I just built a PC using an Intel DP43TF motherboard and a Thermaltake 5oo watt power supply. When I press the power button the fans spin for about a second then stop. There is no video or POST. This motherboard is a replacement for one (same make and model) I returned to the vendor for the same problem. It behaves the same way with a different power supply, in the case or bare on the bench. A different motherboard in the same case works perfectly with either power supply. Is there something I'm missing or a quirk to this particular model of board? I find it hard to believe that two in a row have the exact same defect. Any suggestions for further troubleshooting would be greatly appreciated.
i have exact same problem
