I did the memtest twice: yesterday two pass with 0 error and today two
pass with 0 error, all together this takes 8 h 30 min.

So I can tell that the RAM is all right on this desktop PC box, right?

What do you advices me, what to do further?
Should I try to investigate the sda4 error or not?
Can I do something with the nvidia error?
Or just do a fresh install of my Arch system ( but first backup /etc/
and $HOME directory with all my setup? )
