Scan your windowsAn operating system is a collection of files that perform different functions. It is possible, over time, that one or more of these system files has changed or become corrupted. If this happens, the speed of your system may decrease. By using a utility called “System File Checking”, it will inspect these files and correct any problem it finds.
Scan for Viruses, Spyware and AdwareEvery Windows computer is near to viruses. Viruses are nasty little programs that cause both major and minor problems for users. Spyware and Adware are programs created by companies to find out more information about customers, so they can better market products to them. Usually these programs are not created for malicious purposes. Spyware and Adware can load into computer memory and slow it down.
Uninstall Unused ProgramsOver time, you may have accumulated programs on your computer that you do not use. When a program is installed, it creates connections between the program and the operating system. Even if you don’t use these programs, they can slow down your system. If you have the original program’s installation disk or file, removing programs will free up space on your computer speed up your system's performance.
Adjust Visual Effects for Better PerformanceWindows provides a number of interesting visual effects including animated windows and fading menus. If you do not have enough operating memory, these effects can slow down ypur computer. Adjusting or reducing visual effects can make a difference.
Don’t Automatically Start ProgramsPrograms use operating memory. Unless you always use these programs, you can keep them from loading at Windows startup and speed both the booting of your computer and its performance.
Defragment Hard Drive (After you have tried everything else) The more information and programs you have on your computer, the more it is likely that Windows has placed parts of the same file in different locations on your hard drive. It may do this for hundreds of files and programs, depending on how much space is available. Defragmenting the hard drive places all information for each file in one place. The result can be a faster computer experience.
Important Note: Before you even try this, backup all your work into a different computer, hard drive, CD or disk. Also, you should only do this if you have a reliable source of power for your computer. Doing this when there is a brown out or power problem in the neighborhood, is not a good idea. If a computer turns off while it is defragmenting a drive, it will create more problems than not defragmenting it in the first place.
Reinstall the Operating System and ProgramsIf you have done all the above steps and your computer does not become more responsive, you might consider reinstalling the operating system and programs. This is a scorched earth option - basically you backup all your data and user settings, wipe your hard drive clean and re-install the operating system with your original disks. Next, install all your favorite programs and restore all your data and user settings.
