Yes, I understand that I show very little info, but I don't know what should I show, I was asking about it in my post - what can I show here to get help?

Per your suggestion, I brought system up, switched to console tty1 and stopped lightdm service. Then I just left system on overnight and in the morning I saw many soft lock up messages on the console. I tried sudo reboot, but it got locked and did not work, see log below:

Aug 13 10:01:30 XPS-8700 kernel: [40741.481197] NMI watchdog: BUG: soft lockup - CPU#5 stuck for 22s! [reboot:4965]

I am not sure if stopping lightdm service was enough for this experiment. Any suggestions, please?
