Looking to buy a new desktop personal computer system? This guide covers many of the basic items to examine when comparing desktop computer systems so that you can make an informed purchasing decision. Due to the changing nature of the PC Hardware industry, this guide will be periodically updated. Links are provided below each topic for a more detailed discussion on that subject.
Processors (CPUs)
Processor choices are a bit more difficult now then they were before. It is still really a choice between an AMD and an Intel processor. The difference really comes in how many cores there are in the processor and its relative speed. Each company now has a performance rating system that isn't really easy to compare. Due to the complexity, its best to refer to my links below for a more detailed explanation of CPUs for budget and uses.
Memory (RAM)
Most desktop computers now use a type of memory called DDR2. DDR3 is now finally making its way to PC systems but it is more expensive. In terms of amount, it is best to have at least 2GB of memory in the system and preferably 4GB. Memory speeds can impact performance as well. The faster the memory, the better the performance should be. When buying memory, try to buy as few DIMMs as possible to allow for future memory upgrades if needed.
Hard Drives
Hard drives really boil down to size and speed. The larger the drive and the faster, the better the performance and capacity. In a desktop, it is best to have at least 500GB or more of storage space these days. In terms of speed, they are pretty much all running at 7200rpm now. A few high performance 10,000rpm drives are available. Most drives use the Serial ATA interface now for ease of installation.
Optical Drives (CD/DVD/Blu-ray)
Most systems sold now feature DVD burners, even the budget systems. It is best to make sure that you get a multiformat DVD burner that can support both the +R/RW and -R/RW formats. Speeds should be 16x for the recordable speed. Dual or Double Layer media support is also a common feature although less likely to be used due to media cost. Options also include LightScribe or Labelflash support for burning labels directly to compatible media. Blu-ray is an option for those wanting to use their PC for the high definition video format.
Video Cards
Video card technology seems to change every three to six months. If you aren't really doing any 3D graphics at all, then integrated graphics may be just fine. Beyond this, there are a wide selection of cards. Things to consider include performance, the amount of memory on the card, output connectors and the version of Direct X supported. Those looking to do any gaming should really consider a Direct X 10 card with at least 512MB of memory onboard. Pretty much all new systems will use the PCI-Express graphics standard.
Extrenal Connectors
Many upgrades and peripherals to computers now connect through external interfaces instead of internal cards. Check to see how many and what type of external ports are available on the computer for use with future peripherals. Look for systems that have both USB 2.0 and IEEE 1394 or FireWire ports. It should have at least six USB 2.0 connectors and one FireWire ports. Many times media card readers that support various different flash memory cards for peripherals are also inlcluded.
Monitors
What good is a desktop PC unless it also has a monitor? Previously users would need to choose between a CRT or LCD monitor, but LCDs are pretty much the standard now because of their reduced size and power consumption. The real issue is more about size and cost of the LCDs. The price difference between 19-inch and 22-inch models make 22-inch the best overall value although 24-inch models are quickly dropping in price. Most all screens use the wider 16:10 format but some are now being released with a near 2:1 ratio best suited for movie watching.

Second, you can save a good chunk of money by getting computer parts at dirt cheap prices and assemble your own computer... a clone computer system. This system is "cheap" in price but not in quality at all. You can choose the component parts for your own system from renowned components manufacturers such as Intel, AMD, Seagate, Viewsonic, Logitech, etc the list can go on and on, but at dirt cheap prices here.
Buidling your own computer is fun. It does not need a rocket scientist to build it.
Third, if building your own computer seems too much an effort for you, you can get a last year model.
Fourth, you can get a recertified computer systems from
More info.
Fifth, another way is to get a good clone computer system. There are some fantastic clone computer deals here that Dell, Compaq and Gateway don't want you to know about. I've found some absolute great computer deals that were top of the line. Have a look at the prices on these ridiculously "cheapy" clone computers which Dell, Compaq and Gateway don't want you to know..
