No VGA Detected or Fail

[0wen]

I recently upgraded my PC to include an i5 8600k with an MSI z370 gaming plus.

When I power the PC on the debug light on the motherboard says that no VGA detected or fail. However this can't be true as the monitor receives a signal (only a black screen though) but if left for around 5 mins the debug light goes off and the PC begins to boot into windows only very very slowly considering its installed on an NVMe SSD. Not only is it slow to boot the peripherals all lose power temporarily while windows loads and I have to wait for them to come back on before I can use the PC. After the PC is fully loaded everything works like a dream so I am at a loss.

Are you using the video outputs on the motherboard rear I/O or from the GPU?
