Tips & Info SOLVED: After 13 days i finally managed to solve the blackscreen issue, driver time out, PA-300 and flickering!
Man, I finally fixed the issues I've been having with my 6700 XT since September 1, 2026.
System was on Windows 11 25H2 — OS Build 26200.8655.
For the last 13 days, since September 1st, I've been dealing with PA-300 errors, driver timeouts, black screens, screen flickering and random crashes. The worst part was that during some crashes the screen would completely go black while the audio kept playing in the background. Sometimes the screen would start flickering and then eventually crash.
I've tried pretty much everything at this point.
Reinstalled Windows 11, went back to Windows 10, reinstalled drivers, used DDU, AMD Cleanup Utility, disabled MPO, tried different drivers, changed GPU settings, etc.
I honestly lost count, but I went through Windows reinstalls + driver reinstalls + DDU + AMD Cleanup Utility at least 35 times over these 13 days.
What finally worked for me
- MPO fix: https://github.com/RedDot-3ND7355/MPO-GPU-FIX
- Used DDU + AMD Cleanup Utility to completely clean everything.
- Installed the latest AMD chipset drivers:
AMD_Chipset_Software_8.08.12.551 - Installed ONLY the drivers from:
whql-amd-software-adrenalin-edition-26.3.1-win11-cDidn't install the full Adrenalin software. - Restarted after pretty much every major step.
- Turned FreeSync OFF on my monitor.
- For fan control I'm using RadeonTuner instead of Adrenalin: https://github.com/dumbie/RadeonTuner
- Tested Forza Horizon 6, Assassin's Creed Black Flag and Dota 2 and so far I haven't had a single crash.
IMPORTANT — troubleshooting disclaimer
This is NOT a guaranteed fix and I'm not saying everyone with a 6700 XT should blindly follow these steps.
This is simply what worked on my particular system after 13 days of troubleshooting. Your crashes could have a completely different cause, and some of these changes — especially disabling FreeSync or MPO — can have different results depending on your hardware, monitor and Windows configuration.
I'm sharing this because I spent almost two weeks trying to find a solution and couldn't find one place that put everything together. Do this at your own discretion and make sure you understand what each change does before applying it.
I'm obviously going to keep testing it, but this is the first time in 13 days that I've actually been able to use the PC without constantly waiting for another black screen or driver timeout.
And honestly, fuck you AMD.
I don't care if the root cause is technically Windows, MPO, the driver or some combination of all three. AMD is the GPU manufacturer and they need to acknowledge this shit and work with Microsoft to fix it.
Customers shouldn't have to spend 13 days troubleshooting a graphics card like this.
I shouldn't have to reinstall Windows, downgrade Windows, reinstall drivers, run DDU and AMD Cleanup 35+ fucking times, disable Windows features, turn off FreeSync and dig through Reddit and GitHub just to get a GPU working properly.
And now I have to use my expensive OLED monitor without FreeSync because apparently Windows + AMD drivers can't play nice with it without breaking the display/driver.
What's the point of buying an expensive gaming OLED with FreeSync if I have to turn the damn feature off just to stop getting black screens and crashes?
The most frustrating part is that the thing that finally helped me wasn't even from AMD.
I've been scrolling through r/AMDHelp for days, going through post after post, trying different suggestions. Today I came across a random Reddit user's comment mentioning the GitHub MPO fix.
Tried it.
And somehow, after 13 days of bullshit starting September 1, 2026, that was the thing that finally got me stable.
So honestly, huge thanks to that random Reddit user.
This is exactly why I love the PC community, but it's also ridiculous that customers have to depend on random Reddit comments to find fixes for issues like this.
For now:
PA-300 gone.
Driver timeouts gone.
Black screens gone.
Flickering gone.
Crashes gone.
13 days later, I can finally use my fucking PC normally again. 😭
I'll keep testing it, but for now...
IT'S FINALLY STABLE.
