I was checking errors in the event manager. I have found quite an amount of controller errors:
(translated:) The driver found a controller error on \Harddisk1\DR1. The last number varies DR10, DR3, .... and the Harddisk number varies between 1, 2 and 3
Is this the internal SSD or does this come from external hardrives that I removed without ejecting?
None of the other errors seem relevant. Some of them are known Windows issues. None match the dates pattern of the crashes.
The biggest problem is that the BSODs are so sporadic. Even if I re-install the system I can't run it in minimum state for a month not doing any serious work.
