How to Fix NO_EXCEPTION_HANDLING_SUPPORT BSoD Error?

I’m experiencing a Blue Screen of Death (BSoD) with the error code NO_EXCEPTION_HANDLING_SUPPORT on my Windows system. The crash occurs suddenly and causes the system to restart, sometimes preventing Windows from loading properly.

I would like help with the following:

What troubleshooting steps can I take to resolve this issue (driver updates, system file checks, hardware checks, etc.)?
If Windows becomes unbootable due to this error, what are the safest ways to recover important data before attempting major repairs or a reinstall?

Any advice, solutions, or real-world experiences would be very helpful.

On Windows 11 especially, firmware issues can absolutely trigger these crashes even when everything “used to work fine.” I’ve seen outdated BIOS versions and leftover overclock profiles cause random boot loops and blue screens once Windows updates security features under the hood. Resetting BIOS to defaults and updating it for your exact CPU is a smart first move. For data safety, using WinRE or a Linux USB to copy files is the least risky option, and I’d only suggest something like Stellar Data Recovery if the drive won’t mount or the files are clearly corrupted. Otherwise, fixing the firmware side usually brings the system right back.
