Just built the rig in my specs, onboard VGA works fine, but just a black screen when I install the GPU. (Screen is black but the monitor is not giving me a "no signal" message.) I have tried: different GPU different PSU different monitor correct source input selected on monitor tried DVI and HDMI cables triple-checked power connections to mobo, CPU, GPU (all secure, none reversed) primary display set in bios tried ram in A1/B1 and A2/B2 (currently in A2/B2 as per Asrock manual) removed battery, held power button, waited, reinstalled battery updated BIOS disabled intel VGA driver in Device Manager All CPU and RAM values at default. Other than the display issue the pc is running perfectly. Is there any reason I would have a black screen in BIOS due to not having drivers installed for the GPU? I've never had that happen before, but none of my previous builds had onboard VGA, so I don't know if that makes a difference.
