go to www.google.com, find and download these free programs:
Spybot search and destroy
Cleanup!
Run them both, this will help get rid of most of the junk on your computer that is causing it to be slow.
Now Go to Start>Control Panel>Performance and Maintenance>Rearrange items on your hard disk....>click on Analyze and if it says you need to degrament, click on that as well.
Your computer can run slow for a number of reasons, but in my experience this will help the majority of people.
