I have a crosshair vii hero motherboard. I hooked everything up on my motherboard box and everything is working. lights are on, fans spinning. Nothing on the monitor though even though my gpu is hooked up and my display port cable is in it. It keeps getting the code ‘02’ while booting up. I honestly don’t know what’s wrong. I have just flashed the bios with the new driver for the 3000 series chips and I don’t have a windows installed on my hard drive yet.
