PC shuts itself off, as if pulling out the power chord

[Rubble]

Hi guys and girls,

As per title, the PC just randomly turns off, but there doesn't seem to be any pattern. Specs are as per my sig and everything runs off an RM750x which is still plugged in to a surge protector. My suspicion is that something happened during load shedding as its only happened the last few weeks.

It used to originally crash only during updates through the blizzard client or playing warzone, so i thought it was software related but it's since started doing it even after a clean boot where i don't launch either.

The surge protector looks good still, voltage readings in the bios all look good and are within their safe parameters. I'm not sure if there is another way I can test without a PSU tester as with a multimeter the readings do look similar to what I'm seeing in the bios.

I've also run memtest (the free version with 4 runs) 3 times as well as stressing the CPU using the CPUZ stress test and prime 95, and using unigine benchmarks on loop and furmark for GPU stressing.

My last resort is reinstalling windows within the next week or two.

if youre using a ssd, check how much data gas been written to it.

My poor 250gb ssd has had 20tb written to it already from the swap file destroying it.

Could be your hard drive?

i see you have a RIPped 1080 - did this happen at a similar time to your PC giving you issues?

Certainly sounds like a power issue or possibly a short. Check all cables are securely plugged into the motherboard (and PSU as it's modular).

Its new-ish with only ~6,3tb of the total 650tbw its rated for, though I've had a new SSD go bad before so i wouldnt be surprised. I did a block scan using HDtune as well and all looked good

The 1080 was last year sometime so I've been using a borrowed 2070 super. I've reseated just about everything but it can't hurt to do the PSU-end of the connectors as well so will give that a shot

Also, is there a correlation between it shutting off randomly and load-shedding? I've noticed my PC also shuts off instantly when load-shedding happens and I've traced the issue to inadequate power from the wall plug.

It's a new house i moved in to 2 months ago and until load shedding everything was 100% so I'd assume the sockets themselves are fine. I don't OC so the power draw is pretty low I imagine so I don't think it would be draw as my PC and monitors are the only things plugged in to the socket for a total of 500-550W.

I don't know if its a dumb question but is there any way you tested what the wall plug could provide? I cant think of any other way aside from just plugging stuff in and seeing at what point it trips

How old is the PSU? If it's not under warranty you could try opening it up to see if any caps are swollen? In my troubles like this it's always been an aging PSU that just couldn't give quite as much juice as was needed. Then the system shuts itself down for safety. I'd only do this if you're technically inclined though.

The other thing you can do is to check windows logs, if it is an app or specific piece of hardware you'll likely be able to find something linking to it in the error logs. Should also not be too much work if you check the logs right after a shutdown. You'll have a good idea of the time stamp on the crash so you just look from there in the logs.

It's fairly unlikely but not impossible that the sockets are the issue. I'd suggest just trying it on a different socket before trying to open stuff up, maybe one that's on a different switch on the main board.

If you are struggling with the logs send me a PM and we can arrange a time to take a look together. we can just check remotely.

I was just kidding bru. When i have load-shedding I have no power out the socket. Then when load-shedding ends, I do have power out of the socket. Neither an electrician nor Eskom has come up with a viable solution yet, something to do with coal shortages and tenders.

You mean retaliation because they can't buy a new BMW this quarter of the year due to not getting a R12m bonus?

Something like that, yea.

Need more information ....

When your PC turns off

* Does the PC restart on its on ?
* Do you get a error message ?
* If it goes off like pulling out power chord lol ? if you press the power button . Does the PC come on ? no problems ?
* Is any message in the bios ? When you turn PC on ?

Its 3 years old but has 10 year warranty and looks all good shining a light through the fan grate, trying different ports on the PSU as well to see if theres any difference.

The event logs show nothing though, no errors at all just when the PC boots up it has the usual warning that the system hasn't cleanly shut down (

You never know haha, got to cover all my bases. Just figured you had back up power

Forgot to update this, reseating all of the power connectors did the trick, despite not being touched for months. Thanks to all who helped.
