I've had my pc for a while, and recently I had a "System Disk Error" problem, which turned out to be a loose connection.
However, NOW whenever i put my pc under stress by playing a game (CS:Source or FarCry for example), the pc itself (not the speakers) makes a continuous beeping noise!
It is the same tone, and each beep is about 2 seconds apart, then if i leave it for a while it freezes and restarts itself...
I'm guessing overheating of some kind..? any help/ideas would be very much appreciated! =)
