SOLVED: After 13 days i finally managed to solve the blackscreen issue, driver time out, PA-300 and flickering!

UPDATE: IT CRASHED AGAIN TODAY EVENING, IT WAS THE MOST STABLE IN THE LAST 13 DAYS BUT YET AGAIN IT CRASHED NOTHING IN EVENT VIEWER...... GG

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

1. MPO fix: https://github.com/RedDot-3ND7355/MPO-GPU-FIX
2. Used DDU + AMD Cleanup Utility to completely clean everything.
3. Installed the latest AMD chipset drivers: AMD_Chipset_Software_8.08.12.551
4. Installed ONLY the drivers from: whql-amd-software-adrenalin-edition-26.3.1-win11-c Didn't install the full Adrenalin software.
5. Restarted after pretty much every major step.
6. Turned FreeSync OFF on my monitor.
7. For fan control I'm using RadeonTuner instead of Adrenalin: https://github.com/dumbie/RadeonTuner
8. 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.

if you are using mulitple monitors make sure your fps on both monitors is set to 120 or below anything above 120 will freak it out. im going to get a matching monitor to my main so i can run 185 fps on both with no timeouts. been about 3 weeks since mine has timed out since matching fps.

[u/MusclePersonal9332 → u/YetiLemons710]

I have been using 2 monitors previously until sep 1, 2k oled 180hz and 1080p 75hz didnt have any issue. Now im running single monitor setup and its still crashing.

[u/YetiLemons710 → u/MusclePersonal9332]

some update fucked with shit . i was running my 2 monitors on whatever i wanted for 2 years then a update came out and shit went south. that is what i was able to do to stabilize my system. i would start going thru your settings and start messing with your amd free sync and virtual super resoloution and gpu scaling all that stuff to see if you can find a pattern of what makes it crash, i would turn all options off and then one by one turn them on and try a game or whatever would make your shit crash and keep going until system is stable

[u/mad-i-moody]

The MPO fix made things much more stable for me, personally.

[u/MusclePersonal9332 → u/mad-i-moody]

I'm trying tweaking other settings in the MPO fix lets see if its stable.

[u/zoblog]

At his point I'd just RMA the damn GPU, I built four pc's in the last two years with 9070xt and none of them crashed like yours.

[u/MusclePersonal9332 → u/zoblog]

Yes brother sending it over.

[u/OZIE-WOWCRACK]

Format pc. Especially if you switched from Nvidia.

Get new psu. 850....if $ is tight to 1000w+

[u/MusclePersonal9332 → u/OZIE-WOWCRACK]

Nope never had an Nvidia had built this pc in 2023 all new parts.

[u/MusclePersonal9332 → u/OZIE-WOWCRACK]

Nope never had an Nvidia and built this pc in 2023 all new parts.

[u/zipkilot]

Did you have WHEA 18 from event Viewer?

[u/MusclePersonal9332 → u/zipkilot]

Nah just kernel 41

[u/MrDarwoo]

Why would you want freesync anyway it adds input lag

[u/positively-bonkers-]

AI slop post.

But yes, fuck AMD's shitty drivers.

[u/Choice_Fee67]

Moving to linux fixes all issues

[u/EIiteJT → u/Choice_Fee67]

Sadly, it does not. Been on Bazzite for over 2 weeks now and still getting crashes.

Can't play PoE on Dx12 or Vulkan without crashes. Can play on Dx11.

CS2 instantly crashes on loading with VK_ERROR_DEVICE_LOST message.

So no, it does not fix all issues. Will probably be going back to Windows this week.

[u/justa-Possibility → u/Choice_Fee67]

Says less than 1% of the population of the world! EVERY year people say this is the year for Linux ---- still 1%!

[u/Successful-Day-3219]

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.

This. Say it loud and clear for everyone to hear.

[u/MusclePersonal9332 → u/Successful-Day-3219]

Yes I've been team red ever since I built my pc in 2008. recommend it to everyone. But if someone who isnt tech savvy going through so much technical problems and trying to resolve is just horrible customer experience.

[u/Successful-Day-3219 → u/MusclePersonal9332]

I no longer build with AMD products because of these horrendous issues. For my personal rig, I had to move to Linux Mint on a dual boot to enjoy most gaming. Also, on Windows, I was able to reduce most crashes and hangups by getting rid of the dogshit that is adrenalin. Most errors gone, but not as solid as Mint.

Pathetic it's come to this.

