[SOLVED] Machine Randomly Powers Off No Blue Screen

[Stormer3]

Greetings

My system will randomly power off with no warning (like you unplugged the power cable) soon after it will reboot (it always reboots). Heat is not a concern temps do not exceed 70C on any component plus its a dual radiator setup with 1 extra case fan (5 fans total + PSU Fan i guess) . This system was stressed tested multiples times the longest being for 7 hours (Aida64 system stability test all boxes checked and Heaven Benchmark for GPU). The oddest thing is this issue wont occur for days or even weeks. But one day idle or on full load it will just power off. The system is hooked up to a UPS that 1500 va or like 960-980 watts my PSU is a 1000 watts (clean power isn't a issue voltage regulation).

Finished Windows Memory Diagnostic: PASS

Edit: Tightened CPU Block was a little lose and re-seated all RAM moved each stick to a different slot. Checked 24 pin and all other connectors. Issue has not occurred again however its only been a hour. This happens rarely as mentioned before. Still looking for feedback if anyone has any ideas, maybe additional ways to find a fault.

Edit: Issue did reoccur this time system power cycled 3 times in a row. Then just acted normal again.

If any of you have any thoughts or ideas it would be much appreciated all I have is kernel power failure event message (which doesn't really tell you much if anything).

"Quick and dirty" answer:

Hi ! Was on diff business but immediately thought (older configuration) only thing that did/does that to me was computer thinking/real GPU overheating->instant shutdown. I solved by picking overclocking program and turned GPU to lower than defaults. So, follow temperature (compared to BIOS temp max if applicable). Worth trying ?

[Edit: yes, read you've followed temp etc, but did on me same-no difference when idle or not, just shutdown. But as said, only thing that's ever done it to me, edit2: no, didn't have too hot GPU (said logs) but haven't shutdown after that. Also MSI mobo. I clock normal when playing, when idling on 24/7 I load set to lower GPU almost everything, haven't diagnosed which part did the problem to me]

Thanks for the suggestion but i don't want to down clock my GPU it's a 2080ti

 

[Sukka]

Yes, but the point in clocking down is you can go to store where you bought your stuff and say it's faulty, NOT that you'd be powering it down all the time.

Well... normally this points to a psu issue, but that Corsair HX should be a pretty good unit, unless you bought a lemon...

Looking at the rest of your specs though, there is one particular red flag, that is also a cause of reboots:

RAM:
G.SKILL TridentZ RGB Series 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 3200 (PC4 25600) Desktop Memory Model F4-3200C16D-16GTZR (2 Sets 32GB Total)

2 Sets

You probably lost the mixed ram lottery. Leave the first kit in(I hope you kept track of which sticks went with which kit!), and run tests with the following:
-Memtest86
-Prime95 Blend Mode
-AIDA 64 Memory Test

 

[Stormer3]

So just so I understand the individual RAM sticks that come in sets are linked in some way? Or are you saying one of sticks are bad? Or are they just in the wrong slots? I really dont understand RAM at this level I can run all the tests thats easy. I really appreciate the response just want to execute this properly.

1)Ram is tested and guaranteed to work as sold.
-You bought 2 separate kits, which weren't certified by the manufacturer to work together.

2)Different kits of the same brand and specs can still fail - it's simply the combination with the highest compatibility rate among mixed kits.
-Even though you essentially purchased the same kit twice, they should be fine together... in theory. If they happen to come from different batches in production though, compatibility would be questionable.

3)The first suspect in such reboots/restarts is normally the power supply - refer to what I posted previously about it.
-Freezing/crashing, stuttering, BSODs, and reboots are symptoms of incompatible kits.

So, you need to test with one kit - again, assuming you haven't completely mixed the sticks up by now...

 

[Stormer3]

Oh wow I didn't know that was how it worked at all. Been up with no problems for about 4 days now on. I did switch all the sticks around so finding out will be fun. Maybe use serial numbers to find out somehow. Re-seated everything as well. If the problem occurs again I will definitely return both sets and by a set of four. Thank you for the advice I've run so many tests and nothing has shown any issues. Your solution seems like the only thing at this point that could be causing the problem.

I'm having the same issue and I to have a z390 motherboard. Did your issue turn out to be the RAM?
