware maintenance yourself. Laptop components are generally pricier than their desktop equivalents, so keep that in mine. However, most USB and firewire devices should work out of the box if you wish to extend your laptop's capabilities that way.They are not the promised land of computing, but they have come a long way in portability, ease of use, speed and price. You certainly wont be making a bad decision buying one, and you should that they are really reliable little machines. Consider one next time you are thinking about upgrading. Maybe you could abuse their advantages for yourself?Martin is a technology consultant, programmer and author.

***Does a White Box Computer Make Sense for Your Business?*** unimarter UniMarter
***Does a White Box Computer Make Sense for Your Business?***

When your business needs new computers, you might want to look beyond the big names such as Dell, HP or Gateway and consider local vendors who assemble so-called white box computers from industry-standard parts.Of course you should take some precautions. Ask around about the local computer store, both among your friends and business partners and on local bulletin boards. Check whether any complaints have been lodged with the BBB. Decide on a configuration and get a written estimate, then compare that with the prices asked by the national vendors. Find out about store hours and exact warranty terms.Decide whether you can live without 24-hour phone supports (but then, is it so useful to talk to someone who just reads from a script, as opposed to waiting until the local store opens and you can call them or drop off your computer?)Here are some of the advantages of local computer sellers:1. They are are more likely to value you as a customer. After all, you may be 1 / 1000th of their annual sales, rather than 1 / 1000,000th of the sales of a big company.2. They are more flexible. Do you want an Intel or AMD processor? A particular motherboard? A hard drive by a specific manufacturer? They can provide that, while the major brands often restrict your options.3. They have a low overhead. While large companies can buy components more cheaply, they also spend millions on advertising.
The local store can often compete on price, particularly when you upgrade the configuration offered by the big brands to something that is actually usable.4. They use standard parts. Some of the big names in computers use proprietary parts, such as power supplies, that cannot be replaced with industry-standard parts. With a local computer store, you can specifiy exactly what you want to get.5. They don't pre-load your computer with useless software. All the trial and demo version of AOL and other programs can really clutter your computer. If your local store installs Windows, that is all that will be on your computer.The major drawback is that your local computer store might go out of business. I had that happen with a store that had been around for over 10 years, but the computers I bought from them still work, and when they have to be fixed, any other local computer store can repair them.Pamela Bruce lives in Austin, TX.

***Computer Hardware***

Computer hardware means the physical part of a computer and it is totally different from computer software or computer programs and data that are used within hardware. The hardware of a computer is rarely changed as compared with software and data, which are readily shaped, modified or erased on the computer. Normal users do not see most computer hardware as it is enclosed as embedded systems in automobiles, microwave ovens, compact disc players and many other household appliances.A typical personal computer consists of a case in desktop and other different parts. Motherboard or system board with slots for expansion cards and holding parts including Central processing unit (CPU) , Random Access Memory (RAM) for program execution and short-term data storage. It also consists of PCI bus, PCI-E or AGP bus, ISA bus, USB and power supply that holds a transformer, voltage control and fan.The storage controllers of IDE, SATA, SCSI or other type, that control hard disk, floppy disk, CD-ROM and other drives. Video display controller that produces the output for the computer display Computer bus controllers to connect the computer to external peripheral devices such as printers or scanners.Some type of a removable media writer includes CD, CD-ROM Drive, CD Writer, DVD, DVD-ROM Drive, DVD Writer, DVD-RAM Drive, Floppy disk, Zip drive, USB Flash Drive, Tape drive - mainly for backup and long-term storage, Internal storage that keeps data inside the computer for later use. Hard disk is used for medium-term storage of data. Sound card translates signals from the system board into analog voltage levels and has terminals to plug in speakers. Networking is used to connect the computer to the Internet and / or other computers and modem for dial-up connections.In addition, hardware can include external components of a computer system. Mainly the computer input devices includes keyboard, pointing devices, mouse, trackball, gaming devices, joystick, gamepad image, video input devices, image scanner, web cam, audio input devices and microphone.
Output devices consist of printer, monitor, audio output devices, speakers and headset.The author presents the website on computer hardware.

***Design Your Own Commercial Product With Microchip dsPIC Microc unimarter UniMarter
***Design Your Own Commercial Product With Microchip dsPIC Microcontrollers***

Suppose you feel a burning desire one day to start building your own commercial product and become an employer yourself. Sooner or later you will experience this, and I want to help you finding the ?means? you need to implement your dreams into reality.In terms of hardware I suggest exploring dsPIC microcontrollers running at 120 MHz. They are the top products built by Microchip to date, and you cannot fail with those ones--trust me. Particular to Microchip products, they are the easiest to work with, and this is encouraging news to beginners. Do not be afraid of working with electronics. Today, almost all parts we use are modules, and all you have to do is put them together in the right way, almost like in a Lego game. Of course, in time, and with a lot of dedication, you could become an expert!For firmware you do not need to shop around too much, because you are going to find the right tool you need again at Microchip: the C30 ANSI C compiler. This is an excellent tool and it has a range of 22 dsPIC microcontrollers to date, but few tens new ones, more powerful, are going to be added in 2006 and 2007. The good news is you can try C30 before you buy it, and you have exactly 60 free working C30 days. This is a lot of good working time, and you need to use it at maximum. It is possible you are afraid of this firmware ?thing?. Don?t be. It can be as simple as sketching a story on paper, only a bit funnier, when you use C to write firmware.Well, it is the dsPIC processors we are talking about, particularly dsPIC30F4011, and you think, probably, it is very difficult to work with this one. Not so, my friend. In fact, this is the easiest option available in the entire World today. Learning hardware, firmware, and software design can be incredibly easy, beyond your wildest expectations, with the right tutorial book. You are going to discover that exceptional book I refer to in my home site. Have no fears my friend: the book is very easy to read, just like this article I present here.The true beauty is, the book comes with a Hardware Companion Kit (HCK). Fact is, this is a Practical Design Project and all firmware and software programs developed are thoroughly explained, and working. Of course, the companion kit is recommended for beginners in hardware, firmware, and software design. For advanced levels designers it is not mandatory to purchase the companion kit. Here is another interesting aspect: the level of the book is beginners, medium, and even advanced designers. The amount of useful, practical, working examples it presents it is tremendous!You do not need to be an expert to learn working with dsPIC microcontrollers. On the contrary, you could become a GURU in 60 days! All it takes is determination and little desire to learn. This is all! If you have what it takes than do it, my friend. Once you know the ?how-to? you take charge: discover you commercial product and build it. We live in a free market World and everybody is welcome!My advice is, look at the simplest things around you: a door, a window, a lamp, a bicycle, and so on. Think about adding useful intelligence to any of them. Our life is driven by hardware, firmware, and software today, but there are still thousands and thousands of unexplored avenues. If you keep on looking for them, you will discover your commercial product one day--I have no doubts about this.Take for instance something very blunt, even vulgar: a hammer. You can easily design a tiny hardware module to count how many times it struck per day during the past year, and how hard was each blow. Next, you can design your intelligent hammer to ?talk? to your PC and download the data it contains. This is not all, because once the hammer data is on PC it will be processed graphically, for statistical analysis, or for even more advanced analysis. Your ?intelligent? hammer may even access a site on the Internet by itself and exchange data there. Mind this please: I describe here the blunt ?Hammer Application?! For smarter ideas things may look way more interesting, and the book I mentioned teaches you everything you need to know to design intelligent control applications. Even more, you will discover in my home site few pages dedicated to basic electronics, and to many other exciting topics.Anyway, it will take some time until you discover your beneficial commercial product. Meanwhile, you can enhance your resume and your technical aptitudes. The more you learn, the better prepared you will be when the right time comes.O G POPA is Professional Engineer in BC, Canada.

