I've got a new build and I'm getting no video and an odd POST. One long beep and three short beeps on a Gigabyte, which according to this means a "Graphic card error", but there is no graphics card. See video of the POSTing for yourself here. The motherboard has both VGA and HDMI, and I've tried having each one plugged in individually, as well as both plugged in. No video and the same post under all combinations. Any suggestions?
