I have a lot of programs and software licences, so that would be quite a lot of work, but yeah, that might be the only option left... But to my understanding the BIOS issue happens before the computer even knows that Windows exists, correct me if im wrong.

Hello, TLDR: Random bluescreens at system startup and shutdown. Randomly couple boot cycles during startup after which the BIOS has to be recovered by pressing F1. Issue 1. For the past year or so i have had random bluescreens when starting and shutting down my system. I started googling the error messages from the blue screens, i don't have list of all of them but one common one is "Kernel Security Check Failure Error" and have done all the recommended measures, updated all drivers that i can think of, scanned for viruses, enlarged hibernation file, reseated RAM and SSD's, uninstalled old software... but nothing has helped. As a final resort i updated BIOS, this did not help either but intorduced a new problem... Issue 2. After the BIOS update i noticed that my Samsung 960 EVO 256 Gb was not visible in Windows. This happended because the M.2 changed to the wrong mode after the BIOS update, after changing the setting back the drive started to work again. But sometimes when i start my computer it does these ~2 second boot cycles for about 3 times, only then it goes to the black screen where it says "press F1 to recover BIOS settings", this does not happen every time, once i press F1 i have to change the SSD setting back. What could cause the BIOS to fail like this? Honestly I am tempted to just go and buy a new Ryzen system, but as my setup is still quite decent, i would appreciate if we could find a fix for the BIOS setting and bluescreens, which i think are related.
