Last few days I have many unexpected reboots of my Ubuntu 18.04.
Visual effects:
– work as usual (docker, intelliJ, firefox)
– unexpected halt
– fans goes crazy
– push restart button
– PC start normally
LOGS
Based on answers and comments from:

I did small investigation. In syslog I observe that (yesterday):

Suspicion
First was too high temperature. Summer, could happen. But I work in room where I have no more than 20°C and sensors never show more than 45°C (on both CPU and GPU).
Second is CMD (command -v debian-sa1 > /dev/null && debian-sa1 1 1) and that all restarts happen at HH:55.
Then I found Machine stops suddenly, Only hard reset can help
but I have 48GB of RAM and that was very old Ubuntu so it should not be a reason.
Questions
It is simple – Why my PC reboot? Is there any other checks/wokr that I could do to find the reason?
