Windows 10: Windows desktop manager crashing

So ive had this issue for a week now, ever since i built a new pc and upgraded to windows 11 ive gotten crashes when im playing a game. Black screen for a second and app crash. I have a rtx 4090. Ive tested the psu and gpu by switching to another unit and still it crashes. Ive done a clean windows install and the problem still persists. I dont have gamebar now but ive tried updating it and still didnt work. The only hardware problem i can think is the problem is the motherboard. I have no clue what to do at this point...SourceDesktop Window ManagerSummaryStopped workingDate‎2025

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?

 

all games crash!

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.

 

Desktop Windows Manager Crash

Hi MrSerp,

Welcome to Microsoft Community.

I'm Hahn and I'm here to help you with your concern.

It seems like you're experiencing crashes with the Desktop Window Manager (dwm.exe) on your Windows 11 system. Here are a few steps you could try to troubleshoot and resolve the issue:

1. Update Graphics Drivers: Although you've fixed the GPU issue earlier, ensure you have the latest drivers installed for your GPU. Sometimes, conflicts or outdated drivers can cause issues with the Desktop Window Manager.



2. Run System File Checker (SFC): Open Command Prompt as an administrator and run the command `sfc /scannow`. This tool scans and repairs corrupted system files that might be causing the Desktop Window Manager to crash. Use the System File Checker tool to repair missing or corrupted system files - Microsoft Support

3. Check for Valorant-Related Issues: While it might seem unlikely, certain games or applications can conflict with system processes. Ensure that Valorant is updated to the latest version. You might also try temporarily uninstalling it to check if the issue persists without the game installed.

I recommend trying a clean boot which starts Windows with a minimal set of drivers and startup programs. It can be used to determine whether a background service or program is interfering or causing a problem. How to perform a clean boot in Windows - Microsoft Support



These steps of "clean boot" might look complicated at first glance. However, to avoid any trouble for you, please follow them in order and step-by-step.

5. Windows Memory Diagnostic:

Run the Windows Memory Diagnostic tool to check for memory-related issues. Press `Win + R`, type `mdsched.exe`, and press Enter. Follow the on-screen instructions to restart your computer and check for memory problems.

6. Check for System Errors: Look into Event Viewer for any additional error logs related to the Desktop Window Manager crash. It might provide more specific details about the issue.

I hope this helps. If there is anything not clear, please do not hesitate to let me know.



Your Sincerely
