Windows 10: BSOD + excessive app crashes on Windows 11

Hello! for the past few days I have to deal with a highly misbehaving Asus ROG Strix SCAR 16 G634JZR when trying to play the game Age of Wonders 4 on Windows 11. The game is crashing constantly 16 times within 3 days with competely differend played times varies from 4 mins played to 6h played and without any corresponding entries in the event viewer. I also had 2 BSOD within 4 days also when playing Age of Wonders 4, which has happened only once before about a month ago while playing World of Warcraft.I installed every "not beta" os / bios / driver update I could find and did run a

all games crash!

I suggest you run rthdribl > http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip
Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
What X1800XT model do you own exactly?

ive watch my temps and both the cpu and gpu are within normal ranges. when it freezes it simply freezes the image and stops the sound. i must reboot to get back to windows.

 

Windows 11 constantly crashes without BSOD

After updating Windows 10 to Windows 11, my PC keeps crashing without BSOD. It takes between 15 minutes to several hours after start-up to crash. When the crash occurs, the PC first freezes for a few seconds, after which it starts rebooting. These crashes have never occurred before the update.

Attached here is the minidump file produced by the latest crash:

My hardware:

• Motherboard - X570 Asrock Phantom Gaming 4 rev 1.05
  
• CPU - AMD Ryzen 7 5800x
  
• GPU - AMD Gigabyte RX 6700xt
  
• RAM - Teamgroup Vullcan Z 2x16 Gb
  

I have tried:

• Reinstalling the GPU driver
  
• Running SFC /Scannow
  
• Running DISM/Online/Cleanup-Image/RestoreHealth
  
• Resetting Windows with 'Keep my files' option
  

None of these have helped alleviate the crashes.
