Default Computer restarts randomly

Hey guys,
My computer keeps on restarting at random periods and I have no idea why it does that.
Sometimes it may restart while on the startup screen, while i execute something or while i look through the files on the computer.
Here are the things that I've tried to do:
1) Check the RAM with memtest. No errors.
2) Installed a temperature program to check if it's overheating. It had a decent temperature of about 34 degrees.
3) Reformatted the hard drive, but it still restarts.

Here are the computer specs:

I deleted some of the specs because it went up to 150+ pages of info, and I don't think they're needed.
If you need any other information, please let me know.


Thanks,
Matt

What about your power supply? Don't see any specs on it.

Default Re: Computer restarts randomly

Is this what you're looking for? I found this in the BIOS.

Processor Zone Temperature: 36C/ 98F
System Zone 1 Temperature: 27C/ 80F
System Zone 2 Temperature: 27C/80F

The temperatures move up and down by one if that matters.

Here are the Voltages:
+1.5Vin 1.454V
Vccp 1.470V
+3.3Vin 3.017V
+5Vin 5.263V
+12Vin 12.125V

The brand is PowMax and output wattage is 400V.

I would suspect that power supply. A failing power supply will cause random restarts. Just judging from the numbers you posted, the +5v looks like its pushing the tolerance of atx specs. Do you have another power supply you could throw in and see if problems persist?

Oh well, I have a 250W power supply in another computer.
But I thought it'd be too weak.

I'm thinking of just buying a 430W-500W power supply.
