Fltmgr.sys Blue Screen of Death

This blue screen is caused due to faulty hardware or corrupt device drivers present on your device. FltMgr.sys is a “system” file used by Windows to help control various aspects of your hard drives & files. It is known as Microsoft Filesystem Filter Manager and its main responsibility is to make certain that the data written to the hard drive is correct and not corrupted.

If this file is missing or corrupt, the Blue Screen of Death will most likely appear. In other instances, Windows will not load completely.

How to Fix Fltmgr.sys Blue Screen of Death Error

Restart Your PC

It may seem a simple step, but it can be the case that the File System Manager was not loaded properly when the system booted up. In any case, if you have any doubts, you should just restart your PC. This will clear the system’s RAM and provide another chance for it to boot up cleanly.

Check Newly Added Hardware

This error is most likely caused if you either have incorrect drivers or have faulty hardware installed on your computer. The faulty hardware may not respond or act according to how the operating system wants it to. This may cause the blue screen if the module stops responding or acts in a dangerous way.

If you have added any new hardware to your PC, remove it and try replacing it with the older/different one.