Power surge are one of the most feared incident on electronic devices. Same as computer, they are really susceptible to power surges. Even though surges usually last only milliseconds (and are somewhat filtered by the transformer in the power supply), that high voltage can exceed the withstand voltage of the insulating layers inside the integrated circuit chips and burned everything inside your computer.The power delivered to your electronics devices and computer is stable and constant, in theory of course. In real life, it doesn?t work that way. Often power surge occurs when the normal flow of electricity is interrupted, and then started again, or there was an occurrence that something sends excess electrical energy into the system. Any number of events, from lightning strikes to power failures, can cause power surges. Even your own electrical devices and computer can cause them. Refrigerators and air conditioners, for example, have motors that turn on and off, diverting electricity to and from other appliances and producing low-level power surges. On computer, internal peripheral can cause small surges that can reduced your computer lifespan or even destroy it completely.On computer a switching power supply is designed to convert AC into various DC voltages. The internal transformers on power supply that do this, the capacitors to bridge over dips in the line power, all these are rated to handle a certain amount of energy at any given time. If you go outside of range of that certain amount, you overload the parts. Maybe marginal parts fail and die. Maybe they let through more energy than they should. In some cases, maybe things catch on fire. Like things you saw on fried chips due to extreme overclock. Cheaper Power Supply Units will be using cheaper components - the upshot of this is the components have weaker tolerances, and don't handle going outside their tolerances as gracefully.To prevent it you need a good UPS (Uninterruptible Power Supply) to protect your computer and another electronic appliance. However no UPS can withstand power of nature. Even a good UPS cannot tolerate extreme power of lighting. During storm or rain situation you might want to consider turn off you computer and unplug it. Also unplug phone lines and another line like coaxial cables that are being used for cable TV and broadband connection, since they are susceptible to lighting strike. Power surges caused by lighting are seldom to happen though there are possibilities.On computer you will face another problem. Internal surges that can?t be prevent from external UPS. This caused simply by turn it on and off your computer. So every time you turn on and off your computer, you actually decreased life span of your computer and adding possibility to destroy the component completely. And there is no way to avoid this matter for now. Since there is no data how it will affect your computer. I suggest that you scheduled your computer to be use as efficient as possible.--FADicky Satrio Sudiro is an author of blog Digital Binary.

***How to Buy an Assembled PC?***

Today PC is considered as the one of the most essential components of our daily life. We can?t imagine a single minute without the presence of a PC. From office to our home, everywhere it has a strong presence.But buying the right PC is not so easy as it sounds. One of the easier processes is buying a Branded PC. There are big names in this field. And they come with lucrative offers to stay ahead in the competitive market. But the buyer always has a dilemma. Which one is the best and cost effective? If one branded PC has one advantage, the other has one more advantage, so the best possible way is to build your own PC with all the advantages that you require. Knowledgeable persons, however, prefer buying an assembled PC, as it is cheaper in price and can be custom built.Here are few tips for buying an assembled PC:? Make a list of hardware that you require. This can be done by consulting with someone who has a solid knowledge.? Find out a shop that has market goodwill.? Ensure that all hardware parts have warranty. Some parts like hard disks nowadays come with five years warranty. So it is recommended to check carefully before installing the hardware in the PC.? Today most motherboards have on board graphic cards. But if you are a multimedia professional, you can fit an additional graphic card (AGP card).? The cabinet of the PC is an essential part. Because all main parts are to be stored there. Nowadays some very good ATX cabinets with powerful SMPS (Power supply), 3 fans and front USB ports can be found at cheap prices. 3-fan cabinet keeps the cabinet cool. Front USB ports are for handy use of external drives like flash drives.? Monitors are available in different models, category and screen sizes. Some monitors are called LCD monitors. These are absolutely thin and lightweight. Merely 2inch in depth and the screen is flat and square. Normal monitors also come with flat screens. It is up to the buyer to decide on the one he / she can afford.? If one wants to watch TV then a TV tuner can be added to the PC.? Your PC can be a good sound system with some speakers. Speakers with surround effect cost a little higher but really sound good. There are many desktop speakers available in the market with a vast range of prices and features.? The CD drives are no more called CD-drives. These are now combo drives. In a combo drive you can play DVD, ACD, MP3, CD?s and can write your own CD?s. Conventional CD drives and CD writers are also available.? The newest mouse type is the optical mouse. In this mouse there is no roller ball attached. A laser ray is used to move the pointer.? If you need to take printouts on a regular basis then go for a printer. The latest category of printer is called all in one. In this printer you can take printouts, can scan and also photocopy. Though the price of this machine is little on the higher side but it really is a utility product.? After assembling the Personal Computer you need to choose an operating system. Windows and Linux are the two widely used OS.? After installing the OS the required software are installed. It totally depends on the working requirement.After all these steps your PC is ready to use. An annual maintenance is good for your PC.Paul has been providing answers to lots of queries through his website on a wide variety of subjects ranging from satellite phones to acne.

