ok, im gonna pretend that i didnt hear that. i thought it was a different prob, till i did some research on it, in ur other thread. it might be ur fan sensor going out, but then again, yes u might wanna reinstall the os, because, hear me out, if u have spyware/viruses it will slow ur pc down on the net. the fan could be going out....first, before u go around and start calling us morons and whatever(ok ive cooled off now) run hijackthis(sounds suspicious, but nope, ittl tell us if u have spyware or viruses) and also run spybot search and destroy...after that, get speedfan and check ur temps and fan speeds, and see if anythings wrong. and we wernt making fun of u, were just trying to tell ya to stick to one thread. everybody cooled off now?
