Hey guys. Sometimes when I'm using my computer the internal speaker starts going "EEEE-RRRR-EEEE-RRRR-EEEE-RRRR" and I don't know why. It happens mostly when I'm playing Thief 2, but the other day it happened when I was using Microsoft Excel. When I close everything it stops after a while. There's nothing in Task Manager or anything like that to indicate a problem. It just makes that noise. I think it's because the CPU is overheating, but I can't tell for sure. I have an Intel Pentium 3, and the computer is getting old. So three things: - What's causing the computer to make the noise? - How can I monitor my CPU's temperature? - If the CPU is on its way out, can I replace it without getting a new motherboard? In the meantime I'll check a few things with Everest. Thanks!
