Black screen after windows boot, no cursor

[RovakX]

Problem: After windows boots (after windows 10 logo), but before the login screen appears, my monitors go black, no cursor is visible.

 

I run a dual boot config, twice windows 10 (64 bit) one for personal use and one strictly for work, installed on different physical SSD's, not partitions. The problem only occurs when booting to the personal drive, the other one works just fine.

Problems started after a windows update on my personal drive a while ago. In the midst of the update, the PC had to reboot, and booted to the wrong drive (Which is weird, the personal drive is set as primary boot drive). I immediately rebooted back to my personal drive, but only got a black screen. Rebooting from there results in a black screen again. Rebooting over and over again doesn't change anything, windows recovery never kicks in.
 

The PC can boot into safe mode (F8 method, luckily boots in safe mode on the right drive). (only my secondary monitor works in that case, I don't know if this is normal?)

From safe mode, no windows updates were available, so I guess the update did install completely?

So, my next thought was this might be a GPU driver issue, no updates available though, I used DDU to uninstall and reinstall drivers. I got the latest driver from AMD's website.

The problem almost seemed fixed at first, the PC reboots during the driver uninstall/installation proces, back in regular boot mode, and then works just fine, until I reboot again. I can repeat this proces of booting to safe mode, uninstalling the GPU drivers reinstalling them and then having everything working, for exactly 1 boot. 

I tried installing the optional newer version, or an older version of the drivers (Way back to 17.11.1, but the problems persist.

I also checked if windows is up to date, checked other driver updates, I checked for malware, I cleaned out dust in my system, ...

 

I tried unplugging the GPU and running on integrated graphics with just one monitor. (AMD A8 7600 APU w/ Radeon R7 integrated graphics) Still boots to black screen.

 

Whenever I want I can boot to the work drive, and everything works fine there, the GPU driver installed there is 18.3.3.

Which makes me believe it is not a Hardware problem.

 

Any recommendations to try next? I'm thinking of reinstalling windows at this point...
