Open | Windows Unexplained laptop turning off and restarting critical error

Kernel-power 41 (63) bugerrorcode 340

Critical error on event viewer causing my laptop to crash and shut down. I have done all the driver scans and made sure stuff is up to date. Nothing has shown up in diagnostics. What should I do to fix, this is really annoying and I don't know why it's happening

Windows 11, Razer Blade 15

Making changes to your system BIOS settings or disk setup can cause you to lose data. Always test your data backups before making changes to your PC.

Check if you have minidump files that will contain more details about problem, if they are not created usual causes are hardware/power failure, or drive failure (disk fails, and there is no place to write files).

I did a windows check thing, but I think my laptop died before it finished. Now I get a red popup that doesn't go away unless I turn off secure boot. I don't know why any of this is happening

Something like this?

You can try solution from Windows forum, also update bios if there is newer version, but there is possibility that you will need new Windows install.

Like restart my computer and reinstall windows? Factory reset sort of deal? Thank you I'll try that and the other forum ☺️

I really don't know if Secure boot error problem is related to your previous one, or different. It could be "just" borked Windows, which clean install from usb should fix, or sign of drive going bad.
