Brother of mine ordered a PC and wanted me to build it. Couldn't get it to turn on at all today so I assumed the PS was DOA. Tried it on my PC and ran fine. Unhooked the GFX and tried turning it on. Wasn't that either. So I finally decided the MOBO was broke and told him I would send it in tomorrow. He came here after work and wanted to try one more time. Hooked the two power connectors to the MOBO. Hooked power switch up, it turned on. Unhooked it, plugged everything back in after putting it in the case. Won't turn on. Unplugged it and re-hooked the 2 power connectors. It turned on. What the fuck is the problem?
