What Is Ntfs.sys

Ntfs.sys is located in C:\Windows\System32\drivers folder. Ntfs.sys indicates either the system file that is essential in running Windows or the hardware driver that allows the Windows operating system to read and write to NTFS drives. Thus, if you get a BSOD with the stop code: NTFS_File_SYSTEM (Ntfs.sys), that means there is something wrong with the hardware driver. If you receive the error code: SYSTEM_SERVICE_EXCEPTION (Ntfs.sys), you probably get a corrupted system file.

What Failed NTFS.sys

Every error has its causes. The culprit for NTFS_File_SYSTEM (Ntfs.sys) is likely to be disk corruption, be it NTFS file system corruption or disk errors like bad sectors. Besides, corrupted hard drive drivers can also result in a failed Ntfs.sys. And the SYSTEM_SERVICE_EXCEPTION (Ntfs.sys) may be induced by antivirus software that is conflicted with the system, corrupted or outdated driver, or problematic RAM sticks.

How to Fix BSOD Caused by Ntfs.sys Failure

Specify the error message on your computer screen and carry out the corresponding fixes to remove the Ntfs.sys error.

Error Code 1. NTFS_File_SYSTEM (Ntfs.sys)

As mentioned, the main culprit for a failed Ntfs.sys in such a situation is a file system error, bad sectors, or outdated device drivers. Given that, the solutions to this issue are quite clear: fix disk corruptions and update the device driver.

Since there are multiple disks and drivers on a computer, you first need to specify the drive(or device) or driver that is causing the problem using the Event Viewer.  To check it, you need to enter Safe Mode.

Step 1. Hold down the power button for 10s to shut down the computer.

Step 2. Press the power button to start the computer. Once you see the first sign of Windows has started, e.g., the logo of the manufacturer, hold down the power button for 10s again to turn off the device.

Step 3. Press the power button to start the computer. Once Windows restarts, hold down the power button for 10s to turn off the computer.

Step 4. Press the power button to start the computer, and don't interrupt it this time. Then you will see your computer in WinRE.

Step 5. On the "Choose an option" screen, choose "Troubleshoot" > "Advanced options" > "Startup Settings" > "Restart".

Step 6. After the restart, you will see a list of options, as shown in the image below. Select "5" or press "F5" to enable Safe Mode with Networking.

Enter Safe Mode

Now you need to check Event Viewer:

Step 1. Click "Start" and enter the event viewer.

Step 2. Right-click "Event Viewer" and choose "Run as administrator".

Step 3. Expand "Windows Logs" and choose "System".

Step 4. Check the errors that coincided with the blue screen and fix the error according to the information.

Check Event Viewer

Method 1. Fix Disk Corruptions

The Windows built-in Chkdsk utility can fix disk errors like file system errors and bad sectors. Thus, you can solve the disk corruption with the command-line tool. If you don't want to use command lines, applying the disk checking feature has the same effect.

Step 1. Enter "Safe Mode with Command Prompt" using the way introduced above.

Step 2. Open "This PC", right-click the problematic drive and choose "Properties".

Step 3. Go to the "Tools" tab, click "Check".

Check disk corruptions

Method 2. Update Device Driver

An outdated or corrupted driver is the cause of the failed Ntfs.sys in most of the cases. If you figure out what the faulty driver via Event Viewer, go to Safe Mode with Networking to update the corresponding driver.

Step 1. Right-click on "This PC" and go to "Manage" > "Device Manager".

Step 2. Expand "Display adapters", right-click on the graphics card driver and choose "Update driver".

Update driver

According to Microsoft, there are other tips worth trying to fix the blue screen of death caused by the Ntfs.sys error.

  • Disable any virus scanners, backup programs, or disk defragment tools.
  • Run hardware diagnostics provided by the manufacturer.
  • Ensure there is enough space on the system drive. If not, you can extend the system drive to make Windows run properly.


Based on the possible reasons that lead to the Ntfs.sys error, in addition to updating the driver using the way introduced above, here are other solutions you can apply.

Method 1. Update Windows

Updating Windows can not only fix some known bugs or problems but also update necessary drivers.

Step 1. Enter safe mode following the steps provided.

Step 2. Click "Start" and type update.

Step 3. Choose "Check for updates".

Step 4. Windows will show you the new updates available. Click "Install now" to update your Windows. (Make sure you install all the updates available.)

Update Windows

Method 2. Run System File Checker Tools

System File Checker tool is a built-in utility in Windows that can check and repair missing or corrupted system files. It will repair the failed Ntfs.sys file automatically. Follow the steps introduced in the last part to enter Safe Mode with Command Prompt and then:

Step 1. In safe mode, click "Start" and type cmd.

Step 2. Right-click "Command Prompt" and choose "Run as administrator".

Step 3. If you are using Windows 10, you should first run DISM.exe: DISM.exe /Online /Cleanup-image /Restorehealth to make a Windows image to protect your data:

Step 4. When the DISM command has completed, type the following command: sfc /scannow to start scanning and repairing your system files.

Method 3. Check the RAM

Faulty RAM stick installation or incorrect RAM setup may also induce an Ntfs.sys error. First, you need to check the hardware. To do so, turn off your computer and reconnect the RAM sticks. You can troubleshoot the problematic RAM stick by removing all of them and trying to power on each stick one by one.

If there is nothing wrong with the hardware, you need to check the timings and frequencies of the RAM. You can get the recommended values from the manufacturer and apply third-party tools to check the actual values of the RAM sticks. If they don't match, you can enter BIOS to adjust the RAM values to the recommended ones.

Tips and Notifications

  • You can also apply the driver installation disc to update the corresponding hardware driver.
  • Both updating driver and running System File Checker tool can be applied to both of the situations.
  • Disable antivirus or similar software is only helpful in Windows 10.
