I recently built my own pc (like 10 minutes ago) and after it not turning on because the Power switch was in the wrong front panel socket on the motherboard, I finally turn it on and about 10 ish seconds later it powers down, then starts up automatically and would probably do that continuously, all the wires are connected and the GPU, CPU, psu seem to be working, my ideas involve the motherboard or possibly lack of power from the psu, I have a CS650M psu, with a Inno3d GTX 780, gigabyte Z87X-DH3, i7 4770 and stock cooler, 16gb Ram, 1tb hdd and 120gb 840 evo ssd and a Corsair 500r, any help is welcomed
