My home PC runs perfectly fine when browsing the net, word processing and watching videos. But when it comes to playing some graphically intensive games it then starts beeping at around 20 second intervals at me. I've noticed that at each beep there is a very quick screen flicker. The actual game still runs smoothly, no slowdown or anything.
ATI Radeon x1950 Pro 256MB
Intel Core 2 Duo 6320
PC Case has 2 fans
Idle temp of Gfx card 59C & latest drivers
Is there anyway of turning the beeping off? If its due to overheating is there anyway of increasing the threshold?
