My comp won't boot after plugging in my 2x2 plug to the mobo. I press the power button fans start spinning and LEDs come on but only for literally 1 second. Without the 2x2 plug in everything runs, but obviously that doesn't help me since the 2x2 powers the CPU. I've already reseated everything within the PC and even had my CPU replaced under warranty thinking that my have been the problem. Any ideas what may be going wrong?
