I have had a problem with my computer restarting at random for awhile now, I have
1)ran memtest86 overnight and while at work for 14 passes with no errors.
2)Checked the temperatures for overheating with speedfan, system and cpu under 34c
3) Formated hard drive and re-installed windows

my suspicion is that it may be the power supply, what do I look for when looking at wattage in the bios? And here is my system information from cpu-z (not all, its very long, please ask if more info is needed.)

Any help would be greatly appreciated, especially on where to look to see if power supply is indeed failing/bad.

What are the voltages ?

I suspect too. That its a BAD psu .Eventhough you dont have any load.

Do you have a spare PSU to try it out ? Maybe borrow it ?

Thanks for the response, I took your advice and managed to borrow a PSU, been running on it now and still am, no problems. Will be taking it in to get it exchanged tomorrow if it doesn't restart overnight. The Voltages actually where fine under the BIOS.

Recent update, figured out how to use my multimeter and only one of the pins for the motherboard power was faulty, thus it being fine for awhile. Thank you for you reply.
