Help determining if my cpu is fried?

post #1 of 4
Thread Starter 
Hi everyone, I'm having a serious problem with my rig and I need some help.

My computer's cpu was running at 100C for about 10-20 seconds so I shut it off and came back. After that I got it back running at 30C for a couple minutes then I left it off because i had to do something.

I came back later and now the computer will only boot up for a split second then it just completely powers off.

I tried just about everything, the computer only stays on if I don't plug the 8 pin connector in to power the cpu, so I think the cpu is toast? Any other things I should check for?

I tried a new psu, and bare components, etc, nothing keeps it booted for more then 1-2 seconds except unplugging the cpu's power plug.

Sounds like a motherboard VRM failure
Though on this motherboard it's something I'd doubt to happen, and with the other info you gave I find it unlikely.... (i.e. you were away from home and the PC is turned off and it toasted itself!? no...)
You might want to try the CPU in another motherboard, IF you can

Hello, thanks for the reply. I am going to try and test my cpu in a friends computer tomorrow, and I will report back, although I am hoping it is the motherboard that is bad, as I want to upgrade to a new board anyway.

Ok, so i tested the cpu in my friends computer and it works fine. Looks like the motherboard does have vrm failure or something else wrong with it. What do you think?
