I built a PC today and when I turn it on, it stays powered on for a few seconds and then powers off by itself. After three seconds of being powered off, it powers back on by itself. During this entire process the screen remains blank. Nothing has ever come up. I've verified that it's not a problem with my monitor. I've verified that I made the appropriate connections to the motherboard (the socket near the CPU, the really big socket, and the sockets on the graphics card itself. The lights come on, all of the fans come on, I can open and shut the DVD player, but the screen is always blank.