If you save money on a computer now you can afford to spend a little on upgrades in a few months time. Find out about the different types of cheap computer parts and computer system here. You can save even more by hands on and build your own computer. I've been building computers for years with no classroom computer training. I simply like doing it. It is in a way giving me the satisfaction of achievement. You can do it too if you want to. Do you know more cloned computers are assembled than Compaq, Dell, Gateway and IBM combined
I have been building my own computers from cheap computer parts since 1990 when I worked in STD Technologies Inc as Account Executive selling pc computer system, parts and peripherals to distributors, retailers and corporates. Hence, I know the sourcing for good quality brands with warranty at competitve prices. As from then I bought the parts and put them together of course at dirt cheap prices. Putting cheap computers together isn't hard.

10 Tips for Computers
By Jen Wilson
1) Memory - You can get the fastest processor out on the market, but you don't have anything until you load it up with RAM. We recommend at least 2gig (3 gig or more is better). Before buying the latest PC, consider upgrading your memory first. You will be surprised. See our electronics dictionary for information on purchasing memory. Look out for MRAM, the latest type of memory that offers the potential for instant operating system boot without the ordinary boot up process.
2) Bad pc memory - Bad RAM can cause many problems with your pc. Some symptoms include - blue screens, programs crashing, and shutdown of your computer for no apparent reason. Memory can be bad from the moment you purchase it. There is a free program called Memtest86 that can help you troubleshoot memory problems. Real easy to use. Must be on a bootable floppy or cd.
3) Static Electricity - Do not touch the hard drive (case) or monitor after walking on carpet. Good way to tear up something electronic. Try to touch something metal before putting your hands on them. Static electricity can cause catastrophic damage to a computer. If you are doing upgrade/repair work yourself, invest in a anti static wrist strap/pad. Inexpensive and well worth it.
4) Funny noises coming from computer - If you here "funny noises" coming from your PC, stop immediately. If you don't know a thing about them, call some one. It is not uncommon for fans to go out. They are inexpensive to replace, but can trash the whole system. Always insist on high quality ball bearing fans. Do not go with the cheap ones. Good quality fans will not cost more than $10.
5) CD Stuck - Ever wonder what that little bitty tiny hole on cd and disk drives was for? Stick a straightened paperclip in that hole to eject stuck cd/disks. Special note - How you format can cause the cd not to eject.
6) Video Card - Get a good one. We recommend NVIDIA with at least 128mg of built in memory. On board video (graphics card built into the motherboard) can cause lag. Onboard video cards use valuable PC resources. Put in a good video card, bypass the onboard video and notice the difference. Extremely good choice for upgrading your computer with minimal investment. Here is our article on how to replace a computer expansion card (click here).
7) New computer, break it in - We do not recommend buying extended warranties with a new computer. Why? Most of the time, if new electronic components fail, they do so fairly quickly. Leave your new PC on for two weeks without turning it off to give it a good trial/break-in period.
8) A cool browser zoom tip - If you are running Windows XP with Internet Explorer, hold the Ctrl key while moving your mouse wheel (if you have one). You can instantly zoom in or out!
9) No food or drinks - Go to the table if you want to eat or drink. Have you no manners? And say your prayers while your are there. Thank God, Jesus (click here) and the Holy Spirit for all of your blessings! God and your PC will love you for it.
10) Ergonomics - This is becoming more of a danger with more people spending more time at computers. Repetitive motion can cause carpel tunnel syndrome (swelling around nerves). Buy ergonomic keyboards (padded wrist rest are intended for resting NOT WHILE KEYING), get a good chair, and take breaks (stretch or walk around 1-2 minutes every hour). Keep your shoulders and upper arms perpendicular to the floor and relaxed.

Building Cheap Computers in 3 Easy Steps
Just a decade ago, the only people who put computers together were those individuals who possessed an extensive technical background. Advancements in technology have eliminated some of the complexities in how computers work. This change has resulted in average people who have a basic understanding of computers being able to build a system themselves. Whether you are interested in building computers to establish a new hobby or to start a business, you can so in only a few easy steps and on a shoestring budget.
