How to fix stop code fltmgr.sys Windows 11

1. Check for hardware problems

Before proceeding with this method, you should restart your PC . There have been cases where the error occurred because the file fItmr.sys was not initialized correctly. If the problem also occurs after booting, proceed with the steps below.

The first thing you should do is check your computer for any faulty hardware that might be causing the problem. If the error started occurring after you moved old hardware components to new ones, that could be causing the problem.

You can try switching back to the old hardware or try the new hardware on a different device.

Another thing you can do is run a CHKDSK scan , which can analyze the hard drive for errors and fix those identified. Follow these steps to do that:

2. Fix device driver

If the problem is not with the hardware, then the next thing you should check is the device driver. Unfortunately, this error code doesn’t specify which driver might be the problem, so you need to update all important drivers.

You can do this manually using Device Manager , or you can use a third-party utility that can scan your system for outdated or corrupted drivers and then update/install reset them.

If you choose to do it manually, you can see instructions on how to update drivers in Windows . If the problem started happening after you updated/installed the driver, you can downgrade or uninstall the problematic driver and see if that helps.

However, if you want to delegate this work to a third-party tool, here are some options to consider:

  • DriverFix – This tool will scan the system for outdated/corrupt drivers and recommend updates that are officially released by the manufacturer. All you need to do is give the tool access to the necessary files and it will automatically install the driver for you.
  • Driver Easy – It is another simple tool that will identify drivers that need to be updated or reinstalled. There are two versions; free and paid.
  • Ashampoo Driver Updater – This program scans your hardware and drivers, then installs the latest updates of any outdated drivers that may be hidden in the system.

3. Undo recent changes

If the error started appearing after you made certain changes to the system, then you can try to undo those changes and check if that fixes the problem.

The first thing you should do is uninstall recent Windows updates. Microsoft updates can sometimes be buggy and cause new problems in the system instead of solving existing problems.

If uninstalling recent updates didn’t do the trick, then the next thing to do is to check if any new or old third-party apps are causing the problem. To do this, first launch Windows into Safe Mode .

This mode launches Windows with just a basic set of drivers and programs, making it easy to determine if background apps are the culprit.

After you are in Safe Mode, check to see if the problem reappears. If not, you can try to uninstall any recently installed apps as they are most likely the culprit.

If you are unsure about the applications, navigate to the Services tab in the System Configuration dialog box .

Now divide the services into two parts and enable all the services in the first section. Wait to see if the error reappears. Keep narrowing until you find the culprit.

4. Contact Microsoft Support

If the methods listed above do not fix the problem for you, then you can report the problem to the official Microsoft support team. Hopefully they will assist you in determining the exact cause of the problem and suggest you the appropriate fix. In addition, you can also use the Event Viewer utilityon Windows to check the BSOD log file to identify the culprit yourself.

Hopefully one of the methods listed above solved your problem. The article strongly recommends that you update your device drivers all the time to avoid such problems in the future. Regularly installing available system updates is also important, as they contain bug fixes and protect your system.
