Hello,

Sorry this message is short on details, but just a quick, general question.

I've got a system running an AMD Athalon 64 which has started randomly shutting down. I've set it create a minidump file and automatically restart, but this does not happen.

I first suspected the power supply (a Cooler Master), and replaced it last week, but the crashes continue.

I downloaded a temperature monitoring app, and disovered that overnight my CPU had gone over 100C. Just checked, and the CPU fan seem to be barely turning.

Is this crash with no warning typical with an overheated CPU?

Thanks,
Brian

I suspect that you are right. I opened the case with the power on, and the CPU fan was turning much slower than its rated 2000 rpm. I'm going to try replacing the fan (its a 120 mm, 3-wire fan) and see what happens.

Thanks for your reply,
Brian