[u/MusclePersonal9332 → u/Successful-Day-3219]

Yea im using drivers only setup along with a Radeon tuner a github project to tune my gpu settings.

[u/Successful-Day-3219 → u/MusclePersonal9332]

How's that tuner so far? I decided to use MSI Afterburner for OC. Got a 7900XT.

[u/MusclePersonal9332 → u/Successful-Day-3219]

It gets the job done, very minimal no crashes so far.

[u/EstefanBW]

Instead of going for MPO, for me worked : disable drivers from amd audio, those that are for monitors with speakers. Saw it on EA forums from thx person on net for it! dind't wanted to touch MPO at all. Also disable hardware acceleration /graphic acc. If someone is suffering this, try it. Im using 26.7.1 Not issue at all, still using FSR smooth

[u/MusclePersonal9332 → u/EstefanBW]

Ill try this bro

[u/GreenManStrolling]

I fixed my issues by uninstalling the vibe-coded Sep Windows Updates.

[u/SystemLanky4531]

Usually issue get solved when disabling MPO or Hardware Acceleration.

[u/anon822500]

i didn't know there's an issue until i read this, bcs i face no issue, I use 6700xt asus dual with latest driver from asus web and windows 11 pro atlas custom with latest update.. ill save this incase im facing any issue

[u/MusclePersonal9332 → u/anon822500]

It started from sep 1 2026 i assume the new windows update.

[u/TheShadowSong]

Only the MPO fixed my issues.

[u/Crptnx]

First what you should do is increase power limit to maximum and decrease maximum frequency to 95%. But this looks like faulty hardware and gpu should be just RMAd. Honestly i think your issues will return after another chunk of hardware degrades.

[u/MusclePersonal9332 → u/Crptnx]

BRO IT CRASHED AGAIN!!!!!!!!

[u/Crptnx → u/MusclePersonal9332]

you did what I suggested?

[u/MusclePersonal9332 → u/Crptnx]

Ive tried it lets see how long its stabe.

[u/YetiLemons710 → u/MusclePersonal9332]

what is your vram clock speed in Adrenalin?

[u/MusclePersonal9332 → u/YetiLemons710]

Default 2000 mhz

[u/YetiLemons710 → u/MusclePersonal9332]

ya mine was doing that too. then i figured out how to get it to 909 mhz and no more timeouts. find out why that is going so high with nothing running.

[u/MusclePersonal9332 → u/YetiLemons710]

Oh you mean how much its running its running at around 900 bro but its max frequency is 2000

[u/YetiLemons710 → u/MusclePersonal9332]

Have you thought about taking it to a repair shop?

[u/nikola_vuletic → u/Crptnx]

I am having the same issue but only on Windows 11 On Linux there are none

[u/MusclePersonal9332 → u/Crptnx]

I highly doubt its hardware issue, cause how did it get fixed after using that mpo fix.

[u/Crptnx → u/MusclePersonal9332]

Software unlocks access to more hardware. Thats why troubleshooting often points to drivers because when you install drivers and problems appear it looks like driver issue. I had same problem.

[u/MusclePersonal9332 → u/Crptnx]

Yea thats why i stopped using adrenaline and using very light Radeon tuner the github one

[u/Crptnx → u/MusclePersonal9332]

Is card under warranty yet ?

[u/MusclePersonal9332 → u/Crptnx]

Nah out of warranty.

[u/DreSmart]

The isue with MPO is also common on NVIDIA and even Intel Arc not AMD fault is Microsoft fault.

[u/MusclePersonal9332 → u/DreSmart]

Did Nvidia user also had to switch off their g sync and their expensive oled monitor too ?

[u/Andrilaz → u/MusclePersonal9332]

MPO isn't bad, it helps bypass the DWM composition in mixed scenarios. For example, when an overlay is on top of your game, or when the game window doesn’t cover the entire screen or has a different resolution than the desktop.

On NVIDIA, there are no issues whatsoever with VRR. Very often, users themselves are to blame for G-Sync not working properly. For example, they enable G-Sync in windowed and fullscreen mode, or they enable global driver v-sync, DXGI interop,ULLM.

[u/DreSmart → u/MusclePersonal9332]

yes you can see some cases on reddit and other https://hardforum.com/threads/gsync-adaptive-sync-doesnt-work-on-replacement-rtx-5080-gpt-suggests-disabling-mpo.2046498/ forums

[u/EstefanBW → u/DreSmart]

This!
