Hey guys, my friend and I were facetiming because he is having the problem of his PC "Turning on Then Immediately Off" as he stated. I had this problem before when installing a psu, what i did was unplugged the 24 pin and the 4 pin mobo connectors and then i plugged it back in. That worked for me, so I told my friend to do it. He tried it and it didnt work (he did not buy a new psu or anything btw, this just randomly happened) So I told him to check the cable, the psu, and still nothing. Since it is my friends build I don't know exactly what he has but its along the lines of an Intel Core i7-4790K and a 1660 , or the TI again im not 100% sure. Also its a prebuilt, so maybe a bad psu? but I have no clue. Let me know what you think, thanks
