I've been using Ubuntu 18.04 for several months, maybe a year. But since last July my ubuntu started to reboot randomly.
The command last reboot outputs the following
reboot system boot 4.15.0-55-generi Sun Aug 11 14:32 still running
reboot system boot 4.15.0-55-generi Sun Aug 11 12:44 still running
reboot system boot 4.15.0-55-generi Sun Aug 11 12:39 still running
reboot system boot 4.15.0-55-generi Sun Aug 11 12:01 still running

I thought it was one of my startup applications or any google chrome extensions doing weird things. I noticed that my computer rebooted when watching youtube videos or while idle after startup.I have disabled all my startup applications and all the chrome extensions I installed recently; I left the extensions I've since since forever. However my laptop keeps rebooting.
I also use spacemacs in server mode I disabled it thinking it can be due to intensive use. It didn't solve my issue.
I have my installation up-to-date.
It can be the fans, but Which log do I check? Also, I don't think the fans are the problem because my laptop doesn't reboot so often.
Any help to troubleshoot this will be appreciated. Which logs should I look into?