***Computer Support***

Lets assume you are already using computer systems running some version(s) of Windows. One thing is a given, if you own computers and you are running Windows; you will have problems. This is nothing against Microsoft Windows. It's just that writing a computer operating system that will work with thousands of programs running on a thousand different computers is an impossibility. So the best thing you can do is prepare for when a problem occurs, and it WILL happen at the worst possible time.If you are running a business and your computer systems are critical to your operation and assuming you are not already a computer expert, your best support solution is to enter into a support agreement with a qualified service organization. This is also one of the reasons why you want to use PC's running Microsoft Windows inspite of the inherent problems. No matter where your business is located, you will usually find a service organization within a 25 mile radius of you that can support the Windows platform.Look in the phone book, check them out. Talk to them. Many times you can tell what type of service they are going to provide just by talking to them. Have them visit your place of business, familiarize them with your business tools and practices. Make sure they are familiar with what your support requirements are. If it is a one person shop, find out who supports them when they go on vacation or get sick and make sure their replacement is familiar with your systems, as well.Check out their service agreement. First of all make sure, everything is in writing. Some points to look for in any service agreement:* Guaranteed response time. Be realistic here but at the same time be real clear on what your needs are. The quicker the response you require, the more it will cost.* On-hand replacements. If your printer fails can they at least replace it with something similar until the repair part arrives in three weeks? Will they stick around long enough to make sure the replacement printer works with your existing systems?* Contractual obligation to find a solution, even a temporary solution. The more specific you are here, the less chance there is for misunderstanding.* Periodic maintenance. Many problems can be avoided if periodic maintenance is built into the program. "An ounce of prevention is worth a pound of cure," goes double with computer systems. And make sure it is clear what they do and how often they do it. Keep in mind your Windows will run a LOT more reliably with a periodic maintenance program in place.For the last twenty years I have been the IT service manager and lead engineer for the top computer dealer in my area. I also spent nine years as a manager, network administrator and helpdesk administrator for several Fortune 500 companies.

***Building A Computer - Picking Components***

Picking the parts for your computer is one of the most important things in building a computer, because you cant assemble a computer without the parts! Picking parts for computers has become much easier than before, because things have been standardized, however, you need to make sure everything will fit. The first thing to think about when choosing the components for your computer is what you are going to be using it for. If you are creating a computer for just checking your eMail and using word, you are going to need much diffrent parts than a computer that you are going to be using for gaming.CPUThe first thing you should pick out about your computer is what CPU you are going to use, because it determines what motherboard you are going to get, which determines what other components you get. There are two main CPU manufactruers, Intel and AMD. Both have their Pros and Cons, but they are pretty similar. I would suggest using AMD, because they give you a little more bang for the buck.Here is a brief overview of the diffrent Intel and AMD CPUs:
Budget: AMD: Sempron
Intel: Celeron DMidrange: AMD: Athlon 64>br>
Intel: Pentium 4High End: AMD: Athlon64 X2
Intel: Pentium DIf you are spending below $500, I would suggest a budget proccesor, Between $500 and $1000, midrange and $1000 and above I would suggest a high end proccessor.Motherboard
Choosing the right motherboard is vital to building your computer. First, make sure you find a motherboard that has the right socket type for your CPU. Then, check the diffrent features of the motherboards you are looking at. If you arent going to buy a video or sound card, make sure your motherboard has onboard video and / or sound. Other things to check for on your motherboard are the hard drive interface, graphics card interface, expansion slots, the memory size and speed. Also, check for the chipset. There are too many to talk about, but generally Intel and nVidia chipsets are better than the other ones. Now that you picked out your motherboard, you know what to look for in your other components.RAM
Getting the right speed and amount of RAM is vital to the speed and stability of your system. If you are running XP, you will probably need at least 256 or 512Mb of RAM. If you are going to be doing anything memory intensive, gaming, rendering or just want a faster computer, you should get 1Gb. Make sure your motherboard has enough DIMMs and the right type of DIMMs for your RAM. Also, be sure to check the speed and CAS Latency.Hard Drive
Now its time to pick your hard drive. There are few variables in picking a hard drive. The first, and most important is size, 120Gb is usually enough for most people unless, you are going to be storing alot of pictures and video. Also, make sure you get an HD with the right interace that fits your motherboard. Almost all motherboards have IDE, but some have SATA (Serial ATA) Which is a much faster hard drive interface and uses a thinner cable which helps with airflow in your case. There is even SATAII now, which is twice as fast. Also look at speed, almost all desktop HDs are 7200RPM and Cache, most are 8Mb, dont buy a HD below those standards. If you want to spend some money, you can get 2 HDs and run them in RAID which increases performance.Video Cards
If you are going to be doing any gaming, be sure to buy a video card, if youre not, onboard video is fine. The first thing to check for is the interface, most are AGP or PCI-E. I personally like nVidia cards better. If you are going to be doing graphic intensive games, I would suggest at least a 6600. If you have alot to spend, go with a 7800.Optical / Floppy drives
Another thing you are going to is a CD drive, most are IDE. Get a DVD Burner if you are going to use it. Also, you should get a floppy drive, they are only $10ish and you might need it to install drivers when building your computer.Case and Power Supply
Make sure you have a sufficient power supply!! If you have a high end computer, you should get a 450W PSU. Otherwise, 350W should be fine for most people. Most cases are ATX, but make sure it is the same type as your motherboard (ATX, MicroATX, BTX, etc...).Be sure to make sure all your components are compatible!Chris Silop, owner and admin ofhttp: / / www.syschat.com / Go there for more articles and forums on computer hardware

