well about a week ago i got home and put my arctic silver on my cpu and then installed the fan and well i forgot to plug the fan in. the cpu got really hot 77 celcius and i turned off the pc then i took off the fan. it was soo daamn hot. anyways i waited came back then i plugged it in and everything was fine. installed windows over again, then today while playing midnight club 2 online with my cuzin tge joystick just started going haywire, then it just restarted instantly, and then opened windows i checked the temps all fine. then it was acting like a pentium2 taking sooo long for everything. then restarted again, then acted like its suppose to. and restarted again. so is the cpu done? should i buy another one?
