Fix 2: Update your drivers

One of the most common causes of this problem is an outdated or a faulty device driver. So you should update your drivers to see if it fixes the problem. If you don’t have the time, patience or computer skills to update your drivers manually, you can, instead, do it automatically with Driver Easy

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing. Driver Easy handles it all.

You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a 30-day money back guarantee):

1)  Download and install Driver Easy.

2) Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.  

3) You can upgrade to the Pro version and click Update All to automatically download and install the correct version of ALL the drivers that are missing or out of date on your system.

You can also click Update to do it for free if you like, but it’s partly manual.

4) Restart your computer and hopefully the boot-up is smooth.


Fix 3: Run the SFC scan

System File Checker (SFC) is a handy feature in Windows that helps scan your system files and repair missing or corrupted system files(including those related to BSOD). To run the SFC scan:

1) On your keyboard, press the Windows logo key  and type cmd. Then right click on Command Prompt and click Run as administrator.



2) Click Yes when prompted to confirm.

3) In the command prompt window, type sfc /scannow and press Enter.



It’ll take some time for the SFC to replace the corrupted system files with new ones if it detects any, so please be patient.

4) Restart your computer and see if the fltmgr.sys BSOD problem has been sorted. If the issue still persists, please move on to Fix 4, below.


Fix 4: Check hardware issues

Faulty hardwares on our computer may not respond to the way our Windows system wants them to, hence this fltmgr.sys BSOD problem. To check hardware issues, you can remove/replace the devices and see if this solves the issue.

Fix 5: Check disks errors

Disk check is a useful in-built Windows tool that scans your hard disk and external drives for errors and fix them.


The disk error scanning takes only a few minutes. But once it detects any errors, the fixing procedure can take HOURS to complete. Make sure you have enough time set aside.

1) On your keyboard, press the Windows logo key  and E at the same time, then click This PC.

2) Right-click on Local Disk and click Properties.

3) Click the Tools tab > Check.

4) Click Scan drive.

5) Follow the on-screen instructions for Windows to detect and fix the errors found.

6) Restart your computer and see if it fixes the fltmgr.sys bsod problem. If not, repeat these steps on the other drives in your computer.
