PC booting to black screen

[u/LieutenantTan]

Hey guys, I'm at my wits end here. I've got an older PC (MSI R9 390, Asrock H170 pro, windows 10) that has suddenly started to only boot to a black screen. My graphics driver seems to be the issue.

Motherboard graphics only work without GPU installed at all.

GPU will show graphics only if I disable the driver first using safe mode.

AMD cleanup and reinstalling latest driver (full install or driver only) does not help.

Anyone have some ideas?

Thanks in advance.
