You have had your PC for a while, and lately you have noticed it slowing down. If you have never run any of the include Windows diagnostics, you may be causing your own problem inadvertently. These three little tools can help you bring your machine back up to speed in no time at all.
Defrag the Computer
If it has been some time since you ran a defragmentation of your hard drive, or worse, you never ran one, this is the time to do it. Defragmenting a drive helps it retrieve data more efficiently and quickly.
When you save, your computer dumps files anywhere there is room on the hard drive. Later, when it goes to retrieve them, it has to pull them together from all over the place. If you run the defragmenter, it will pull common files together reducing the time it takes to search for them later.
This diagnostic can take some time if you have a very large or very full hard drive. It is best to “set it and forget it.” Select a time and day each week that you are most unlikely to be using your computer and let your PC defrag to its heart’s content without it affecting you at all. This will help speed up data retrieval.
Try a Scandisk
If you have started to see error messages when you boot up and shut down, you have probably developed some problems in the operating system. It is normal for these things to happen over the life of a computer, but running scandisk will allow your PC to search out the errors and find solutions before they become critical.
There are times when scandisk can’t run because you are using certain programs. If that is the case, it will offer to run itself later when you shut down the computer. Let it do so. A clean, fully functional operating system is faster.
Backup
Truthfully, backing up your files won’t do much to speed up your computer unless you remove files you aren’t using regularly. Things like photos take up a ton of space on a hard drive. When your hard drive gets too full, it runs slowly. By backing up data to another drive, CD, or an external drive, you speed up your system.
Pair Up Windows Diagnostics with Registry Cleaner
A registry cleaner is a utility you can download in a few minutes that takes care of cleaning up your hard drive for you. It searches out errors in the operating system and fixes them if possible. Download a registry cleaner along with running Windows Diagnostics as a part of regular maintenance.

I’m sure many of you would want to start 2009 with a clean slate. May I then suggest that you start the new year with a clean and secure PC. There are many ways by which you could accomplish this.
