It's an AMD (GPU, not CPU). Anyway, I am allergic to proprietary
software :-).
Nothing in any of the Xorg.*.log*'s jumps out at me.
~user/.xsession-errors is empty.
Maybe we can catch log entries before it completely dies. Bring the
system up in single user mode, then edit /etc/systemd/journald.conf.
Find the line:
#ForwardToSyslog=no
Change it to:
ForwardToSyslog=yes
and save the file. This should cause journald to forward log entries
to the old system logger. Reboot and force the crash. Hopefully, the
messages will get logged to /var/log/messages before you lose the log
daemon.
Reboot again to single user mode and look at /var/log/messages to see
if you caught it. Change the line in /etc/systemd/journald.conf back
to put things back the way they were.
NOTE: I've not tried this myself. Others have told me it works and I'm
just passing it along.