***Learn Hardware and Design Your Commercial Product*** I am unimarter UniMarter
***Learn Hardware and Design Your Commercial Product***

I am certain the first question in everybody?s mind is: ?Why should I learn this tiresome hardware design in my spare time? I like to listen music, to play games, and to eat pizza. I just want to relax!?There is absolutely noting wrong with listening good music and eating pizza in your spare time, but... Living our life is, unfortunately, harder and more demanding with each passing day. If you have a good job today, you also have 75% chances to lose it, tomorrow. This is the new trend in our social life: jobs are not secure anymore. Even worse; if you do manage to ?keep? a job for sometime, you could discover, after ten years of dedication and hard-work, you didn?t manage to set aside your 100000 $ ?safe cash buffer?. Realistically, our life today means a permanent search for the next job, a never-ending and terrifying resume work, and also an acute lack of sufficient money for anything.Our society is polarized into employers and employees; between the two, being an employee it is far tougher! Some time ago a manager was required to know how to work with many, psychically different employees; today, it is the employee who must know how to ?deal? with the managers. More often people retire and they have to sell their homes, because they cannot afford continuously increasing costs of living--no, Sir; not anymore. Well, think ahead tiger.Now, which is the right way to become an employer? If you want--mind this, please: only if you want to--you could start working on becoming an employer today, and hardware design is one (important) way that leads to building your own commercial product and your future business. Besides, it will also increase your chances of employment, so... there are only benefits ahead for you. Please note, our entire social activity it is strongly--if not totally--dependent on hardware, firmware, and software technologies.The first thing you should know about hardware design is, it doesn?t work by itself--well, not much. Hardware it is driven by firmware and / or software most of the times. This complicates things a little, but not too much--don?t worry about this. Now, let?s detail the action plan, a bit. The first thing you need to do is, start with a reasonable life-plan. For example, you could decide in ten years from now you are going to start your ?J J Hardtronics Technologies Ltd.? business. Ten years is a good time-buffer, in which you will learn everything you need to know about hardware, firmware, and software design. However, please be aware the most important thing, during these ten years, is to discover your future commercial product!There are millions of good commercial products waiting to be discovered, and do not look at the high-end technological monsters like cell-phones; this market is so fiercely driven by competition that the best thing is to stay away from it. This doesn?t mean you cannot design a good product for the cell-phones industry if you want to. A quick example is a cell-phone utility software program, or a game.Truth is, the most beneficial applications are the industrial ones. There are thousands of industrial sensors that may be embedded into nice applications; a quick example is the acceleration sensor, or the one that measures the O2 concentration in water. You could design commercial motor-drivers, particularly for brushless DC or steppers motors. Other promising applications are: designing an instructive toy; you could break into the display-signs industry; or you could start building light-organs if you are a true music lover. The analog light-organs were a mandatory accessory in the 60s and 70s; without one, you simply couldn?t understand music, because you missed the related visual analog equivalent--please, take this last one just as a personal opinion. (The right way to relate colored light to music is: blue for low frequencies produced by the bass-guitar or drum, then green for solo-guitars and normal organ notes, red for voice, and finally yellow for the highest and most delicate frequencies which few people manage to hear.)I have seen an automotive coolant sensor controller selling very well for 35 $, and it contained only 2 transistors and few resistors; a temperature transducer was efficiently sold for 20 $ and it contained only resistors! A friend of mine has sold for half a million dollars the license of a tiny, intelligent controller for boilers. Please note, he was a beginner designer, and the application itself was nothing past beginning hardware design level. Of course, my friend was very lucky to find the right people who needed that particular application, and who were willing to pay handsomely for it. This is in fact the difficult problem: finding the right and the needed commercial product, and this is why I said you should allocate ten good years to research the market, or to find the opportunity. Sure, you could discover even ten commercial products in ten years--the more they are, the better it is!So, the need to become an employer and of improving your skills are sufficiently strong motivations to start learning hardware design. You could still be unclear about why hardware design in particular; why not firmware, or even software design? This is true, and you could do it anyway you want; however, starting with hardware design it is particularly beneficial. First of all, hardware is the beginning of the hardware-firmware-software chain, and it is best to start everything from the very beginning, one step at a time. Secondly, hardware design helps building your commercial product as an independent unit, or as a perfectly contained application. Next, the range of beneficial hardware applications it is way larger, and the competition is a bit less brutal, when compared to firmware and software. On the other hand, hardware design is going to lead you, naturally, to firmware and software design. My belief is, starting with hardware design it is the best method of learning, because you take everything from ground up.All right, I am certain you are motivated enough by now. Your next question is: ?How do I do this?? You see, this is in fact the easy part! Incidentally, you could start by visiting my home site, Corollary Theorems. Have no fears, my friend; you are going to discover that hardware, firmware and software design are very easy to learn, and they are even fun!Little relaxation in your spare time it is very good and quite necessary. Although you do not hear much about this, lately, when I was a bit younger we were encouraged to experiment with ?active relaxation?. This means, by reading an instructive, useful book, you could get the same level of relaxation as when listening music, or playing PC games. However, the lecture of a good book is going to enrich your level of knowledge, and you will gain valuable skills, instead of just ?killing time?. This is the theory behind the active relaxation concept. Nice, aye?O G POPA is Professional Engineer in BC, Canada. His home site is Corollary Theorems at http: / / www.corollarytheorems.com

