Your best options for improving overall performance are to track down specific driver updates (for video card, sound card, etc..), to remove any programs off your hard drive that you no longer use, and to use virus & other system scan utilities to remove excess code/commands deposited by every program ever installed onto your computer.

Thanks Thermo and Katchoo, that sounds like wise advise. I was curious, though, Katchoo, did you have any specific scan utilities in mind? I use Norton Antivirus and SystemWorks regularly. Do you know of anything in addition to those that might be useful?