The first step in building cheap computers is to determine the route you want to use to build systems. You basically have three choices when considering building cheap computers: build a system from scratch, expand on a bare bones computer, or upgrade an existing system. Building a system from scratch can be a rewarding experience. However, it is not for everyone. If you are impatient or are intimidated by mechanical tools, you are better to choose one of the other two options.
Regardless of the method you choose, you will follow three basic steps:
1. Plan
2. Assemble
3. Test
The planning phase of your project involves determining the specifications for the computer you want to build. Once you know this information you can start shopping for parts that meet those specifications. Your main considerations should be
hard-disk, memory, and CPU (central processing unit). The harddrive is important because it determines how much information you are able to store on the computer. While you could build a computer with a harddrive smaller than 2 GB (gigabytes), it is not recommended.
The harddrive and memory work together. The amount of memory you place in your computer will directly affect how the system is able to complete the different processes that you request when using the system. If you have no idea what size hard-drive and the amount of memory you need, you should consider the type of operating system you intend to load on the system. You can consult the manufacturer of your hard-drive or review the information on Cheap-Computer-Guy.com, which features a list of minimum harddrive and memory requirements for various operating systems, and use this information as a guide.
The equipment presented in this article includes the basics of a computer system. Of course, nowadays people want far more than the basics and you undoubtedly feel the same way. There are optional components available that you may want to add to your systems, which include CD or DVD drives, a modem or other communication component for Internet connectivity, or a video graphics card.
Once you have decided on the specifications of the computer you want to build, you are ready to assemble the system. In addition to detailed information about the parts you will need to build your computer, cheap-computer-guy.com includes step-by-step instructions for assembling a cheap do-it-yourself computer.
When you have finished assembling the computer, you will then need to test to make sure that the system boots and that all components are functioning properly. Once you have completed all these tests you will have built your own cheap computer.

Find The Best Deals And Discounts In Computer Sales
You will find while searching for computer sales, that there is no shortage of choices. The computer industry of today provides consumers with many different ways to obtain the personal computer you need. One perfect example is the cost effective method of recycling older computers. The best thing for you to do is do your homework, learn what option is best suited for your needs, and budget.
What is great about these recycled computers is that you can often times get the same great advantages of newer computers, at a much lower price. The key to getting the most from a computer sale is knowing the key features in the different types of computers. Computer sales often provide you with previous demonstration, refurbished, outdate, and over stocked models.
Over Stock
At a computer store, when new models arrive, the company must make room, thereby selling the older models. When we say older models, it could very well be that it was a model from the previous year, but in some cases even older. Buying an older computer does not mean you are missing out. Many of the "older" models contain many of the new capabilities that people want and desire in their computer. Generally, the holiday season is the best time to find these types of deals.
Outdated
Computers that are outdated are generally sold for a much cheaper price. Outdate computers are those that simply cannot compete with the technology of today. While some are sold at a steep discount, perfect for first time computer buyers, many are donated to schools or not for profit groups. Many parents, will purchase outdated computers for younger children that are learning and do not need the major capabilities of new models today.
A Refurbish and Renewed Computer Sale
While many refurbished computers are used or older models that have been made just as or close to their factory condition. In most cases, they have been refurbished by the manufacturer or have had some parts replaced to correct problems. You should be wary when buying these types of computers, while they are typically much cheaper, you may have to worry about a break down.
Previous Demonstrations Computer Sales
Many companies make use of computer only for demonstrative purposes for example as a store display or a convention. They are lightly used for the most part, simply showing the capabilities and features of the computer, but they sell at a discount. The computer may only be about three months old, but you still have the opportunity to grab a great discount. The best part about demo computer sales is that you benefit from what is left of the original warranty.
While a computer sale may seem great or the features of a computer may make you want to grab the item right off the shelf, you do not want to take the first deal you are offered. It is likely you can find it cheaper elsewhere. Additionally, in as little as six months or less, you might find that the price of the computer has dropped dramatically, sometimes by a thousand or more dollars.
Summary:
The key to getting the most from a computer sale knows the key features in the different types of computers. Computer sales often provide you with previous demonstration, refurbished, outdate, and over stocked models.