***Taming the dsPIC30F4011 Monster*** Warning! This article unimarter UniMarter
***Taming the dsPIC30F4011 Monster***

Warning! This article contains graphic descriptions. The readers may experience anxiety, confusion, or a burning desire to ?start working immediately?. Professional guidance it is strongly advised!Unfortunately, it is sufficient to see the name of the beast, dsPIC30F4011, and many readers are going to shy away, or even burst into tears. No, dear friends, there is nothing to fear, and I intend to present how you could easily tame this terrifying dsPIC30F40111 monster and put it to work for you, into many beneficial applications.Now, the first thing you need to do is to capture the beast. For this, you have to take the jungle path--also known as the ?Internet?. Walk up to the monsters? lair, Microchip?, and there you could capture, or purchase one dsPIC30F4011 animal for about 12 pieces of silver.Once you bring your wild creature home, analyze its shape and, mostly, its behavior. You will see the beast looks like any ordinary monster IC of the DIP40 type, and this is good news, because it is best to use through-hole IC type of beasts, during hardware / firmware development work--some of them could pass away while experimenting, so... You think, probably, the 40 legs the monster has are not sufficient for your particular tasks. Do not worry about this, because you are going to discover means to multiply monster?s legs to hundreds of them, just like the truly ferocious monsters! Well, this is all about the shape of the beast, and you can see there is nothing impressive about it. However, you also need to study monster?s behavior; this time a bit more careful.Please be aware there are thorough treaties--also known as ?Data Sheets?--where the dsPIC30F4011 behavior it is described in details, and I will only point out few of the most terrifying features. First, our monster has Flash memory, about 48 Kbytes, and this is very good, because we can erase sucker?s memory whenever it goes nuts, or when we want to teach it new tricks. Next, our monster has 1 Kbytes permanent memory of type EEPROM, and this allows us to store there various configuration data, or to work with adaptive-learning firmware routines. The presence of this EEPROM memory tells us, in fact, our monster is of good quality!Now, the most terrifying aspect is, our monster belongs to the 16 bits family, but my advice is to ignore this. Handling 8, 16, or 32 bits monsters it is all the same; the only significant difference is in the tools we use to tame the beast. Another shocking feature you are going to discover sooner or later is, our monster belongs to the ferocious dsPIC? family, hence it is capable of DSP (Digital Signal Processing--please read my articles about this) and of very fast mathematical calculations. This is, again, very good news, because we need both fast and very intelligent microcontroller-creatures. Regarding its reflexes, our monster works at either 20 or 30 MIPS (Mega Instructions per Second), which should be fair enough for most demanding applications. In order to feed it properly, you should know this animal likes only regulated DC voltage of 2.5 V up to 5 V.Our 40-legs creature is capable of UART, SPI, CAN, and I2C communications. In addition, it has 6 PWM channels, because it appears it has been specifically bred for motor control applications--ugh, scary! The beauty is, it also has ICSP (In Circuit Serial Programming), and this allows us to do many annoying and nasty things to it. Ha, ha!What else... Ah! Nine of those ugly crooked legs are capable of 10 bits Analog-to-Digital conversion at maximum 0.5 Msps (Mega samples per second); then, about 30 legs are capable of general I / O, and 3 of them are also external interrupts. Wow, the Interrupts! Here is where the power of the monster actually lies! The dsPIC30F4011 beast has no more and no less than 30 interrupt sources, with 8 selectable priority levels.Fact is, we could go on and on, but it is better to keep it short; besides, I would like you to discover few interesting things for yourself. Now, it seems our monster promises a lot, but the problem is: ?How do we tame it?? Unfortunately, we cannot use the good, long-time tested methods of fire, hunger, and chains. What we need are MPLAB? ICD2 Debugger / Programmer and C30? ANSI C compiler. I know, they are both new tools, but they will do the job--trust me with this one. Please be aware you can download for free C30 compiler, fully functional for 60 days, from Microchip.Now we have everything we need to start the infernal process of taming the beast, and I am certain you think this is a long and very difficult burden. Well, it is not. What you need is a good incantation, like the multitasking one described in... No, I will not make it that easy, but I will give you a hint: you will discover the book with the ritual I am talking about at Corollary Theorems--my home site. You will also discover a good cage there to contain the monster, securely: its name is HCK (Hardware Companion Kit) V2.2.This is all! It should take you a couple of months to break the dsPIC20F4011 monster down. Then, you will have a yoke-beast ready to perform everything you need: all your tasks and all applications! I am certain your little monster is going to repay you back nicely, for all your efforts. In time, you two are going to become good friends, and you will come to love and respect your little dsPIC30F4011.O G POPA is Professional Engineer in BC, Canada.

***What to Look for in a Home - Office Graphics Card***

Let?s talk about some specifics for the average home / office PC user. This PC is used for word processing, spreadsheets, viewing photos, and even watching a DVD movie or playing a 2D game. Most all of these functions are handled easily by today?s low-end graphics cards.To accomplish these tasks, you can get by with a 32-64MB card, with a clock speed around 166MHz. You can find a good card with these specs for $40. Most of them will have only a VGA connector, but you can find some with DVI and even S-Video for more like $100.Prevent eye fatigueIf you are looking at spreadsheets and documents for hours on end, the best thing you can do is get a card that has a high refresh rate, at the resolution you work at. A minimum is 75MHz. The higher the resolution, the more memory is used on the card and the harder it is to refresh. If this rate drops below 75MHz, your eyes will be fatigued from the flicker of the monitor. Find out what your monitor can support at the resolution you use, then get a card that can pump it out that fast.Don?t get features you don?t needIf you just play on the Internet, or balance your checkbook on the computer, you don?t need all those available connectors on the back of your video card. Don?t spend a lot of extra money on a card that has features you?ll never use. If you?re just playing solitaire, it?s not likely you?ll notice the difference in a $50 card and a $500 card. Another good thing to check is the software that comes with the card. Most come bundled with nice utilities to change resolution and even add some effects to the way XP looks. A lot of them also come with a game or two, which are usually a good indication of what the card can handle.John Gibb manages http: / / www.computer-and-printer-reviews.com

