However, the built-in Blue Screen troubleshooter has been removed in Windows 10 v1809 and later versions. In such situations, you will need to take different steps to troubleshoot the issue.

For a lower version than Windows 10 v1809, you can do the following steps:

  1. Open the Settings window.
  2. Navigate to Update & Security > Troubleshoot > Blue Screen, and then click Run the troubleshooter.

For a higher version than Windows 10 v1809, you can do as follows:

  1. Open the Search window and type “get help“.
  2. Select the Get Help app from the search results.
  3. When the Get Help app opens up, type a related keyword, like Troubleshoot BSOD error, Troubleshoot Blue Screen error, Fix Blue Screen errors, etc.
  4. Press Enter to open the Blue Screen Troubleshooting wizard.
  5. Follow the instructions displayed in the app to troubleshoot the error.

# 4. Update/Roll Back/Disable/Reinstall Driver

Step 1. Press the Win + R keys to open the Run window, type “mdsched.exe” and press Enter.

Step 2. In the Windows Memory Diagnostic window, click Restart now and check for problems (recommended).
