Work with drivers

Update device drivers in Windows 10, as incompatible drivers often cause Blue Screen of Death.

This can be done manually by going to the hardware manufacturer's website. However, this will most likely take you a lot of time, since each driver will have to be updated separately. You can use a simpler method - download a third-party device that will all system components updated at all times.

Update your app

Since the FILE SYSTEM error (-805305975) is often caused by the Photos application, you can simply try updating this application.

Alternatively, you can update Windows completely, if any update is waiting to be installed, it doesn't hurt.


Run an SFC scan and then try running a deeper DISM scan.

- So, open the Windows search bar and type cmd, and open a command prompt as administrator.

- Next, enter the following line and press Enter: sfc / scannow.

  • DISM/Online/Cleanup-Image/RestoreHealth/source:WIM:P:SourcesInstall.wim:1/LimitAccess

Note: P is the letter of the connected drive with the Windows 10 installation.

After completing the DISM procedure, be sure to restart your computer.

Turn off protection

Disable any protection of your computer temporarily, as some applications (for example, Computer Associates EZ eTrust Antivirus) may cause a FILE SYSTEM error to appear.

Therefore, it is highly recommended to disable or uninstall the installed antivirus and firewall software.

  • chkdsk / f / r C:
  • Run this command for all partitions on your hard drive, so replace C with the appropriate drive letter as needed.
  • Restarting the computer will be a prerequisite for the new changes in the system to take effect.

Reset OS
