PC randomly turns off

[Flatoutnos]

So my pc randomly turns off for no reason. It's happened at idle and while under load and anywhere from as soon as I turn my pc on to 18 hours after its on. When it turns off I have to flip the switch on the back of the power supply a few times before it will actually turn on again and when it shuts off for no reason, my led lights and motherboard lights are on sill. I'm thinking it could be the power supply but could it be the motherboard instead or even something else? 

 

motherboard= z97-a

psu= cx750m

Do you have a spare power supply to test with?

Sounds like a PSU issue. Try unplugging all devices except VGA card adapter then turn on the PC. 

Check that the 20+4 pin connector is firmly in place, along with the 4 pin CPU connector and others.

 

Best option, test with another power supply.