***CD Burning Problems - A Quick and Easy Guide for Software & Hardware Conflicts***

When it comes to problems with CD Burners things can get ugly and users most of the time gives up hope of ever completing a successful CD Burning session. PC technology can be confusing as almost anything could cause a CD Burning problem such as software conflicts, faulty hardware and bad media brand of CD-R or CD-RW discs.So where does one start when it comes to troubleshooting a CD Burning problem?That?s easy, start looking at the hardware, the CD Burner itself and the motherboard ? this way you are making sure the key piece of the CD Burning process is actually working.Apply the most recent firmware for the CD-Burner as this will fix any bugs that your model of drive may have, make sure to check with the CD Burner manufacture before doing so.Make sure the CD Burner drive is recognized in the BIOS and has the manufacture model listed. Install the latest BIOS update for the PC but again make sure to check with the OEM of the PC before installing.Software conflicts can be caused by almost anything installed onto the Operating System such as anti-virus software, screen savers, drivers among other things. It?s important the System is free of any virus?s or spy ware software as these can cause major problems for the CD Burning session.It?s advisable to troubleshoot any software problems in ?Safe Mode? of the operating system as this makes no programs have loaded during start-up.Uninstall any programs that are no longer used making sure to free up more resources.
Do the usual house-keep on your PC by deleting temp internet files, cookies etc and also defrag the system. It?s important for the CD Burning process that the system has the resources to support the session.People seem to get hung up on what would be the best brand of CD-R or CD-RW disc. This could have a conflicting answer but from experience it all depends on the model of your CD Burner. Some drives take well to using TDK when others don?t, the same with Kodak and even unbranded discs. The best advice would be to purchase a number of different branded discs and find which one works best for your drive.If problems still do occur during the CD Burning process then contacting technical support maybe required. You could also go in-depth by using valuable resources on-line that provide amazing technical guide.Gavin Duncan is the editor and publisher of http: / / www.cd-burner-help.com , a site to help people facing problems with Burning CD?s.

***Buying a Hard-drive - How Much Space Do You Need***

For novice buyers of computers or of a separate hard drive, it?s often hard to tell exactly how big you should go. Many people don?t even have a good idea of what a "gigabyte" is or how much space there files will take up. How exactly do you figure out how much storage space you?ll need?If you already have a computer, this is actually an extremely easy thing to figure out. Right-click on your C: drive under the My Computer option, and select "Properties." This will bring up a little pie chart that tells you how much space you have and how much you are using. It will tell you in "gigabytes" or "GB", a unit of storage space. Once you?ve found out how much you?re currently using, you should make sure that you get a hard drive that has at least a little more ? you?ll want at least 20-25% more than what you?re currently using, just to allow yourself room to grow. If you?re on the low end (under 20 gigabytes), you should get even more, mainly because newer programs will take up more and more space. What if you don?t already have computer space to measure? It depends on what you?re doing with it. If you?re just using your computer for basic business functions (e-mail, typing, etc.) then you only need 20-40 gigabytes. If you?re using it for games, you?ll want as much as you can get. If you have more advanced business functions (such as graphics design), then go for at least 100 gigabytes or so. The most important thing is that you don?t want to run out ? if you do, you?ll have to delete something or buy a whole new drive.Teve Torbes has interesting opinions on the subject of air purifier things, and he has produced a forklifts web site.

***How to Download Your Old Computer to the Highest Bidder***

When you think trash, you surely don?t think about your old, trusty personal computer. But that?s exactly what will become of it when you make the inevitable move toward your next laptop or desktop. And, yes, buying a new computer is inevitable, considering the pace at which computer technology zips along. Just think?about a handful of years ago, a fast microprocessor for a laptop was at 233 MHz. Now you?re looking at about at least 2 GHz! That?s Giga, with a G.So eventually, you will want a computer that can handle the latest software, the latest games, and the latest interactive Web sites, and then you?ll have to throw away your old computer, right? Wrong. Try selling your used computer instead. Throwing out your computer is one of the worst things you can do. For one, your computer may be useful for someone out there, even if just for scraps.Trashed computers and other digital equipment also make up one of the fastest growing, and most dangerous, new trash ?categories? out there in your neighborhood landfall. On one hand, computers are generally bulky and made of plastic and other materials that won?t be breaking down in a landfill for the next few million years. What?s more, other materials in your old computer are highly toxic to the environment, like mercury, lead and cadmium. They?re so toxic that their actually name in the waste-management field is ?toxics.?You don?t have to be a techie or a scientist to understand the danger in that?nor the benefits of selling your computer. On the Internet, there are a vast number of auction and classifieds sites, some better than others, where you can ?download? you computer to a worthy buyer.Before you boot up your replacement laptop or high-performance PC, however, be sure you read and compute the following tips. These tips will help you avoid the crashes and shutdowns that befall the computer seller who doesn?t do his homework first.Hold onto all of the operating system and software manuals that came with your old computer. This will add value to your sale, not to mention it will make you a trusted seller for offering up these helpful books to the buyer.Erase all personal information from the hard drive. And we?re not just talking about simply putting stuff in the ?trash bin.? It?s extremely important to purge all data from your computer?s memory repository, even from invisible backup files on the hard drive. If you?re not sure how to do this, ask your IT expert at work or a techie friend for advice. You don?t want the next user to have access to your bank accounts, old e-mails, and other private info, do you?Uninstall any application from the hard drive that you?d like to use on your next computer, keeping the installation disk and the software serial number for yourself. When it comes to software, the manufacturers made sure that you never really own software, you license it. So you don?t get free reign to keep software on multiple computers. You only get one license, so you need to bring your licensed version with you to your new computer.Do your homework on your computer?s worth. Just like you would for a car, check around at other classifieds and auction sites to see what other people are selling your make and model for.Be sure you want to truly get rid of old faithful. You may be able to repair your old laptop rather than buy a new $2,000 Centrino model. Or you may be able to add RAM memory and a new hard drive to your four-year-old desktop rather than invest in a new $3,000 multimedia masterpiece. In other words, do a thorough cost-analysis of what it would take to rebuild your old computer, versus what it would cost to sell it and buy a new one. And check your heart too. You might be surprised just how attached you are to your old faithful.Once you go through these steps, you are prepared to make your move and sell, sell, sell. And then, of course, you?ll be ready to start on a whole new list of steps?for buying a new computer.

