Solution Steps
- 1 Boot into Safe Mode: Use Shift + Restart to access Safe Mode. This will prevent the problematic driver from loading, allowing you to fix it.
- 2 Run Driver Verifier: Type 'verifier' in the Start menu and run as administrator. Select 'Create standard settings' and 'Automatically select all drivers installed on this computer'. Restart. Driver Verifier will stress-test drivers and identify the faulty one. If it causes a boot loop, boot into Safe Mode and run 'verifier /reset'.
- 3 Update or roll back drivers: In Device Manager, expand categories and right-click each device to update or roll back drivers. Focus on devices that were recently changed.
- 4 Run SFC and DISM: Open Command Prompt as administrator and run 'sfc /scannow' and 'DISM /Online /Cleanup-Image /RestoreHealth' to repair system files.
- 5 Check for Windows updates: Go to Settings → Windows Update and install all updates, as they may include driver fixes.
- 6 If the error persists, check the minidump files: Use WinDbg to analyze C:\Windows\Minidump to identify the exact driver causing the issue.
