  1. Press the Windows + X keys on your keyboard, and then choose Device Manager from the context menu.

  7. A driver update is only a possible hotfix for the blue screen issue at hand. If this method doesn’t work for you, proceed to the next solution!

Method 4. Run the System File Checker and CHKDSK Command

The System File Checker (SFC) is a troubleshooting tool available in Windows 10 by default. It’s able to automatically detect corrupted system files, and repair them to working order. You can use the SFC scan to potentially fix any problems with blue screen errors.

If the SFC scan didn’t work, continue with the steps and try running Check Disk to repair your PC. The chkdsk command attempts to identify and get rid of disk issues, which may help you with resolving issues with fltmgr.sys.

  1. Open the search bar in your taskbar by clicking on the magnifying glass icon. You can also bring it up with the Windows + S keyboard shortcut.
  2. Type Command Prompt in the search box. When you see it in the results, right-click on it and choose Run as Administrator.
    command promt
  3. When prompted by the User Account Control (UAC), click Yes to allow the app to launch with administrative permissions.
  4. Once the Command Prompt window is open, type in the following command and press Enter to execute it: sfc /scannow
    command prompt: sfc/ scannow
  5. Wait for the System File Checker to finish scanning your computer. If it finds any errors, you'll be able to fix them automatically through the SFC command itself, which may also fix related errors.
  6. Next, input the following command and press Enter to execute it: chkdsk C: /f /r /x
    command prompt: check disk
  7. This command is going to check the C: drive. If your Windows 10 has been installed on a different drive, make sure to modify the command accordingly by replacing “C:”.
  8. Wait for the Check Disk command to finish running. It’ll attempt to fix issues with the drive and recover any readable information. Restart your device once both commands have been executed.
