that first dump is Xorg going through FatalError -> OsAbort, so I'd look for the fatal error message before treating it as evidence of a bad motherboard. it's also only about four seconds after that boot's kernel message, not necessarily one of the freezes you experienced later.

for that specific event, try: 

sudo journalctl -b 8bce1c24607842e2b55a2307361f3080 --since "2026-10-03 20:50:00" --until "2026-10-03 20:50:30" --no-pager

for the next actual freeze, note the time and compare the Xorg log and kernel journal around it. save /var/log/Xorg.0.log.old promptly if LightDM restarted X, as later restarts can replace it. the lines before Fatal server error: are more useful than the abort stack alone. does it log you out to LightDM, or does the whole machine stop responding, including a text console/SSH? those are different failure paths to investigate.
