Possible sources of the problem;

1. Weak / overheating power supply
2. Overheating CPU
3. Bad RAM module
4. weak CMOS battery
5. Overheating chipset

I would start by replacing the CPU fan, and checking the power supply.

Then, I would remove and reseat the RAM and all plug-in cards.

One thing to check before you go diving into your machine is the power management settings.

On some computers, when power management is enabled, the voltage is reduced so much that the machine treats it like a power failure, and switches off. By this time, of course, because the power was never actually turned off, it restarts.

Hope this helps

as stated.....BEFORE you go changing components...... make a visual check to ensure your CPU fan is indeed working. Then, if your board has SoftMenu bios,or bios enabled fan/temp control, you can set the temps 1 degree higher[staying within mfg specs.]and see if it is just a temp alert resetting your system. [You could also utilize Dr. Hardware} Hope this is of some help ... H :-)
