Hi,
I'd really appreciate some input here, the machine seems to be trolling me
I built a PC for a friend recently, specs are at the end of the post.
The machine was quite happy for two weeks after I built it, he was loving his new gaming PC. This was until Tuesday this week when he sent me a message saying it was turning itself off, then was unable to POST and continuously went into a reset cycle before any display loads. He's not hugely technical so I took that to mean it was cutting off suddenly as if power had been removed as I would usually expect to see, I got him to check a few things over the phone but ultimately it proved fruitless so I went over last night to take a look.
When I got there the machine had been totally unpowered for about 24 hours and when I powered it up it seemed fine, but he said it took a while after it'd been off for it to show the issue again so we hung around for about 40 minutes and a few runs of benchmarks trying to stress things into faulting again, the problem showed itself. However this was not the traditional 'reset' style shutdown, it was an actual graceful shutdown as if someone had hit shutdown on the start menu, except this was sponaneous. Windows said "windows is shutting down" etc.
At the time this happened the processor had not exceeded 45C, GPU had not gone over 65C, and the hottest mobo temp was at around 52.
The PC then went into a reset cycle like it was unable to post, so I powered it off and left it for a few minutes and tried again, at which point it told me "Overclocking failed" etc and to go into BIOS to confirm settings, which I did, and the PC then booted back into windows. Within a few moments of being in windows again, though, it again spontaneously but gracefully shut windows down again and went into the reset-before-POST cycle again. If I removed mains power for a few moments and switched it back on (but not press the power button) the PC would try and start all on its own, but still fail.
At that point I switched everything off and removed all but one DIMM (tried each in turn in a different slot), which had no effect, and took the GPU out - again, no effect, trying to minimise as much as possible the hardware in there didn't seem to help.
I should also add that it reset while idle in the BIOS, too, so I can rule out software packages causing a reboot. A momentary press of the power button in the BIOS would instantly turn off, and in windows would trigger a graceful shutdown, so it feels like that is what is getting sent, except the button isn't being pressed, and it doesnt explain the lack of POST immediately after it.
If anyone has any suggestions I'd love to give them a go when I get back from work tonight as I just don't know what to do at this point. I plan to try a different PSU tonight, but I can't see how a PSU could trigger a soft-shutdown command to the OS. I do not have another CPU to try, and all 4 sticks of RAM can't be bad, though I'll try a known good stick from my spares too.
PC spec:
Mobo: Asus Maximus V Gene (1204 BIOS)
CPU: 3570K
Mem: 4x4GB Corsair Vengeance 1866MHz, XMP enabled in BIOS, this is the only performance setting in BIOS altered.
GPU: Palit GeForce 670 Jetstream
SSD: 2x M4 128GB (one OS, one for caching of HDD)
HDD: 1TB WD Black
PSU: Seasonic 760W Modular Gold
Monitor is connected via motherboard HDMI, iGPU enabled in bios.
Bios was on 0813, but I updated to latest (1204) and it has made no difference.
Apologies for the long post, but its a weird one!
