Re: holy shit help me
Possible virus perhaps? Corrupted files. Could be memory, but that's the last thing I would look at. Usually if it's RAM problem, it wouldn't restart like that. Then again, I've seen stranger things. Try taking out a stick to see what happens. If still the same, try repairing Windows by popping in the Windows XP CD.
On my PC, when the CPU gets hot (trust me, it got there), it simply shuts down. Doesn't restart.
