Hi guys, I do not have any more crashes. After all these steps from this tread, my system was still lacking stability.
But several months later I got new drivers for almost everything, and new bios/uefi - finally my pc works and I can play DCS in VR all the time.
Please close this thread as resolved, and thanks to everybody helping me 🙂
Ps: later I found out all that was Intels fault; my cpu is 14600kf, one of Intels with "wrong" factory settings. I had about 50-100 BSODs and forced restarts.... I can only hope nothing else was damaged because of this.
