Blue Screen: Fltmgr.sys Error Message—What to Do?

by Mike

If a blue screen appears in Windows with an fltmgr.sys error message, there can be several causes. These can be effectively resolved.

Fltmgr.sys Blue Screen: Causes and Solutions

If you encounter a blue screen with the message fltmgr.sys, there are several possible causes.

  1. Most commonly, this is due to a driver issue with individual devices, primarily hard drives. As a result, these devices no longer function optimally and can cause the system to crash.
  2. Updating the drivers via Device Manager is particularly important here. Use Device Manager to check which components are affected and update them.
  3. It can also help to perform driver updates in Safe Mode . To start Safe Mode after turning on the PC, press the [F8] key several times. Since the system boots with only the necessary drivers in this mode, you can determine whether one of them is causing the blue screen.
  4. It’s equally important to install Windows updates. If you haven’t downloaded any updates for months, that could be the cause of the problem.
  5. It’s not uncommon for the issue to be caused by malware that has found its way onto your computer. Use an antivirus scanner such as Malwarebytes Anti-Malware to scan your system for potential issues and remove them.
  6. The problem may be caused by the installed RAM. Open the Windows Memory Diagnostic Tool via the search box, check the RAM and follow the on-screen instructions to troubleshoot the issue.
  7. Note: A System Restore may be worth trying to reset the PC to a point when it was still functioning properly.

    Further Troubleshooting: Diagnostics and Tests

    1. You can resolve the issue by repairing the corrupted system files. Open the Command Prompt or Windows PowerShell by pressing [Windows key] and [X] and then clicking the option in the list.
    2. Enter the command sfc /scannow and press [Enter]. The tool will now search for corrupted system files and repair them automatically. 
    3. Next, enter the command DISM /Online /Cleanup-Image /RestoreHealth and confirm again. This will check and repair Windows images. Then restart your computer.
    4. It may also help to use the command chkdsk /f /r if the previous steps did not resolve the issue. This command checks your hard drives and places a heavy load on them to find and repair errors.
    5. Tip: If the steps above do not help, you should reinstall Windows. Be sure to back up your data first, as it will be lost during the reinstallation.
