Hi, I just built a PC using this motherboard, 850W PSU, 32GB DDR3 RAM - I cannot get anywhere, double checked all connections - it switches on, fans go on AMD chip and graphics card, but no video output. I put in another video card I know works (and still does now its back in *this* PC) and same thing. KBD lights don't light on power up, caps lock doesn't function, tried a different (non-usb) keyboard, nothing. Pressed delete key repeatedly on power up, still no video signal. Tried both VGA and Digital outputs on both graphics cards. Hard disk lights and flashes every 10-15 seconds, and CD player ejects and lights up when you put a CD in. Arrrggghh! Can anyone please help me?? Thanks in advance Jack.
