[SOLVED] PC turns off randomly without warning

nyker.emil · Dec 6, 2018

Hey there. The past week ive started to run into some issues with my computer. It randomly turns off without warning, the displays goes black and the computer reboots all by itself. I tried to look at core temp to monitor the CPU until it went down, and they dont exceed 45 degrees celcius under heavy load

the odd thing to me is that the first time it happened, i wasnt even playing games, or doing some sort of heavy tasking. About a week ago i was working on my exam project, when the computer shut itself off. i thought the plug was just loose or something so i pulled it out and put it back in.

today it has happened twice. Both during the first 5 minutes of a league of legends game. The odd thing is that it isnt every single time i play a game. between the first and second shutdown, i was able to play 3 games of league, and one game of counter strike, again looking at temperatures, and not seeing any issues

Can it be because of my power source itself? Since i am kinda taking a lot of power from one socket in the wall. But at the same time, its been like this for quite a while. I would be surprised if it started happening now

Specs:
Intel core i5 6600k, not overclocked atm
MSI GTX 1060
MSI B150A GAMING PRO, Socket-1151
Corsair cx600w
2 x kingston 128GB ssd
1 x seagate 2TB

My canned random reboot Rant
Random reboots are usually caused by the PSU, the RAM or software AND in that order of likely-hood.
PSU - If you can borrow/swap a PSU for testing. sibling/friend you can swap out the PSU and each system will be testing the other.
RAM - run the system with one stick of RAM see if stability returns if not Test all the RAM with memtest 86 for three passes or overnight. if you get no 0 errors after more than three passes the ram is good. with the random reboots I would suggest running this test after the PSU swap or after the PSU has been cleared.
Software - Drivers or other issues can cause reboots. Boot to a linux distro on a USB drive. mint linux will boot to memtest86. you can run the OS from the USB and await reboot.
end canned rant

What annoys me is that it doesnt seem like i can just "provoke" the shutdown. My pc was on all night yesterday with videos on youtube etc. But randomly just having the pc and a word document open seemd to make it shut of aswell. I havnt been able to consistantly provoke it. Some league games it works fine, the next game it crashes. I have checked eventviewer, but no dice. Only that the system had restarted without being properly shut down first

that what makes this gremlin a pain in the donkey to nail down.

the cx600m does not have the best reputation in the world. as an owner of that same PSU I would start looking there

Yeah i was about to say the PSU was bought back in 2013.
I have atleast completly cleared the concern it was a heating issue, since everything is currently dust-free and cleaned, good temperatures all round and im still having issues

I was wondering, due to where i currently live. Can it also be an issue pulling that amount of power from the wall? Our router and other stuff is also connected to the same plug in the wall. Even tho i don't believe so since the light also powered from the same plug did not turn off during the first shutdown

nyker.emil :

no. the power supply is not consuming 600W all the time. less than 400W at maximum is what your system draws, add the inefficiency of 20% and your looking at 480W at the wall, and only when at maximum.
the vast majority of the time it is well under 200W.

the cx has a 5 year warranty, 2013 times up.
