I'm having issues trying to understand why my system randomly halts or reboots. Here are the specs of my system, retrieved using neofetch:

I'm using this machine to run ML algorithms using TensorFlow. However, I've been monitoring CPU and GPU temperatures and it doesn't seem the system halts because of reaching a critical temperature. One thing to take into account is that my system is not upgraded to the last version (I have used the hold command to prevent my kernel from upgrading), since I had incompatibilities between the newer kernel versions and my code version.
I have taken a look at syslog for the time of the last unexpected reboot, and this is what I have found:

I have difficulties in understanding all of the logs but, from what I've seen, it seems like the process sddm crashes and then systemd reboots my system. In other cases, my computer does not reboot but rather shutdowns incompletely. By this I mean my screen has no signal but my computer is still on (the lights, CPU, etc. are on) as if it had not completed the shutdown. Thus, I don't know if sddm crashing is responsible for all the reboots, shutdowns or none of them. Another possible cause could be small blackouts, but in that case I don't know if my computer would completely shutdown.
Edit:
As Daniel Kelley suggested I'm also uploading the contents of the /var/log/kern.log and /var/log/dmesg files:
