Hi Kevin Lapointe,
Welcome to Microsoft Community. I'm Mosken, let me help you.
According to your description, I knew that your Windows 11 crashes randomly, even if you have reinstalled the system. Is that right?
First, please check if there are .dmp files in the C:\Windows\Minidump directory.
- If so, package these files, upload them to OneDrive, and share them, and then include a link to share them in the next reply. Since these files detail exactly what happened when your system crashed, this helps us help you resolve the issue.
- If not, run the following command to try to enable it. Win logo key + Q*, open the search box, type "cmd", then right-click* Command Prompt*, select Run as administrator), and then type the following command.*
wmic recoveros set DebugInfoType=3
This is to enable blue screen logging. You need to try to access the C:\Windows\Minidump directory to see if there are .dmp files after the next blue screen appears.
Then according to the error information in the Dxdiag file you provided, it is mainly related to some applications named wallpaper64.exe, Aac3572MbHal_x86.exe. You may try disabling/uninstalling these software (including unmentioned third-party protection software, anti-virus software) and see if the system is normal.
Then you can try the general troubleshooting below.
1. Update all computer hardware drivers
You may try to reinstall all drivers, especially the graphics card driver. You can go to the official website of your device manufacturer to download the corresponding model driver, and then install it manually. After the driver installation is complete, it is recommended that you check if the device works properly, and then restart to check again.
2. Repair possible corrupted system files
You may try the following commands to fix possible corrupted system files. Please run Command Prompt as an administrator ("Win" logo key + "Q", enter "cmd", select "Run as administrator"), and enter the following commands one by one. These commands require network support, please keep your network stable and smooth.
sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth
3. Clean the update cache
Please run Command Prompt as an administrator ("Win" logo key + "Q", enter "cmd", select "Run as administrator"), and enter the following commands one by one.
net stop wuauserv
net stop bits
net stop cryptsvc
rd /s /q c:\Windows\SoftwareDistribution
rd /s /q %temp%
rd /s /q c:\Windows\temp
net start wuauserv
sc config wuauserv start=auto
net start bits
sc config bits start=auto
net start cryptsvc
sc config cryptsvc start=auto
4. Check for system updates.
You can follow the directions below to check system update, as most issues can be resolved with an update. On the desktop click "Start" > "Settings" > "Update & Security" > "Windows Update" > "Check for updates".
The above steps are provided based on the information I have learned so far, and hope that could help you a little. If the problem still exists, please provide us a full PSR from the beginning, through the whole process, and until the error message is displayed, so we can further investigate.
