Ok, here's my story... Recently I've begun getting a four beep audio warning and my computer powers down. Normally I can go for a few hours before this happens, but it's especially bad when I'm veiwing cutscenes in games. Seems like anytime my computer has to draw anything complex it just gives up. I'm running the Everest sensor program and it shows my cpu temp at 45C on average but occasionally it'll jump to 90C and then fall right back down. I've also recently installed CpuIdle and it doesn't sem to be bringing the temp down below 45C. I think it's an overheating issue but I can't be sure and was wondering if anyone could help me out. System Specs: AMD 2500 CPU (not overclocked w/ stock fan and heatsink) Gigabyte K7N400 Mobo 1.5GB RAM Radeon 9600XT Soundblaster Audigy 400W Allied PS 120mm Exhaust fan 80mm Intake fan Any help would be greatly appreciated, I'm beginning to go a bit batty over this.
