So my PC started crashing two days ago, but that was only under heavy load. Now it won't even boot, however when I remove my GPU it runs fine. PSU is definitely the main suspect but I don't wan to spend a bunch of money on a new one if it's something else that causing it. So I was wondering if my PCIe slot on the motherboard could be faulty or something like that, I really have no clue about troubleshooting when it comes to motherboards. RAM is not at fault, already tested both sticks, first one by one and then both at the same time with Memtest86 and it found 0 errors.
