Solution Steps
- 1 Boot into Safe Mode: Restart and press F8 (or Shift + F8) before Windows loads. If that fails, use WinRE. Safe Mode loads minimal drivers, so if the BSOD doesn't occur, it's driver-related.
- 2 Uninstall recently installed software: Go to Settings → Apps → Installed apps. Sort by installation date and uninstall any recently installed drivers or software, especially those from unknown publishers.
- 3 Update drivers: Open Device Manager (Windows key + X → Device Manager). Right-click each device and select 'Update driver'. Pay special attention to network and storage controllers.
- 4 Run System File Checker: Open Command Prompt as admin and type 'sfc /scannow'.
- 5 Use Driver Verifier: Open Command Prompt as admin, type 'verifier' and create custom settings to identify the faulty driver. The BSOD will name the driver.
- 6 Check for Windows updates: Settings → Windows Update → Check for updates.
