A couple days ago, I took my computer to school to work on it with the stuff they have there and to hook it up on their T1, and when I took it home, I booted it up, and everything was fine. Until it shut down out of the blue. So I rebooted and went into bios, and it said my CPU was running at 75 degrees celsius!!! As soon as I saw this I shut it down, and it seemed the CPU fan and heatsink's plug had wiggled free, and now it is running at 39 cels. I just hope that I didn't damage anything permanently . . .
