Voltage Problem?

[sand1070]

Hello,
I've got a voltage problem that I can't figure out.
I have an ASUS A7V600 Motherboard and in the hardware monitoring section says that I keep getting a power overage in my +12v.
I've ran the ASUS Probe program that came with the mobo and it says that my +12v is jumping around. The two voltages that it says the most are 12.8v & 13.184v.
My PC has been shutting down on its own do to this.
I tried a new power supply which lasted for about 2 to 3 weeks and it died.
What would cause this?
Any and all help would be greatly appreciated.

Multimeter. Software/bios readings are always off. But since it's shutting down there definetely seems to be a problem. If it's more than one psu then I'd look at the mobo or one of your drives.

What PSU did you get to replace it? If you replace a crap PSU with another crap PSU, you will not have solved your problems...

yeha - you can't trust software readings... overvolting is not good for your hardware...

I replaced the colorsit 480w psu that came with my case with an xpower 450 psu.
The xpower one is the one that died after 2 to 3 weeks.
I haven't had a chance to get another psu yet.
I'll let you know when I do and what happens with it.
