Fix – ACPI_BIOS_FATAL_ERROR Windows 10 error

Solution 1 – Remove problematic applications

BSoD errors are often caused by third-party applications, therefore if you installed or updated any applications before this error appeared, we advise you to find those applications and uninstall them. We have to mention that antivirus programs and firewall can often cause these types of error to appear, therefore we advise you to remove your currently installed antivirus and check if that fixes the problem. Bear in mind that you’ll have to remove all third-party antivirus programs that you have installed since almost any antivirus can cause this problem to appear.

If uninstalling the antivirus didn’t fix the problem that’s because many programs, including antivirus, tend to leave certain files and registry entries after you uninstall them. Even these files can cause BSoD errors to appear, therefore it’s crucial that you use a dedicated removal tool to remove all files associated with your antivirus. Most antivirus companies have these tools for their software available for download, so be sure to download one.

Solution 2 – Update drivers and download the latest Windows 10 updates

In order for Windows 10 to recognize and use your hardware, you have to use appropriate drivers. If your drivers aren’t compatible with Windows 10, or if they are simply outdated or buggy, they might not work well with your PC, and you’ll encounter ACPI_BIOS_FATAL_ERROR Blue Screen of Death error.

These types of errors usually tell you which file is causing the crash, and with little research you can easily find the driver that is causing this problem. To fix this error all you need to do is to visit your hardware manufacturer’s website and download the latest drivers for your device. If you cannot find which driver is causing this problem, you’ll have to update all drivers by using the same method.

Update drivers automatically

Searching for drivers on your own can be time-consuming. So, we advise you to use a tool that will do this for you automatically. Using an automatic driver updater will certainly save you from the hassle of searching for drivers manually, and it will always keep your system up to date with the latest drivers.

A third-party tool will help you update drivers automatically and prevent PC damage caused by installing the wrong driver versions. After several tests, our team concluded that this is the best-automatized solution:

Solution  3 – Run the Hardware Troubleshooter 

Now, let’s try with Windows 10’s built-in troubleshooters. The first troubleshooter we’re going to try is the ‘unified’ troubleshooter from the Settings page. You can use this troubleshooter to address all sorts of issues within the system. Including BSOD errors.

  6. After the procedure is finished, restart your computer.

Solution 6 – Reset Windows 10

Windows 10 reset is similar to clean install, and if the ACPI_BIOS_FATAL_ERROR error is caused by third-party software, you should be able to fix it by resetting Windows 10. Bear in mind that resetting Windows 10 will delete all files and folders from your C partition, so we strongly advise you to back up your important files. After backing up your files, you should also create a bootable USB flash drive because you might need it to complete this process. To perform Windows 10 reset, do the following:

  1. Restart your computer few times during the boot in order to start Automatic Repair. Alternatively you can hold the Shift key on your keyboard and click the Restart button.

  4. Follow the instructions to complete the reset process.

After you complete Windows 10 reset, you’ll have a new installation without any third-party applications. If the error appears again, it means that the issue is most likely caused by your hardware.

Solution 7 – Check your battery / power supply

Sometimes errors such as ACPI_BIOS_FATAL_ERROR can be caused by your power supply, so you might want to check if it works properly. Several users reported that the cause for this error was their laptop battery, and after replacing the battery the issue was fixed. If you don’t own a laptop, we strongly suggest that you check your power supply unit.

Solution 8 – Check if your hardware is working properly

Almost any hardware component can cause this error, and if you recently installed any new hardware, we advise you to remove it or replace it and check if that fixes the error. If the problem still persists, it might be caused by faulty hardware, therefore we advise you to check all major components such as your motherboard, hard drive, graphic card, network adapter, etc.
