The situation I am on is "unable to start". I have configured this new motherboard and connected all power cables. When I turn on, my board the LED's light up. However the CPU red light also glows but remains stable and stay running. The ati card fan runs at get 100% speed but the system won’t start at all. The PSU is 1200w, so I think that there is no shortage of power supply. What else could be cause a problem?
