If removing the antivirus didn’t resolve the issue, it’s because many programs, including antivirus, leave behind files and registry entries after they’ve been removed. Even these files can cause BSoD errors thus, it’s critical to remove any files linked with your antivirus with a professional removal application. Most antivirus software firms make these programs accessible for download, so be sure to get one.

You must use suitable drivers for Windows 10 to recognize and use your devices. Your drivers may not operate well with your PC if they aren’t compatible with Windows 10, or if they are just obsolete or buggy, and you’ll get the ACPI BIOS FATAL ERROR Blue Screen of Death problem.

Solution 2: Install the newest Windows 10 updates and update your drivers

These kinds of errors usually indicate which file is causing the crash, and with a little digging, you may quickly identify the driver that’s causing the issue. To resolve this issue, go to your hardware manufacturer’s website and download the most recent drivers for your device. If you can’t figure out which driver is causing the issue, you’ll have to update all of them simultaneously.

Drivers are updated automatically

It can take a long time to look for drivers on your own. As a result, we recommend that you utilize a tool that will perform this task for you automatically. Using an automatic driver updater will save you the time and effort of manually looking for drivers, and it will ensure that your system is always up to date with the latest drivers.

A third-party program will assist you in automatically updating drivers and preventing PC harm caused by installing incorrect driver versions. Our team determined that this is the best-automated option after doing multiple testing.

It’s just as vital to obtain the latest updates through Windows Update as it is to download drivers. Windows 10 has several faults with both hardware and software, and these issues might result in Blue Screen of Death errors.

It’s critical to keep Windows 10 up to date with the latest updates if you want to avoid problems like these. Many of these updates address hardware and software issues. Still, they also provide new features and security enhancements, so we strongly suggest you to download the most recent updates if you want to keep your PC safe and error-free.

If the ACPI BIOS FATAL ERROR error is generated by third-party software, you should be able to resolve it by resetting Windows 10. Remember that rebooting Windows 10 will delete all files and folders on your C partition, so make a backup of any crucial files before proceeding.

Several users stated that their laptop battery was the source of the error and that the problem was resolved after replacing the battery.

Solution 8: Verify that your gear is in good functioning order

Almost any hardware component can cause this issue, so if you’ve recently installed any new hardware, we recommend removing it or replacing it to see if it solves the problem.
