I built my own system about a year ago and now have a serious problem with it. I came home to find it powered off. I pressed the power button on the front of the system and the fans start to turn, and then it stops. The power light is lit up on the motherboard, and goes off when I unplug the system, but when I turn it on the fans start and then stop and nothing. I replaced the power supply with a new one and when I turned it, I experienced the same exact thing!! What do I do next? Any help would be greatly appreciated. Thanks, Nick
