the best way to speed up your comp. is reformat it. it takes a lot of time to reinstall everything but it's always nice having a fresh start, if you don't want to do all that work, then run disk cleanup and defrag and other utilities. also if you have a chance at getting norton systemworks, do so. It has an excellent windows cleanup program. another thing to look at is your cpu temp. if it seems high as in the 60's you should try cleaning your heatsink and fan. i noticed a speed loss with my old cpu cooler after it got dusty. it's something to keep in mind.
