Desktop Window Manager Crashing

Question

So my desktop window manager has started to crash recently, since 28/09/22, which causes the whole display to freeze.

There appears to be no pattern that I can see in regards to what causes these crashes - will happen if PC is at load or is not at load.

The display will freeze, but from the sounds of it I can still interact with what was on the screen before - I can still communicate over discord, pause and play videos (obviously without the picture moving).

From reliability monitor, its definitely the desktop manager, and when I had TPM enabled on my motherboard the majoirty of the time after having to manually turn off the PC I would just get a black screen - would not see the motherboard manufacture BIOS options come up on start up - this has been resolved by turning off TPM on the board, but unsure if connected.

Technical details from the crash from reliability monitor:

I have ensured that all drivers are up to date, windows is up to date (Version 10.0.19044 Build 19044)

Is there going to be anything I can do to resolve this short of reinstalling windows in the entirety?

Answer 1

Here is a "summary" of the error:

dwmcore!MilFailFastForHR+69

There are some similarities to the error in the following link;

https://learn.microsoft.com/en-us/answers/questions/237700/dwm-crashing-randomly-causing-black-screen.html

In that link it was suggested that the weight of modern GPUs can be problematic and that re-seating the GPU may help.

Something you could consider.

Answer 2

Hi,

Issue appears to be resolved, thanks a lot!

Re-seating the GPU resolved it by the looks of it

Answer 3

OK, Good luck!

Answer 4

GPU re-seated, I shall let you know if this resolves the issues!
