Hello everyone,
I experienced an critical and sensible Bug on my Desktop-PC:
since installing Windows 11 25H2 (Build 26200).
In short:
Random complete system freezes
After about 1-2 minutes, a black screen appears on all displays
No blue screen
If the black screen persists for too long, I have to reinstall all graphics drivers using DDU. Restarting during a freeze is only possible via a hard shutdown followed by a cold boot.
After restarting: GPU shows error code 31 in Device Manager
GPU only works again after reinstalling the AMD chipset driver
Error codes:
LiveKernelEvent 141 (WATCHDOG)
LiveKernelEvent a2000002
LiveKernelEvent a1000001
LiveKernelEvent 191

Are there any known investigations or fixes from Microsoft or AMD?
Best regards, Lasse
