Steps to fix FAT file system Windows 10 error
Solution 1 – Update your Windows and drivers
The most common BSoD errors are caused by outdated or incompatible drivers, so in order to fix this issue we recommend that you download the latest drivers for your motherboard, chipset, graphics card and other devices that you have installed. You can download all the necessary files from the manufacturer's website.
In addition to downloading the latest drivers, it is also quite important to download and install Windows 10 updates. Microsoft is working hard to find and fix hardware and software conflicts, and in some cases, the FAT FILE SYSTEM can be fixed by performing a Windows 10 update.
Update drivers automatically
Searching for drivers on your own can be time consuming. Therefore, we recommend that you use a tool that does this automatically. Using an automatic driver updater will save you the trouble of manually searching for drivers, and will always keep your system updated with the latest drivers.
Tweakbit Driver Updater (approved by Microsoft and Norton Antivirus) will help you update drivers automatically and prevent damage to your PC caused by installing wrong driver versions. After several tests, our team concluded that this is the best automated solution.
Here is a quick guide on how to use it:
- Download and install TweakBit Driver Updater
- Once installed, the program will start scanning your PC for outdated drivers automatically. Driver Updater will check the versions of your drivers installed in its cloud database for the latest versions and recommend the appropriate updates. All you need to do is wait for the scan to complete.
- At the end of the scan, you will get a report on all the problem drivers found on your PC. Review the list and see if you want to update each controller individually or all at once. To update one controller at a time, click the "Update Controller" link next to the controller name. Or simply click the Update All button at the bottom to automatically install all recommended updates.
Note: Some drivers have to be installed in several steps, so you will have to press the "Update" button several times until all their components are installed.
Solution 2 – Run the BSOD troubleshooter
The next tool that we are going to use is Windows Built-in 10 troubleshooter. This tool can help you deal with all kinds of system issues including BSOD errors.

Solution 3 – Run the SFC scan
The next troubleshooting tool we are going to test is the SFC scan. This is a command line tool that serves as a system scanner, and is as effective as basically any other existing troubleshooting tool.
Here's how to run the SFC scan on Windows 10:
- Right-click on the Start menu button and open the command prompt (administrator).
- Enter the following line and press Enter: sfc / scannow
- Wait until the process ends (it may take a while).
- If the solution is found, it will be applied automatically.

Solution 4 – Run DISM
And finally, the last troubleshooting tool we are going to use is DISM. This tool displays the system image again, so it is very possible that it will eliminate possible BSOD errors. Including the FAT FILE SYSTEM error (hopefully).
We will guide you through the standard and procedure using the installation media below:
- Right-click Start and open Command Prompt (Administrator).

- Be sure to change a X value with the drive letter mounted with Windows 10 installation.
- After the procedure is complete, restart your computer.
Solution 5 – Try to start your computer with a single hard drive
As we already mentioned, FAT FILE SYSTEM is usually caused by your hard drive, and sometimes you can fix this problem by unplugging your second hard drive and starting Windows 10 without it. If you don't have two or more hard drives, you can skip this solution and try a different one.
To disconnect your hard drive, you will have to open the case of your computer and disconnect the power cable that connects to your hard drive. Be sure to do this for all hard drives except the one with Windows 10 installed on it.
In addition to internal hard drives, users suggest that you remove any additional memory cards and USB drives that may have been connected to your PC.
If the FAT FILE SYSTEM BSoD error is fixed after disconnecting additional hard drives, you can shutdown your computer and try to reconnect them one by one until you find the one causing the FAT FILE SYSTEM error.
Solution 6 – Check that your hardware is working properly
Blue screen of death errors can often be caused by faulty hardware, and if that's the case, you need to find the faulty hardware and replace it. If your hardware is new and recently installed, it may not be compatible with your PC.
In case you don't have any recently installed hardware, this means your current hardware is not working properly.
Few users reported that a faulty motherboard is causing this issue, so be sure to check it out. Keep in mind that almost any other hardware can cause this problem, and if you need help diagnosing faulty hardware, it is best to take your PC to the repair shop.
Solution 7 – Uninstall Folder Protect and Folder Lock software
Certain folder encryption and protection software may cause FAT_FILE_SYSTEM to appear. According to users, software like Folder Protect and Folder Lock may cause a BSoD error as its encryption method interferes with your hard drive.
If you use these tools, the only solution is to uninstall them from your computer.
Few users reported that they cannot even access Windows 10, so they cannot uninstall this software. If the FAT FILE SYSTEM error prevents you from accessing Windows 10, you can try to uninstall these tools from safe mode. To access Safe Mode, you must do the following:
- As your computer boots, restart it. You will have to repeat this step several times before your PC starts the automatic repair process.
- Choose Troubleshoot> Advanced Options> Startup Settings and click Restart. When your computer restarts, press F5 or 5 to access Safe mode with networking.
After accessing Safe Mode, you should be able to remove the problematic software without any problem.
Solution 8 – Uninstall your antivirus software
Due to incompatibility issues, some antivirus software may cause a FAT FILE SYSTEM error to appear. If you have this error in Windows 10, we recommend that you remove the currently installed antivirus software and check if that fixes the problem.
If the problem persists even after removing the antivirus software, you may need to use a special uninstaller to remove your antivirus software. Many antivirus companies offer tools that will completely uninstall your antivirus software, so be sure to download one of these tools and use it to remove your antivirus.
If removing antivirus software solves the problem, you must install different antivirus software on your PC. We made a list of the best antivirus programs for Windows 10 and we recommend that you consult it.
Solution 9 – Restart Windows 10
If all other solutions fail, you can reset Windows 10. Note that restart Windows 10 will remove all installed applications, so you will need to download and install them again. Restart Windows 10, you should do the following:
- As your computer restarts, restart your PC a few times. This should start the automatic repair.
- Choose Troubleshoot> Reset this PC.
- You can choose to Keep my files and Delete all. The first option will be installed Windows 10 again, but it will not delete your personal files and folders. The second option will delete all the files and folders you have on your C drive. If the first option doesn't work for you, you can always repeat these steps and choose the Delete all option.
- The reboot process will start now, so make sure you don't interrupt it.
If the reset option doesn't help, you can always do a clean reinstall and completely format the hard drive partition. Note that these procedures will delete some of your files and folders, so make sure you have a backup available.
