Computer shuts down after a one-two seconds


A few days ago, I built a new Computer. It booted and
everything was fine. I also installed Windows 8 and drivers
to the motherboard and graphics card.

But when I was rebooting my pc, the CPU has suddenly reached 80
degrees, and few seconds later it turned itself of.

I waited some hours before I tried to start the computer again.
But it never came to the BIOS, only the fans where spinning.
So I tried to turn off the computer, but it didn't work, so I had
to turn ofF the switch on my PSU manually.

After a few seconds, I turned the PSU switch back on again.
The motherboards lights turned on, but when I pushed the start button,
it turned itself off in one second or two.

The PSU gives a clicking sound when it turns itself of.

I've tried to:
- Remove all components and cables and reinsert them.
- Restart the CMOS
- Updating BIOS
- Reinsert the motherboards battery
- try only with the motherboard, CPU, RAM
- use another CPU (same model)

But all these attempts made no improvement.

The computer components are:

Motherboard: Asus Rampage IV Formula
CPU: Intel 3930K
PSU: Corsair HX850
CPU-Cooler: Corsair H110
RAM: Corsair Dominator Platinum 1866MHz 16GB
GPU: Asus Geforce GTX690

Will appreciate all help!

  1. Hi, I guess that the CPU cooler doesn't work.
    Try installing a different (stock if existent) one and test again. Clean the old paste and reapply new one. Hopefully the CPU is OK.
  2. I've tried to use a different CPU-cooler, it didn't help.

    A thing I forgot to mention, is that the Motherboard has a Debug LED, which seems to
    show error code 19 before it turns itself off. I'm not entirely sure, since it turns itself
    of extremely quick, but I think it shows 19.
  3. faulty mobo, like mi mine .. i send back to ASUS .. my computer can turn on need empty electricity during 24 hours , after that can on again, but if i forget unplug power AC from PSU my PC won't turn on .. send it back
  4. I would RMA the CPU too.
