Fortnite causes IRQL_Not_Less_Or_Equal BSOD error since update
Hi! I first went to Epic Games with this problem, they sent me to Microsoft, who've sent me here, so I hope someone will be able to help me.
I've been playing Fortnite on my HP Pavilion 15-n002sh notebook, running Windows 8.1, with Intel Core i5-4200U CPU, 8 GB RAM and AMD Radeon HD 8670M GPU. Everything worked fine for months, then after the previous update (v21.20) the game started causing an IRQL_Not_Less_Or_Equal stop code (Blue Screen of Death) whenever I join a game. Nothing else was changed on the PC, only Fortnite was updated, and it's only Fortnite that causes the crash.
Since then I tried fixing it by:
launching the game in different rendering modes (I play in performance mode but the problem persists in the other two as well)
verifying the game files
completely uninstalling the game and launcher then reinstalling it
running it as an administrator
adjusting the compatibility settings
updating the graphics card drivers
checking for windows updates
disabling the antivirus software (Avast)
checking for viruses
repairing visual C++ redistributables
running diagnostics and stress tests on the memory and the graphics card (they're both working fine)
performing a clean boot
None of the above worked. Since then I found some other players on reddit who're saying that they encountered the same issue after the update, similarly on Windows 8.1 with AMD GPUs.
I also generated a complete memory dump and this is what the analyzer said:
On Sun 2022.07.17. 14:50:01 your computer crashed or a problem was reported
(I'm a bit of a noob, so I have no idea how to make sense of this or how to proceed.)
I thought the problem would be on Fortnite's end, but their customer service insisted that it isn't and that I should contact Microsoft support. Microsoft support told me to come here. So here I am. I've been trying to fix this for almost two weeks now, so any help would be greatly appreciated!
