I was using the machine system froze and restarted, tried to find some relevant logs with no luck. I see some KDE and baloo core dumps but nothing to explain a hard reset like I experienced. Sound and screen froze, display went black and the system rebooted.

Please use pastebin.com … it seems pastebin.pl is down.

Did you try a different kernel? A LTS one perhaps …

Pastebin.com does not hold the whole info, so I posted in:
Ubuntu Pastebin

The older kernel had issues with the Nvidia drivers and wont even boot but I will try it again.

Running 5.4.89-1-MANJARO now. Still as I can’t reproduce the issue I don’t know if it will happen again.

Keep an eye on your T° because that sounds like an emergency overheating shutdown.

psensor is a good utility to do that.

pamac install psensor

is the Manjaro command to install that.

:crossed_fingers:

I just added a widget to monitor it is such solution oki? But I don’t think it is the issue I game on windows and this has never happened Screenshot_20210202_160459

Windows is not Linux. :grin:

I’m not saying overheating is the problem, just that what you see is similar to that.
If it would not be, a memory test would be in order as that is the second most common problem for the symptoms you have.

If it happens again, provide the last relevant portion of your previous boot log:

journalctl --system --boot=-1 | tail --lines=X

Where X denominates the relevant number of lines that’ll help us help you.

Looking through 6000+ lines of log file is just not a good fit for a simple forum.

:sob:

Just ran the memtest for 8 hours no errors were found.
