To troubleshoot the SYSTEM_SERVICE_EXCEPTION BSOD related to win32kfull.sys, you can try the following advanced steps:

1. Run Windows Memory Diagnostic Tool:

Since memory issues can cause this error, type "Windows Memory Diagnostic" in the Start menu, run the tool, and restart your PC to check for RAM errors.

2. Use Driver Verifier:

Run the built-in Windows Driver Verifier tool to identify problematic drivers. Open Command Prompt as administrator, type verifier, and follow the instructions to select all drivers. Restart your computer and check if any driver failures are logged.

3. Check for Corrupted System Files:

Run sfc /scannow in Command Prompt as an administrator to scan and repair any corrupted system files that may be causing the error. Also, use DISM /Online /Cleanup-Image /RestoreHealth for additional repairs.

4. Update or Roll Back Drivers:

Even if you've updated drivers, try rolling back graphics or other critical drivers to previous versions. Use Device Manager to manage this.

5. Analyze Dump Files:

Use tools like BlueScreenView or WinDbg to analyze memory dump files located in C:\Windows\Minidump. These tools can help pinpoint which file or driver is causing the BSOD.

6. Check Event Viewer:

Go to Event Viewer > Windows Logs > System to find specific error messages around the time of the BSOD, which may provide clues.

These steps should help identify the cause of the error. Let me know if you need more detailed guidance on any of these steps!
