PC Spontaneously Shuts Down

My machine will shut down & sometimes reboot, sometimes the system stays off but the fans still run.

The CPU is not overheating, there is no problem w\ the RAM & there is nothing in the event viewer logs pertaining to this.

I cannot duplicate the problem; it has occurred while the machine was unattended.

OS: Win7 X64
Board: ASUS P5E5
Vid: Nvidia Geforce 9000 GT
PSU: Ultra 550w X2
CPU: Intel Core 2 Quad

Do you know if Windows Update could be the culprit? I know in Vista (not sure about 7) it could automatically restart after installing updates.
