Ran into an issue today when booting my pc, i started it all was fine then it randomly turned off, no BSOD or anything just turned off completely, go to turn it back on, front fans light up i hear the PSU kick on then a second later it turns off, then i finally got it back on not sure how but it turned on worked fine went to open youtube and it turned off now won't turn back on. (doing the same thing as before) not entirely sure how to go about testing my PSU being as all the wires are black because i was already thinking of using a paper clip. PSU is an EVGA 750G3
