No Nvidia related error logged within last three boots in the log.
How did you call this, if it’s not Nvidia related ? :

Seen it, that’s in an old log from febuary.
Sorry you’re right.
But the symptoms are always the same for all the last crashes: locked screen in a situation as shown in the picture attached to #17 post.
Hmmm, I’ve said it before, something is dying in your PC, don’t know what, though. Previously, errors were logged but always different ones and the last occurrences, nothing got logged, PC froze right away. So this gets worse. On the next time, please run right after reboot
sudo journalctl -b-1 --no-pager >journal.log
and attach that to have the complete log.
Did you check for faulty memory by removing it, meanwhile? Or tried reseating/reconnecting the graphics card?
I just ran memtest86+ at boot for 50mn, without any error.
I thought it was a good idea because i’ve added 8Gb to my computer a few weeks before the problem started to occured. But that was not my only change because I switched from Debian to Arch in the same time.
