  • Option 2 – Manually
    System File Checker is a built-in tool to check for corrupt, damaged system files and manage to restore them if there are any. However, this tool can only diagnose major system files, and won’t deal with damaged DLL, Windows Registry key, etc.

Option 1 – Automatically (Recommended)

  2. Open Fortect and click Yes to run a free scan of your PC.
  3. Fortect will scan your computer thoroughly. This may take a few minutes.
  4. Once done, you’ll see a detailed report of all the issues on your PC. To fix them automatically, click Start Repair. This requires you to purchase the full version. But don’t worry. If Fortect doesn’t solve the issue, you can request a refund within 60 days.

Option 2 – Manually

1) On your keyboard, press the Windows logo key and the R key at the same time to invoke the Run box.

2) Type cmd and press Shift+Ctrl+Enter together on your keyboard to open Command Prompt in the administrator mode.

Note: Do NOT click OK or just press the Enter key as that won’t allow you to open Command Prompt in the administrator mode.

3) Type sfc /scannow (or copy-paste) and press Enter. Then wait for the verification is 100% complete.

4) Restart your computer to check the blue screen issue is fixed or not.

If the result indicates there are broken files but SFC can’t fix them, you can turn to Deployment Image Servicing and Management (DISM) Tool for deeper examination and repair.
