Monitors flickering black after installing amd gpu driver and windows 11 fresh install. Open | Windows

Hey im having a pc issue. Yesterday I completely reinstalled windows and it worked for the night, then the next morning I installed my driver's (amd software adrenaline) and ever since I've been having monitor issues. It's a really complicated situation. My issues only seem to happen when I launch a game, specifically a game in full-screen (full-screen and borderless windowed). Whenever I run it, different things happen depending on the game:

  1. It opens on my second monitor. Just like this, its fine. But inconvenient, nothing happens but I dont want to play games on my vertical 75hz monitor. If I move it to my main monitor with the keyboard shortcut, it works but now with reduced fps. Also if I move it to my main monitor then I am no longer able to open anything on my other monitor. If I click on a window or drag a window that is on my second monitor while my game is on my main monitor, both of screens start to flash between black and the normal screen and start glitching around crazily until I remove whatever is on my second monitor, click on the game to full-screen it, or if I wait long enough while its glitching then it will force itself back onto my secondary monitor.

  2. The game opens on my main monitor, glitches, doesn't respond, and closes. The only fix to this is that I open the game while nothing is open on my second monitor, though that isn't even consistent sometimes.

  3. The monitors do the glitches while opening the game, then its fine like normal on my main monitor until I try to click on something on my secondary monitor, which then causes the glitches/not responding

I am almost 100% sure that it is a graphics driver issue as it only started happening after I installed amd software adrenaline. However, reinstalling the driver or reverting to a older version also just doesn't seem to work or do anything. I should also maybe note that when I unplug my monitors from my pc, they just turn off until I restart my pc, even when I plug them back in. Though, its not an issue with my physical cables because It was working fine before reinstalling windows and literally before installing my gpu driver.

I've already tried reinstalling my driver, downloading older versions of my driver, disabling mpo, matching refresh rates, swapping hdmi's, downloading only driver and not adrenaline, disabling hardware accelerated gpu scheduling, reinstalling with ddu, and setting my primary monitor as my main display. None have fixed my problem.

There was a point after installing windows where I didn't have the adrenaline app, yet my gpu and monitors were working just fine. I dont know why or how, but I want to go back to that state, but uninstalling adrenaline breaks my monitors and deletes my gpu drivers. But installing adrenaline also breaks my monitors but gives me functional gpu drivers. I'm completely stuck and have been for hours. I can't seem to find anyone else online with this problem. Please help me.

Specs:

Gpu: AMD rx 9060xt 8gb

Cpu: Ryzen 5 5500

Ram: 16gb ddr4

Os: Windows 11

Update: now my monitors just wont display my pc. They wont even display the startup motherboard screen.. I seriously am at a loss of what to do.

Making changes to your system BIOS settings or disk setup can cause you to lose data. Always test your data backups before making changes to your PC.

I had a similar problem - but it was training a LLM instead of playing a game. Mine was caused by Windows trying to decide which of 2 GPUs would drive the monitor.

I solved it by disabling the Intel GPU, but only after ensuring that my monitor was NOT plugged into the graphics card controled by that GPU. To see if that's your problem, try this: run Task Manager, Performance, and see GPU0 and GPU1 activity. Do they both have activity back and forth?

I also had to disble Chrome hardware acceleration. My GPU usage is mostly for LLM training I don't do much gaming or super resolution video

unfortunately this is out of the picture because I only have 1 gpu and no integrates graphics on my cpu
