I got a laptop that has always been fine, I reinstalled win xp pro on it and now it runs liek realyl fast for liek 15 minutes and then the fan comes on and is really loud, then my computer just gose liek dead slow. How can this be? I need some quick help fast, I need this laptop for work. Any help is greaty appericaited -Shane P4 Mobile 1.6 GHz EDIT My Guess:? Im guessing that either the CPU is getting really hot for soem reason, or the CPu thinks it getting really hot. Witch is turning the fans on full blast and Lowering the CPU Speed? To cool it down?
