Hi, I just finished building my new PC with a Asus Maximus Vii Gene and a Asus 780Cu. Initially everything worked fine then today for some reason the PC wont boot and there is no signal coming onto the screen however when I plugged the HDMI into the MB it works fine. Very frustrated. And when I entered the BIOS the graphics card does not seem to be detected because when I go into the graphics card information nothing came up.