***Should You Upgrade Your Hardware PC?*** What if you found unimarter UniMarter
***Should You Upgrade Your Hardware PC?***

What if you found that your computer is out of date? You probably want to upgrade your computer since you have no choice to do so. Your works depend on your hardware computer upgrade. That?s how you going to have a good result.But before you make any further step, try to learn about your computer. Search all options and ask for advice. Only after this you can go and buy a new component. It?s also useful to check if you really need an upgrade.Sure, it?s not funny if you keep your old computer but you still loose data when you do your works. Its just a matter of time before you experience a hard drive problem when you still using your old computer. You dont want to loose your data, right? Of course most people only think of backing up their data after they experience a problem. Don't set yourself up for a data loss disaster. Check what hardware you need for your computer.If you have problem with your hard disk, such as crash when you do your work, better you have it renewed. Most people upgrade their hard disk to increase the size so that they can use it for games, movies and playing a lot of music. A 20 GB hard drive is sufficient to keep new office and internet applications, and all your files and data. A medium sized hard drive would be around 40 GB and the maximum would be around 60 ? 80 GB.You can choose which perfect for your work. Of course the price is also depending on the capacity of your hard disk. If you are a gamer, you may want to have high capacity hard disk such as that 60-80 GB. But if you just used it for your writing, a 20 GB is more than enough.Another hardware you may need to upgrade is the RAM or Random Access Memory. This memory keeps data that is being worked on now and may or may not be transferred to the hard drive that represents the long-term memory of the computer. Current processors can perform an enormous number of operations per second. Almost all computer have 64 MB RAM and often 128 MB. If you want to run newer applications on your PC then you must upgrade to 128 / 256 MB RAM. A lot of people who upgrade from 98 to Win 2000 discover that their computers lock up very often. This is because they don't have enough RAM.So, those are only some part of hardware you might want to upgrade. There are others such as motherboard, CPU or port which you can upgrade. Your action depend on your need.About the Author: Tony Gevano interest in observing people?s way in choosing things has made him become a writer in various kinds of materials. He wrote almost anything he likes. You find his writing in different Website, among them is in http: / / www.d-tools.info

***Advanced Tips on Speeding Up Your PC***

Other then keeping your HDD free of viruses, spyware, and ad-ware at all times, there are other methods for speeding up system speed which you may like to employ. One of these is overclocking. Overclocking is a method of increasing your system speed by increasing the frequency at which your CPU operates at. If this interests you, please refer to our guide on overclocking.Other methods of keeping your computer up to speed include: -Running defrags / scandisks on your PC once to twice a month
-Upgrading your RAM by installing faster, or more memory
-Formatting at least once a yearRunning a defrag is easy. You can find this windows tool in programs--->accessories--->system tools. You can also find scandisk on this same menu. Running defrags / scandisks will help to improve your hard drive read / write time. Scandisk and Defragmentation work to fix corrupted files on your PC. These files become corrupted when you restart your computer by using the reset button, or by being careless with your hard drive (like not bolting it properly to your case or removing it constantly).You could also use a tool called a Registry Fixer. Sometimes, especially if you have been infected recently with a virus, spy-ware, or ad-ware, these programs work to fix your registry and repair certain errors. This is more for an advanced user, however, as some of these programs can be difficult to grasp.There are also several registry tweaks programmers have produced which improve startup and shutdown times by skipping some uneeded parts of processes. These are also recommended for advanced users as they can sometimes result in a hardware or software error, although such incompatibilities would likely be rare. If however they do cause a problem, post your problem on our forums and we will try to help.I am a young, aspiring computer engineer into Internet Marketing, hardware, software, web design, SEO and just about anything related to computers.

***Give Your PC a Monitor Makeover*** Whether you are crunch unimarter UniMarter
***Give Your PC a Monitor Makeover***

Whether you are crunching figures at a front office job or crouched over a blood and gore video game in some deep recess of your room, there is the right kind of screen available to suit your needs.Monitors are one segment where you are truly spoilt for choice.Be it a 15-inch, 17-inch or 19-inch CRT monitor* or a sleeker range of LCD screens*, there is a wide range to fit your budget. Hardware Software Articles: http: / / www.hardwaresoftwarearticles.com / archive / index.php / *Size and resolution*There are two aspects you must consider when selecting a monitor: physical size and resolution.Screen size is the diagonal screen measurement, usually in inches. For instance, a computer monitor display might be 14 inches wide and 11 inches tall. This same screen has a diagonal measurement of 19 inches, which is the screen size.Monitors also have an aspect ratio.This is the ratio between the horizontal dimension and the vertical dimension (horizontal dimension divided by vertical dimension). Common monitor aspect ratios are 4:3 (1.3333) and 5:4 (1.25). Basics: http: / / www.hardwaresoftwarearticles.com / archive / index.php / f-2.htmlA 4:3 aspect ratio means the picture is 4 units wide for every three units of height.Wide screen monitors are easier on the eye (and much more expensive).The higher the resolution, the greater the ability to render more detail. If you work with graphics or enjoy graphic-intensive games, you will need a monitor with higher resolution.With most currently available models being flat screened, the difference is in the size and picture quality. A resolution of 1024 x 768 is a good one for most users.*CRT monitors*If you've decided to get a new CRT, make sure it has a sufficiently high refresh rate. This refers to how often the screen is redrawn per second. With low refresh rates you can get screen flicker and eyestrain. Virus: http: / / www.hardwaresoftwarearticles.com / archive / index.php / f-14.htmlAim for a rate of 75 Hz for a monitor up to 17 inches in size and 85 Hz for any larger monitor.Another consideration for CRTs is dot pitch. The smaller the dot pitch, the sharper the image. Opt for a dot pitch of 0.26 mm or smaller.CRTs function very well at multiple resolutions, can display detailed graphics and can be viewed comfortably from wider angles.*LCD screens*One of the primary disadvantages of LCDs when compared to CRTs is their limited viewing angle. When viewing a LCD straight on, it looks great. But the screen will appear washed-out if you move your head over to the side and look at it from a wider angle.Also, LCDs are optimised to perform at a single resolution. Low-end LCDs have viewing angles of only 100 degrees, which won't give everyone crowded round your desk a clear view.For a standard 15-inch LCD, try to get a 140 degree viewing angle. Increase that by 20-40 degrees when shopping for an 18-inch LCD.The brightness of LCD monitors is an important factor. LCD monitors have several backlights that provide illumination. The backlights in a LCD are good for 10,000 to 50,000 hours of operation. Ensure that the backlights come with at least a one-year warranty. Messenger: http: / / www.hardwaresoftwarearticles.com / archive / index.php / f-7.html*Making a choice*LCD screens generally cause lesser strain to eyes than CRT monitors.CRTs have better graphics, but they tend to occupy five times as much space.If you are a gaming freak, then a CRT is a better option as it is best for any graphic interface.If you want the sleek look, an LCD is meant for you. It is widely used in banks and treasury and trading rooms.Adam Fletcher is the webmaster of Hardware Software Articles http: / / www.hardwaresoftwarearticles.com.

