A certain member of my family had moved my comp around a lot, and silly me forgot to look inside and check everything out, so as I'm sittin at the machine today, it just turned off, out of nowhere. I checked all the plugs, then opened the case to find my HSF dangling off the socket (XP 1600+ on a K5s7a). I replaced the hsf, and the computer booted, but would not load windows, turning off and restarting before the splash screen even hit. I tried again a few hours later and was able to get into windows, but it immediately shut down as soon as windows was nearing the end of loading. Did I fry my cpu?
