I was using my pc normally when the screen suddenly lost signal and fans went to full speed. I could still hear the sound from the video I was watching, but I also heard the windows connecting and disconnecting sound (the sound that plays when you connect and disconnect a usb device). After a couple of seconds the computer turned off and now nothing happens when i press the power button.

Specs:
Cpu: i7-4930k
Gpu: EVGA GeForce GTX 780 Ti SC
Mb: Asus x79
Psu: XFX XXX Proseries 750w
Ram: Crucial ddr3 ballistix 16gb
 
Solution
Hello... 5) MOMENTARLY touch/short the Psw pins @J1 for a test without the case SW plugged in there next.
The circuit comes form the PS... in that BIG MB Connector on the MB... though the MB traces... to those two pins B )
