I had my motherboard crap out a few weeks ago. Asus P4C 800E deluxe. The light on the board wouldnt turn on so I sent it back to Asus and they sent me a new one. I rebuilt my computer and tried to start it up. The light now turns on on the motherboard but I get no response from my computer. It wont turn on at all. Does anyone have any ideas on how to fix this?
