Typically caused by one of two potential problems:

1. Thermal overload - safety circuit shuts system down

2. Faulty or underpowered PSU.

I agree with Ted. It is likely a Power Supply problem. When you are doing something that creates a load on the computer stressing the components when the components don't get enough juice. The computer resets of turns of. So get a different PSU.

Why does everyone always blame the Motherboard?

You can't go by your CPU fan. Get a $12 PSU tester at circuit city and check the PSU. preferably one that allows you to use a voltmeter. If you don't have one of those, get one.

if you're not comfortable or unsure, just replace the PSU.
