BSOD starting after a random amount of time

x BlueRobot · Nov 10, 2021

No problem and hopefully you won't have any issues!

Roolek · Nov 10, 2021

Was fine for 3 hours last night and then about another 3 today, but still the same fault

x BlueRobot · Nov 11, 2021

The system appears to be more stable than before at least. Does the system only crash when playing WoW?

It may be worthwhile, amending the Driver Verifier settings to include only force IRQL checking and NDIS verification. You'll need to reboot for the changes to take effect.

Roolek · Nov 11, 2021

It does seem that its mostly when playing WoW yeah

I'll change driver verified now

x BlueRobot · Nov 12, 2021

Let's see if it DV is able to find anything with the other setting.

Do you have all of the latest Windows Updates and the latest WoW game client?

Roolek · Nov 12, 2021

Verifier didnt seem to find anything, booted that same way

Windows is updated and WoW is the latest client from the launcher its downloaded from

Roolek · Nov 12, 2021

No issues until playing WoW again, very odd

x BlueRobot · Nov 13, 2021

It would seem most likely that the WoW client is passing in a buffer to kernel-mode which is paged out, the IRQL is raised to 2 which means that the page fault which occurs, when afd.sys attempts to access the said buffer, it can't be resolved and therefore the system crashes with Stop 0xD1.

The call stack is the exact same each time and the address is always paged out:

Have you checked the WoW forum(s) for anyone who has been experiencing similar issues?

Roolek · Nov 13, 2021

I've made a post there and contacted their support through their ticket system, I haven't had great success in the past on those forums with anymore than just keep reinstalling tbh, but we'll see

x BlueRobot · Nov 13, 2021

Hopefully you'll get a decent response from someone, you can refer them to this thread too.

Roolek · Nov 16, 2021

Been pretty busy so haven't had time to try any more things, but their reply was not great as I've attached what was said, so no further developments yet

x BlueRobot · Nov 16, 2021

Do you they have any second-line support? I'm not sure why they're referring you to Microsoft since the issue is with their game client.

Have you tried clean installing the game client?

Roolek · Nov 16, 2021

They are sort of known for their support having gone downhill over recent years unfortunately

I have, but I'll do it again, because at this point, why not

Roolek · Nov 16, 2021

Crashed moments after starting the game on the fresh install funnily enough, anything different?

x BlueRobot · Nov 17, 2021

Unfortunately, it's the exact same problem as before. The only other suggestion I could give is to make sure you have the latest Windows Updates and possibly see if you can use an older version of the game client?
