i have a 1.8 ghz with 512 mb of ram, a radeon 7200 64mb ddr, and a 80Gb hard drive that has about 10Gb of space left. Theres another computer next to me that has half the ram and a geforce 2 with only 32mb of memory and probably a smaller hard drive with more free space. The lesser computer sometimes slows down but the other computer starts slowing down a lot when playing games and i can see the hard drive light coming on a lot and i've defragged the hard drive a bunch of times already. Anyone know of anything else i could try?

I also have norton's whole suite running in the background...do they slow things down?
