I have an Abit SG-80 motherboard with a P4 524 CPU. For the last week I have been getting a random beep coming from the internal speaker during use. When it beeps, the system pauses for a second or two. Sometime it will do two or three times, sometimes just once. Can this be caused by my CPU getting too hot? BIOS states it is running about 73?C. I reloaded everything thinking it may be software related but I guess not. Any ideas?
