Remove viruses, spyware, and other malware. Defragment your hard drive primarily an issue for Windows computers. Choosing the Right Upgrade It's important to understand at least the basics about what's going on inside your computer, and what a hardware upgrade can and cannot do.
You can't turn a slow computer into a fast one simply by increasing the size of a hard drive. Likewise, upgrading the computer's processor probably won't make a computer that's prone to crashing more reliable. A good sign you could benefit from more RAM is if your computer slows down a lot when you try to use several programs simultaneously. Put in as much RAM as the computer will support.
Moderate Graphics card Because graphics processing uses RAM, a graphics card upgrade may improve overall performance.
Be sure that your motherboard can support the new card you are installing. Moderate Hard drive If you're running out of storage space, you can upgrade to a bigger hard drive with more storage capacity. If your computer is slow, upgrading to a faster hard drive may improve overall performance: In traditional drives, the faster the drive spins, the faster data can be read and written. So upgrading from a drive that spins at 5, rotations per minute rpm to a 7,rpm drive may speed up your computer's performance.
A solid-state drive SSD is another option. SSDs don't spin, so their speed isn't measured in rpms. But they are significantly faster and because they have no moving parts less prone to mechanical problems than traditional drives.
With this computer hardware tutorial you will master this important program and increase your chances for getting the job position that you have always wanted! Free tutorials computer hardware - PDF. Computer Fundamentals. This PDF includes aspects of the underlying hardware as well as how we represent information, and how we can program a computer at the lowest level.
Introduction to Computer Design. Computer Basics for Kids. Computer Network. Computer basics. Computer Architecture. Basic Computer course book.
This PDF book is designed for very novice computer users. It often contains oversimplifications of reality and every technical detail is purposely omitted. An Introduction to Computer Networks. This book is meant as a serious and more-or-less thorough text for an introductory college or graduate course in computer networks, carefully researched, with consistent notation and style, and complete with diagrams and exercises. Do I plan on underclocking my computer?
Underclocked parts run cooler, often enabling passive cooling options to be used, which leads to a much quieter system, and you'll also save on power.
However, you'll lose performance from the CPU. Can I use any of the parts from my old computer? On the other hand, if you are upgrading from a fairly new machine, you may be able to use many of the parts. All of this assumes the old computer will no longer be used. If you, or someone else, is going to continue using your old computer, it's probably best just to leave it intact.
One important point — if you are selling your old computer it's a good idea to erase the hard drive before giving it to its new owner. Special precautions must be taken to ensure that you are not giving away your sensitive or personal information. Don't forget that a simple 'delete' command does not actually erase the data on your hard drive. To avoid this, programs are available that will effectively 'shred' your data, making it unrecoverable.
Driver floppies or CD's that come with some hard drives may also have programs to do this, that write 0s or 1s either way, "blankness" to the whole drive.
Lower-tech approaches include drilling a few holes in the drive or taking a blowtorch to it. Obviously, either prevents it from being used again Be planet friendly and try to avoid this.
Since monitor technology moves quite slowly, you can probably keep your current monitor and use it on the new computer if it's of sufficient size and clarity for your work. The same can go for keyboards, as well as mice, printers, scanners, and possibly speaker sets.
On the inside, you may be able to take out the floppy drive, CD-ROM drive, and possibly the sound card and hard drive depending on how good they are, of course. Sometimes so much is used from the old computer, that the line between an upgrade and a new computer can become blurred. Reusing a hard drive is an easy way to keep data from your old computer. With most Windows operating systems moving a boot drive from one motherboard to another will entail a series of reboots and installation of new drivers.
Back up your data before trying this, and note that Windows will usually ask you to reactivate. Keep the licence key ready. Where do I find the parts? A few hours of research can save you years of regret, so make sure that the computer you build will do what you need it to do.
There are several places to download parts: Internet retailers generally offer the best price for new parts.
If a part needs to be returned, you may be stuck for the shipping; check return policies before you download. Auction sites like site and several others offer very good prices for used parts. This is especially useful for parts which do not wear out.
Returns can be problematic or impossible.
Some auctions may not be legitimate. Always check the shipping cost before you bid. Local PC shops - Their prices are often higher, but they may make up for this by providing a lot of expertise.
Get opinions from other sources, however, as they may be eager to sell you parts you don't need. Big local retailers often lack technical expertise and charge higher prices, but can be useful because they usually handle returns quickly. Also good if you need something right away. Trade shows that occur from time to time also provide a good place to shop, as the prices are often significantly reduced, and the variety of prefabricated computers built towards specific computing needs tend to be higher.
Also, your local town dump may have a special section for computers and monitors that others have got rid of. These can be more or less brand new computers with trivial problems such as a busted power supply or faulty cables.
Of course if the dump does have such a section, you should ask permission of those in charge. They're usually glad to let you go through it, but don't leave a mess. Taking advantage of this can yield incredible finds, with a price tag of nothing or very little.
