I am installing a X8DAE motherboard into a 743TQ-R865B-SQ chassis. But there is no video output. If I remove all the memories, then I can get no-memory beeps. If I remove VGA card, I can get VGA error beeps. VGA card is known good because it can work on other motherboard. This is revision L chassis. Could this cause the issue?
Please check your USB cable. If your USB cable is plugged into the 1394 header, please unplug the cable.
