This is similar behavior to what I see in the games, sometimes it crashes quickly, sometimes after half an hour. So, I downloaded OCCT and ran a stress test on the PSU with it - the first time it crashed after two minutes (same behavior as in the games) and the second time it ran for 20 minutes, after which I had to turn it off for other reasons. What would you suggest that I do here? As it is now, gaming is impossible on a brand new, high-spec, desktop computer :( GPU: Nvidia GeForce RTX 3080 Ti (current driver: 527.37) Is there any way to install/update those drivers without actually having a controller? There seems to be a lot of people having similar problems, in many cases it seems to have been resolved by updating the drivers for XBox controller - however since I do not have a controller I am not sure if this is applicable. Trying both Full screen and Windowed Full screen in the games

Stopping all unnecessary services (e.g. Reducing the frame rate in the games (this lowers GPU temp to about 68, but the DWM crash still occurs just as frequently). Updating the graphic card driver to the latest one, as well as reverting to older ones that have worked previously before this problem started occurring. Updating Windows 11 to the latest version (22 H2), with all the available KB's. The GPU power consumption is around 240 watts (and as mentioned, it is not a GPU shutdown - the GPU keeps running). However, this is not happening due to GPU overloading, the temperature is consistent at 70-72 degrees. Fortnite and Modern Warfare II - not in for example Rocket League. It seems to only happen in GPU intensive games, e.g. Usually, the DWM exit seems to happen on its own. Occasionally there might be another error just before it, for example 'Faulting application name: XboxGameBarSpotify.exe, version: 0.0.0.0, time stamp: 0圆3517b83'. (Process exit code: 0x0000042b, Restart count: 1, Primary display device ID: NVIDIA GeForce RTX 3080 Ti)' The only consistent event in the event log when this happens is this: 'The Desktop Window Manager process has exited. The graphic card is still running, the lights on it are turned on. Suddenly during the game (can be after 1 minute or 30 minutes, but usually not longer than that) the screen goes black ('monitor cannot find any input') and the audio disappears. Since about two weeks back, I have frequent crashes playing various games, e.g.