***Moving to a New PC*** Getting a new PC is exciting and a unimarter UniMarter
***Moving to a New PC***

Getting a new PC is exciting and a pain. It's exciting because you get a faster processor, more storage and all the latest stuff even though it's outdated as soon as it hits your desk. The pain comes with re-installing all of your programs, re-customizing your preferences for programs, applications, and Windows, and transferring data to the new PC.It can be simplified by using a bootable external drive or something similar and letting it load everything on the new PC. However, if you are like me, you probably had a few problems here and there that couldn't be found and fixed. So it's better to start with a clean slate.I am getting a new PC at the office and my hard drive crashed on my laptop. There's nothing I can do about the laptop, but I kept it simple since it's a supporting computer rather than the main PC. I often used a remote application to connect to my desktop from the laptop. Therefore, the laptop had few loaded programs and data. I did try to make a backup of my user profile before the crash, but it was having too many problems and the backup didn't happen.As for the work PC, here are the steps I took to prepare for moving to a new computer with the limited resources I had.
Ensured all my work was on the network server. I kept backups of important files on the hard drive as a safety measure after my past experience.Deleted everything that I put on the hard drive.Made backups of data files such as the password manager's file.Took a screen shot of my Windows desktop, so I can rearrange things on the new PC to closely match the way I had things on the old PC.Used Belarc Advisor to create a print out of what's loaded on the machine.Changed my password to a temporary one that's nothing like my original so support could get in when I wasn't at my desk.Copied the properties of specially-made shortcuts like the one I use to lock the computer with one click.If you use Outlook, make notes of your preferences and options. Mine didn't get transferred.If you use the Office toolbar (typically on the side or top of the screen), add the programs and folders back in based on the screen shot you took earlier. I could not remember how to change the icons in the toolbar, so here's how: right-click on the icon you wish to change, select Properties, and Change Icon.Print the list of fonts loaded on your computer if you've added additional fonts.Meryl K.

***Nvidia Geforce 7800 GTX Review*** Nvidia has done it agai unimarter UniMarter
***Nvidia Geforce 7800 GTX Review***

Nvidia has done it again, with it's newest video card, the geforce 7800 GTX. If money is no object and you demand the best, this is the video card for you.The 7800 GTX, which promises 600 MHz, 256 MB of 256-bit DDR3 memory and a graphics core clock speed of 430 MHz, is the absolute fastest video card, to date, that money can buy.Despite the high clock speeds, the 7800 utilizes a single-slot cooling solution. This is made possible because of the processor size which is 20 NM smaller then their previous 8600's. Also contributing to the cooling of the card is the improved power managment system, which automatically turns off unused portions of the chip.The 7800GTX is equipped with 24 pixel shader units and 8 vertex shader units. With over 200 GFLOP's of shading avaliable, Nvidia raises the bar, once again, on video card's graphics and performance.This is all in just one videocard, pair them up in SLI mode and you have the best video cards in terms of speed, stability and appearance. One thing to watch however, when running dual cards in SLI mode, is that unless you have a top of the line processor, such as the FX-55 you may find your video cards waiting on your processor to catch up. In this case you may want to hold off on getting both cards untill you upgrade your processor.Nicholas Spriggs is the author and creator of desktop-computer-guide and is dedicated to bringing you the most accurate information on computers and all things relatedhttp: / / www.desktop-computer-guide.com - Your guide to computers

***Your Printer Is Out Of Ink -- Now What?*** We?ve all been unimarter UniMarter
***Your Printer Is Out Of Ink -- Now What?***

We?ve all been there. You?re in the middle of printing out an important document and your printer suddenly stops. It?s the dreaded ?out of ink? message. So you pull your backup ink cartridges out of your desk drawer and replace them. Wishful thinking, right?Most of us just don?t plan ahead -- no matter how many times this has happened to us. When we buy ink cartridges, we tend to just get one set of black and color cartridges. The cost of ink is so high that buying more than one set is just too expensive for most consumers. Thankfully, there are less expensive options out there ? and you don?t have to sacrifice quality.Option 1 ? Avoid Staples, Best Buy, and other large retailers altogether. You?re never going to get a good deal on ink cartridges since they only sell name brand replacements. Instead, do your homework on the internet. There are many reputable websites out there that charge up to 80% less for cartridges.How is that possible? Rather than selling name brand replacements, online ink retailers sell compatible and remanufactured cartridges. There cartridges are technically just as good as the originals, and can be purchased for half as much money. As an added precaution, however, we recommend buying ink cartridges at sites that offer 100% guarantees. In the online world, you never know what you?re getting. My advice -- run a search on Yahoo for ?ink cartridges.? Visit the first 5 sites. Find the web site that offers the best prices, lowest shipping costs, and a 100% guarantee.Option 2 ? Refill your ink cartridges. It?s not as bad as you might think. And best of all, this is definitely the cheapest way to go. You can fill your ink cartridges up to 10 times with a single ink refill kit. There is obviously some work to this. You basically use a syringe to inject ink back into your original cartridges. If you do this correctly, this is no spillage, and you?ll be up in running in no time. It takes a bit of practice to master the art of refilling ink cartridges. Don?t get discouraged if it takes a couple of tries before you get it down.Bill Smith is a printer expert who has specialized in ink cartridges and refill solutions for over 5 years.
