Intermittent Reboot

Occasionally within 3 - 4 minutes after I turn on my PC, I hear a click, the
monitor goes dark and the system reboots. I suspect an intermittent in the
power supply, but I would like other opinions before I go out and buy a new
power supply.

Thanks,

open event viewer & get more details,if you get that far...

Another possibility is a failing capacitor on the motherboard. I
recently replaced a motherboard that would suddenly reboot without any
warning or error message in the log. Inspecting the motherboard showed
a capacitor bulging. I got a replacement board under warranty and have
had no further problems with the computer.

There is a picture of a bulging capacitor here. In this example, they
would be on the motherboard, near the processor area. A motherboard in
bad shape like this, could be rebooting itself.
