CPU/Mobo Wierd Issue with 2 different PCs with similar configs

Hi all,

Have I recently built a PC for a friend with a very similar config as mine. The issue that I've faced is that while gaming the PC will shutdown immediately! No BSOD or anything, hard shutdown.

Specs

PC1
Ryzen 7 5800x
Aorus x570 Pro Wifi
Zotac 3080
RM1000x
32GB RAM


PC2
Ryzen 7 5800x
Asus x570 A Pro
Colorful Vulcan 3080
Antec HGC gold 850w
32GB RAM

Both systems have the latest BIOS.

This has happened at my place and my friends place too, so power should not be a concern. Neither of our places have fluctuations.

One thing I have noticed is, i have had it happen at strange but predictable times. Eg. A VERY special point in the game. Like Press X to exit the vehicle, and it would shutdown at the exact same moment. Or me toggling Vsync on/off. These are just 2 examples, but a lot of times the issues is unpredictable. The PC runs Furmark fine, so I don't think its a PSU issue.

One thing common in both PCs, both going to a TV via a Pioneer AVR (one TV is 1080p one is 4k). Even connecting it directly to the TV does the same for PC2, not tried this on PC1)

For PC1 the TV and AVR has been the same and worked with my old 1080Ti.

PC2 even has a UPS in the middle (even bypassed this, issue still persis)

Both PCs CPU temps are within limit. And strangely, the PCs will work just fine at times and then suddenly act up.

Happened on Win 10 and 11
Latest Drivers.

TIA.
 
A shutdown is a graceful switching off of a computer by using Start menu or by other means which goes through the proper software routine of closing all running programs and then shuts off your computer. If that doesn't happen and it just turns off like a power cut stop referring to it as a shutdown.

Now coming to your power supply verification. You just ran furmark and determined that the PSU is OK. That's not how you do a full load stress test.
Run both furmark and prime95 simultaneously to put load on both CPU and GPU at the same time. This will ensure you reach peak power draw by the machines and then see if it stays stable for like 20-30 minutes. If not then you know your issue.

Lastly, it could very well be an nvidia driver issues since in the past year the releases are terribly buggy with multi-monitor configs especially including TVs and when pairing HDMI with DP etc. Try experimenting with older drivers such as 512.95 or 517.48 or 516.94 these are some known good versions.
 
1. Please check if there anything logged in Windows Event Viewer.

2. Could you try loading the CPU when running FurMark simultaneously? Use 14 threads leaving two for FurMark to feed the GPU.

Let it run for a while to see if any transient spikes are triggering the OCP in the PSU. Both PCs have solid units which should be able to handle a 3080 easily but nevertheless we should verify.

While it's running, you can also check if the PSU rail voltages reported in monitoring tools are within spec.

3. Any kind of overclock or undervolt in use? Including PBO, Curve optimizer or game mode in BIOS etc.

4. Does the issue happen with a regular monitor connected directly via a known good cable? One of my monitors kept crashing my GPU sporadically when FreeSync was enabled. My PC would be frozen with a black screen or hard reset itself. It went away after replacing the HDMI cable. Try switching to DP if thats an option.

My bad, its a poweroff, like someone pulled the power cord. Strange thing with both PCs, the RGB stays on. Have run CPU and GPU tests but never together. Will try that.

You think a driver issue could be so nasty causing such a hard and dirty shutdown, id have imagined BSOD or crash to desktop. Problem is, these are GRDs so games like Spiderman and all need these optimised drivers.

Cool thanks will try the 14 thread thing. I too had my doubts on an OCP issue.

I've checked all rails in HWInfo64 logged to a file, no abnormalities there.

No OC. PBO was on, tried turning it off, same issue, kept PC2 in Eco mode still displayed the same behaviour.

So, my friend took his PC to A local shop (since he lives 2 hrs away from my place) where connected via DP PC had no crashes. So, he took the PC back home after testing and strangely the PC worked fine at his place for the next day n a half, the started giving issues again.

My RM1000x, brand new unit, died in a few days after being opened, it's in RMA atm. Don't know if something in the chain is messing things up. My system (PC1) has old but relatively high end Belkin HDMI cables, wondering if that's a problem too? I've ordered new 2.1 spec'd cables.

Don't have a DP display. But your case is interesting, can you elaborate on the issue of hard reset? Full PC would reboot w/o a BSOD? What HDMI cable was it? What resolution?

It was a Lenovo Q27q-10 which is a 1440p75Hz monitor with FreeSync support. I had lost the original cable so I used one given to me at work (Probably the box cable included with a BenQ GW2480) after which I started having issues.

It went away after I tried another HDMI cable that my father had (no branding on this, so no idea where it came from). It also worked fine with a cheap DP cable which I bought later.

When I say hard reset, the PC would act as if it momentarily lost power and then turn on by itself. Logs only recorded an unexpected power loss event.

Yes, i have come across similar problem with DP cable, coz the source of this problem is not easily discoverable, as our mind works only with PSUs, the fault is in the DP cable, as you all may know, the DP cable has bunch of high-tech wires inside to carry forward the data, and one of the wire is employed for power which may play the spoilsport, i replaced the DP cable with an expensive one, then onward its going good, By the way my GPU is gtx 1070...

No sir, we have. Not that much of an amateur ;)

well the above was the trouble with most AMD setups, people download motherboard drivers and think they are done.

On to the next step then :D

- Try all core 3.6GHz downlvolt at 1.25v at BIOS level, PBO would be off and with single RAM stick
- Try with diff ryzen processor
 
Try the problematic machine on a monitor and observe,
Few days back I installed nvme ssd and pc started behaving weird like unknown bsods etc. (Wouldn't mention deep on event viewer) Troubleshooted a lot and I feared that nvme takes precedence over sata so moved sata bootable ssd to channell 4 instead of 6 and boom the issues got resolved!
So check the storage configuration as well.

They are 2 different CPUs, buddy.

have you checked your motherboard bios for 12v and 5v voltages

All ok here, checked already :(
 
Than check power supply rails wherein your GPU pcie cables are connected on correct slots.every SMPS is differently connected internally so make sure both of your pcie for gpu are on different rails and your cpu eps too is on a separate rail or calculate and balance out the rails

I thought about this, to avoid too much load on one section of the PSU rail/output. Sadly, they do not mention this on the PSU section of either of the 2 PSUs so I woudn't know w/o opening the unit and seeing the circuitry, which i cannot do without voiding warranty. That said, I have tried putting the GPU ones far away from the CPU ones, but it did not make a difference.

Both those PSUs only have a single 12v rail so I don't think it should have any impact.
 
if you are having SSD/HDD do a checkdsk /f /r on all partitions .If you have HDD unplug and try to re create the scenarios faulty hdd are sometime the culprits.if this also doesnt solve the issue than you have to start isolating individual peripheral component.

Well than i would recommend keep all of your voltages on stock and than underclock your cpu to lets say 2 ghz and no autoboost etc same for CPU ,GPU rams and what not .Than re create the scenario. If it works .Than bring back your cpu to stock settings re-test . oc /whatever you were running it tune it retest per peripheral which are not runnig at stock settings.
