Fix 1: Run SFC (System File Checker)

Running the System File Checker (SFC) is a fundamental step in addressing the ntoskrnl.exe BSOD error, as it helps identify and repair corrupted system files that may be causing the problem.

  • Step 1: Open Command Prompt as Administrator:
    • To begin, press ‘Windows + X’ on your keyboard.
    • From the menu that appears, select ‘Windows Terminal (Admin)’ or ‘Command Prompt (Admin)’.
  • Step 2: Run the SFC Scan:
    • In the Command Prompt window, type the following command: sfc /scannow.
    • Press ‘Enter’ to execute the command.
  • Step 3: Wait for the Scan to Complete: The SFC scan will now begin. It may take some time to complete, so please be patient and avoid interrupting the process.
  • Step 4: Review the Scan Results: Once the scan is finished, you’ll receive one of the following messages:
    • Windows Resource Protection did not find any integrity violations: This means no corrupted files were found.
    • Windows Resource Protection found corrupt files and successfully repaired them: This indicates that corrupted files were discovered and successfully repaired.
    • Windows Resource Protection found corrupt files but was unable to fix some of them: In this case, the SFC scan identified corrupted files but couldn’t repair them all.
  • Step 5: If Corrupted Files Were Found: If corrupted files were found and successfully repaired, you can proceed to check if the ntoskrnl.exe BSOD error is resolved. Restart your computer and observe its performance.
  • Step 6: If SFC Couldn’t Fix All Corrupted Files: If the scan couldn’t fix all the corrupted files, you may need to perform additional steps to address the issue:
    • Run the SFC scan again to see if it can repair the remaining files.
    • If the issue persists, consider using the DISM (Deployment Image Service and Management Tool) utility to repair the Windows image. To do this, follow these steps:
    • In the same Command Prompt window, type: DISM /Online /Cleanup-Image /RestoreHealth and press ‘Enter’.
    • Wait for the DISM tool to complete its process, which may also take some time.

After completing both SFC and DISM scans, restart your computer and check if the ntoskrnl.exe BSOD error is resolved.

Running the SFC scan and, if necessary, the DISM scan can often help eliminate ntoskrnl.exe BSOD errors caused by corrupted system files. However, if the issue persists, you may need to explore other solutions, as outlined in the subsequent fixes.

Fix 2: Update or Roll Back Drivers

Outdated or incompatible drivers can lead to conflicts with the ntoskrnl.exe file, resulting in the BSOD error. In this fix, we’ll guide you through the process of updating or rolling back your drivers to resolve the issue.
