Computer randomly shut down and won't turn back on

[siggi376]

Basically title says it all. I was just watching a video on youtube when my computejust shut down. I don't get any response from it when I try to turn it back on. I've left it for about 20 minutes and tried turning back on but nothing happens.

 

Specs:

i7-4790k

Corsair H100i

GTX 980Ti

Corsair AX860

MSI Z97 Gaming 5

Corsair Vengeance 16GB RAM

Samsung 250gb SSD

2TB Seagate HDD

Is your power supply fucked? Check it

Is your power supply fucked? Check it

 

How?

How?

Connect something of low value to it like a fan then jump the green cable to the black one and check the voltages.

 

Yellow=12v

Red=5v

Green=3v

Black=0v

 

if the power sully works then it's something else (most likely motherboard)

 

btw, re-seating everything is a good first step if you haven't already.

Switch off the PSU for a few seconds then switch it back on. Check your power cables are attached properly and clear the CMOS.

Ive done all that except clear CMOS, which I doubt will help me

check to see when you have your power supply on, if their is a light on the motherboard, it may be dead

It actually can, I would definitely recommend you try it
