The Blue Screen Online Troubleshooter from Microsoft more often than not will fix BSOD errors.

2] Run SFC and DISM scan

The System File Checker is a command-line utility that checks all of the system files for problems. If a corrupt system file is triggering this error, the SFC scan will most likely fix it. Otherwise, you will have to follow up with the DISM (Deployment Image Servicing and Management) scan which is similar but slightly different in function and will fix corrupt or damaged system images on your Windows 11/10 computer.

3] Restore or Replace the smss.exe file

Restore or Replace smss.exe file

The smss.exe is the executable file responsible for running the Session Manager Subsystem (or Windows Session Manager). It’s an important component of the Windows operating system that starts running immediately when you click the power button. It’s responsible for creating user sessions and monitoring other crucial system processes to make sure they’re working correctly. The legitimate smss.exe file is located in the C:WindowsSystem32 directory.

This process will crash your computer if csrss.exe (Client Server Runtime) or winlogon.exe (Windows Logon Application) malfunction or unexpectedly stop working, hence the BSOD error in view. Also, if the smss.exe file gets damaged, corrupted, or missing your system may freeze or stop responding.

This solution requires you to restore or replace the smss.exe file on your PC with a healthy copy from Winbindex by simply downloading the file and copying it to the system32 folder. To restore or replace the file locally, do the following:

  • Enter the Advanced Startup Options screen.
  • Access Command Prompt.
  • In CMD prompt window, enter the following lines and hit Enter after each line:
cd windows/system32/ 
copy c:windowssystem32dllcachesmss.exe
  • Alternatively, instead of the last line, you can use:
copy c:windowsServicePackFilesi386smss.exe
  • Once done, type exit and hit Enter to close Command Prompt and restart your computer.

A problem with your hard disk typically causes BSODs. So, you can run the CHKDSK command to see if this is the case. This command will examine your hard disk for problems and fix them (if possible).

To run CHKDSK, do the following:

  • Press Windows key + R to invoke the Run dialog.
  • In the Run dialog box, type cmd and then press CTRL + SHIFT + ENTER to open Command Prompt in admin/elevated mode.
  • In the command prompt window, type the command below and hit Enter.
chkdsk /x /f /r

You will receive the following message:

CHKDSK cannot run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts? (Y/N).

  • Press the Y key on the keyboard and then reboot your computer.

After CHKDSK completes, check to see if the issue is resolved. Otherwise, try the next solution.
