random system restarts

[spark sonnet]

hi, ive been experiencing random system restarts for the past few weeks and one just happened now
can someone help me debug, im not that good at reading kernel/system logs and understanding them

[agile bramble]

Check the output of journalctl -b -1 -e??

[spark sonnet]

what should i look for in there? like i said im not very good at reading the logs and understanding them

im not too familiar with journalctl, and also running that command right now doesnt show anything from back when the shutdown happened, im seeing logs from right now

[agile bramble]

Share the output.

[spark sonnet]

actually i guess i was wrong they werent from now

[agile bramble]

Looks fine.

[agile bramble]

Run sudo pacman -S stress lm_sensors and after that run

stress -c 4

and run in another terminal.

watch -n1 sensors 

[spark sonnet]

Ok what then

[dire root]

Its so that you can watch if the CPU heats up to the point of triggering a safety emergrncy system shutdown.

[spark sonnet]

Nothing has happened so far

I've been stressing my cpu for no reason? 😭

[dire root]

I feel ALPHA simply wanted to rule out the usual culprits.

Im assuming you have not messed with scheduled tasks or anything on your system right?

like cronjobs and all that jazz?

This is a bit hard to find the cause tbh it could be a lot ofthings and the logs looks clean

[agile bramble]

There is a reason for that, to make sure it is not the CPU in the first place.

[agile bramble]

Run stress -c 4 -m 2 --vm-bytes 512M and open another terminal and run watch -n1 sensors??

[spark sonnet]

I haven't

[spark sonnet]

What should i be looking for

my pc just restarted like 3 times in a row

as i was opening firefox one time and when i switched tabs on brave once

i feel like my pc crashed many times when switching tabs on brave

i use brave from snapcraft, to run it in another sandbox

If you boot the arch iso and do a memtest86? Im almost wondering if its a RAM issue.

Does your machine have any kind of auto-OC applied in the BIOS? (Beside RAM XMP)

[spark sonnet]

ill see tomorrow, its late now

thanks

[agile bramble]

What DE you use??

[spark sonnet]

dwm

the problem is getting kinda worse, it used to happen before but not so often and now it keeps happening

id really like to find out the problem because im afraid of my filesystem getting corrupted or something during one of these restarts, idk what could happen

here is the output of my fastfetch:

[spark sonnet]

also im not sure what im supposed to look for/watch in the watch command

nothing happened so far

[agile bramble]

Output of cat /etc/locale.conf??

[dire root]

Did you look if any OC was applied and did you at the very least test your RAM to rule out hardware instability?

[spark sonnet]

# This is the fallback locale configuration provided by systemd.

LANG="C.UTF-8"

[spark sonnet]

How do i test my ram

when i bought this pc i had problems even starting it up so i had to get ram replacements and play with the ram slots to get it working

i dont think theres any overclocking..

[spark sonnet]

can i not just run memtest86 on my system normally

or does it have to be from arch iso

[dire root]

When you boot the iso, actually before booting the iso theres a menu with memtest86

Looks a bit like this.

Probably more like the 2nd picture though.

[spark sonnet]

Ah ok, I'll run it and post the results here

[spark sonnet]

hi sorry for the late reply, it passed

i got "PASS" at the end in green

[spark sonnet]

i recently saw my psu cable burned and 2 pins in the psu cable port burned, i replaced the psu and i also had to put thermal paste on my cpu

i guess that solved it

[agile bramble]

Does it work fine??

[spark sonnet]

so far yes

[agile bramble]

Good.

[agile bramble]

.s solved
