Ok, so I've been trying to build my first PC, but since I'm a noob I've had a hell of a time getting it right. My first mobo was defective, so I finally get a new one this week, only to find that I can't quite get it to work. This is the problem: when I hook it up to a power supply and turn on the power switch in the back, it turns on automatically for a few seconds, then goes into hibernate mode. The mobo led is on, but the fans, video card, processor fan all turn off after a few seconds. It shouldn't even be turning on at this point, so I think it's a wiring problem. But let me know. I'll post the specs shortly.
