As im playing PUBG one day my PC decides to turn completely off, so i reboot my PC and try again, same issue occurs its happened on World of Tanks and PUBG both, nothing else seems to make my PC shut off, Ive been told its a Heat issue, Ive been told its a PSU and ive been told its a MotherBoard issue, cant be a heat issue "At least from what i can tell" as i have several fans in my case and i even have a box fan blowing into it cause i thought heat was the cause, PSU ive changed my PSU from the 750M to the 500B and i also changed my GPU as i thought my GPU might be power hungry. Im not really good with PCs so im hoping somebody here can have me stress my pc or something to help me figure this thing out
