2) Press the power button to turn on your PC and immediately when Windows is loading, long press the power button to turn it off.

3) Repeat 1) and 2) until the screen says Preparing Automatic Repair.

4) Wait for Windows to finish diagnosing your PC, and click Advanced options.


5) Click Troubleshoot.

6) Click Advanced options.

7) Click Startup settings.

8) Click Restart.

9) On your keyboard, press to enable Safe Mode with Networking.

10) Now you’ve successfully booted up in Safe Mode with Networking, continue with Step 2 to troubleshoot the blue screen problem.

3) Press the arrow keys to navigate to Safe Mode with Networking and press Enter.

4) Now you’ve successfully booted up in Safe Mode with Networking, continue with Step 2 to troubleshoot the blue screen problem.

Step 2: Update ALL the drivers available

Corrupted/outdated/missing drivers might very well be the reason responsible for our blue screen of death (BSOD) problem(fltmgr.sys). It can be difficult to put finger on which one is offending our system so we need to update ALL the drivers available to help resolve the situation.

There’re two ways you can update your device drivers — manually or automatically:

Update your drivers manually – To troubleshoot the issue, you can update all available drivers manually ONE BY ONE until you pin down the exact driver at fault. Firstly you’ll have to go to the manufacturer’s website, search for the most recent correct driver for the devices. Be sure to choose only drivers that are compatible with your variant of Windows system versions. Then download & update them all by yourself.


Update your drivers automatically  – Manually updating all the drivers is no picnic. If you don’t have the time, patience or computer skills to update your drivers manually, you can, instead, do it automatically with Driver EasyYou 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.

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.

Step 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.

Click Yes when prompted to confirm.

2) 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. ?

3) Restart your computer and see if the BSOD problem has been sorted.

Step 4: Check hardwares for physical 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 hardwares for physical issues, you can try to remove/replace the devices and see if this solves the issue.

Step 5: Check disks errors

Disk check is a useful in-built Windows tool that scans our 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.

To do so:

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 blue-screen-of-death problem. If not, repeat these steps on the other drives in your computer.


That’s it – 4 easy steps to help fix your fltmgr.sys blue screen error. Hope everything goes off without a hitch on your computer and feel free to comment below if you have any further questions or ideas to share with us. ?
