I know I'm in way over my head here on this M3A78-EM! It's stripped to motherboard, PSU, and memory. Only the front panel wires are connected (and the 4-pin and PSU connector). Pressing the power button it starts CPU fan on, but no video. I tried a new PSU, DVI and VGA ports, checked CMOS and chassis jumper is default, different RAM, and tried a video card. With no video...I don't know any more! Any thoughts would be appreciated!
