This guide will give you a few tips to speeding up your computer and improving its performance.

Instructions
First, check to make sure that you hard drive is not almost full. Having some extra space can improve your PC's load times and running speed. I suggest having at least 20-30% of your hard drive free at all times. Having too many programs and files can really slow down your start up time.

Spyware and Adware can have a detrimental effect on computer speed. There are free ways available online to download software that deletes spyware and adware from your computer. It is advisable to run spyware and adware checks at least once a week, as malware can easily become a problem fast.

If you're really having no luck with the above steps, it may be time to invest in a RAM upgrade. RAM can be purchased at any store like BestBuy and will give your computer more memory to deal with when running multiple programs. These stores will also install it professionaly if you don't feel comfortable with PC repair, but there are guides available on eHow for RAM upgrades.
