PC shuts down after 10 seconds automatically.

Sorry to bring up old posts but i have the same thing i have changed everything the only constant is the motherboard

That being said i am sure it can be relatively easy to fix

I'm thinking a shot or maybe a dry joint on a capacitor is there anybody with some electronic experience that can point me in the right direction

Let me explain what happens:

Start-up 1: PC stays on for 40 seconds, dies while logging into user.
Start-up 2: PC stays on for 20 seconds, dies while booting.
Start-up 3: PC stays on for 10 seconds, dies while posting.
Start-up 4: PC stays on for 10 seconds, no signal to screen.
Start-up 5: PC stays on for 2 seconds and dies.

If I repeat after 10 minutes, it repeats from start-up 1.

Therefore, the issue is not software related. There is no over-heating on the CPU.

It is most-likely a power supply issue, or maybe the RAM. The pc must be about 5 years old....

I had the same symptoms on a aging PC. It turned out that the on button would make and then only break after a while. Q20 sorted the problem.
