Question Black Screen . Restart fixes problem

[m4n1ak]

Hello. So my problem started after upgrading my GPU , went from an GTX1080 to an RX 6800XT. First problem was that I had Black bars on half of the screen ,even in bios , after updating my GPU bios to latest version the black bars went away.

Now whenever I shut down my pc and then turning it on ,I can enter Bios no problem , Windows loads with the dots doing circles and theeeeeen I get a black screen ... Windows is responsive , tried windows+ctrl+shift+B , heard the beep , but the screen is still black , the monitor stays on ( doesnt go to standby , so its getting signal ). If I restart then then I can get into windows , no black screen.

could be your upgraded GPU + CPU need more power to run both.

It seems the recommended for that combo is an 850 or bigger, not a 750
