Is your gpu connected to the mobo firmly are the fans running?Bro btw which interface are you using DVI,HDMI or VGA?The cable could e the problem too.BTW use zotac usb maker and install win8 using it onto a 4GB flash drive.BTW can you check if you can get to the bios setup?
I've tried several HDMI and VGA cables. Fan is running on GPU and CPU. I'm not getting any picture, so I can't see BIOS at all. No USB ports appear to be functional, as I can't connect and use a keyboard. Only time it reacted was when i put a flash drive in the flashback bios port, but that did not work either. No beep error message either, so I suspect the problem may be the mobo?
