Last night while playing a casual game of LoL (not hardware demanding), my computer just entirely shut down and wouldn't boot back up. My PSU (corsair TX650M) would not boot whenever the 2 pci e cables were attached to my graphics card (msi 7950 oc) I stuck a paper clip in the green and black sockets of the ATX power connector when everything was unplugged and the fan spun. Following that i plugged everything in (except the GPU) and the computer started up fine. I'm currently using integrated intel graphics. Is this a PSU problem or a gpu problem? Thanks for all the help.
