Can't figure why my system reboots on it own

Hi,
my system reboot automatically and I can’t figure out why. I was able to find a log:

Nov 29 10:33:23 linux-tdi2 dbus-daemon[838]: dbus[838]: [system] Activating via systemd: service name=‘org.freedesktop.NetworkManager’ unit=‘dbus-org.freedesktop.NetworkManager.service’

I was unable to start my firewall either.

I think you should describe a bit more detailed what you mean with “boot on it’s own”. For me it means that the system while switched off and you not touching it, spontaniously switches on and boots. Either please confirm this or explain what happens.

Spontaneous reboots are most often a hardware problem or because the unit is over heating. This unit could be over two and near three years old and if it has been running 24/7 for a long time, it may need a cleaning and its cooling fan may not be working properly. If the unit was clean and the fan working properly but with a lot of run time, I might suspect a memory problem of some sort. It is an unusual computer to use as a desktop though I don’t know what you are doing with such a rack mount 1U sized server PC. I am not a big fan of using 32 bit either as not so much problem solving may go into that OS, but with only one GB of memory, it may be the right one to use. If one could afford to go up to 4 GB, you could switch to 64 bit for sure, but its just speculation on what might be wrong now.

Thank You,
