Random Computer Shutdowns? Tests ran, need ideas?

Hi,

I'm assuming you can see my system specs so i'll go on from there.

I built this computer about a week ago and everything is fine with it bar that it likes to shut down at random intervals. Normally when playing games. It gives no warning of the shutdown, it just instantly turns off/cuts out, and restarts again.

Now, My CPU is overclocked, as is the ram (They are both designed to be) And i've ran both prime 95 (24 hours) Intel Burn Test (10 times different stress levels) AND MemTest (16 Hours) and all have came back fine with no errors. I've had my temps checked and monitored and they're fine (I'm cooling using 4 120mm fans + a corsair h100i in push/pull cofig) so no TJMAX shutdowns. I've checked the power supply, and tested it running on obviously all these stress tests AND computers running xeon chips with higher power consumption than this 3930k rig and its been fine. (Power supply = Corsair AX850)

SO, the conclusion i've finally came to is windows. May be corrupted files etc. I've ran "SFC /Scannow" in my cmd window at admin level and it showed corruption/errors which since updating with recommended updates and scanning again have been fixed.


I'm sorry to be so long winded i just appreciate people need information to remedy problems so i'm trying my best to bring you guys up to speed.

If anyone could offer any help it would be appreciated.

Thank you.

Just a bit more info,

The games the computer cut off during were World of Tanks and Skyrim. Both running at max settings. I was however (in some downtime) able to complete a play-through of Bioshock - Infinite (16hours) without a single hiccup, and this included tabbing out for chrome etc when needed. It also plays GTAIV without issues, and battlefield 3. All games are ran on maximum settings on a 1280x1024 screen.

I'm pretty sure it's not a temperature problem. I've checked countless times with many programs and they all show temps being fine. My cpu peaks at 68/69 under maximum load and never goes over, and my GPU peaks at around the 65 degrees Celsius mark, which is also ok.

To be honest i've ran all these tests and the only thing i can think of doing now is playing skyrim/WoT till it crashes and going from there. I have done as you've suggested Kaktussoft and disabled automatic restart. Maybe this time if it does crash i'll be able to have something to report back with.

>> I've had a look in my bios and using ROG CPU-ID had another look at my voltages and my core was running at around 1.35, which ive determined a bit low for the 4.5ghz overclock. Would this ring true if my cpu didn't have the required voltage it might shut off?

EDIT: I've now set voltage to 1.38.

Just strange how its in game and not during extrem,e stress tests..

BTW, all my graphics card drivers are up to date, and it IS seated properly withing the PCI3 slot. It has the latest full release drivers from Nvidia, not beta or alpha ones.

The only thing i can think of now is either that, or my windows install is indeed corrupt. Sparking me to reinstall it again if all else fails.

I'll give it a go and let you know how i get on with it all.

I have one file within the minidump file.

Its from the 29th of april, but i've had the problem as recently as yesterday night with no more dumps recorded. I did have some initial problems with windows which i believe i have now rectified using updates/repair from install disk and SFC /scannow.

I'll attach my 1 file.

Ok,

So i've just played skyrim again and its just shut off, again. I had disabled automatic boot up but there was no bluescreen.

I'll be honest i haven't had a crash concerning the chip or its setting since that one crash, which if i remember correctly did produce a bluescreen.

@TVeblen i tested the power supply in 2 other rigs, one running a xeon and it seemed to work fine under stresses. It could actually be that the power supply is faulty, what i don't understand is that i can run intel burn and mem test for 10 hours but can't run skyrim for 15 mins?

The system was factory overclocked from the store i bought it from, and they test it for 24 hours to check for stability. It has been fine up until running those games. The computer doesn't suffer from this in any other program. it never does it surfing the internet, benchmarking/stress testing, on skype or anything else but certain games.

I guess as i have insurance that covers the build and faulty/defective componants for 28 days after the build i can use that to get fresh parts. Its just i use the computer everyday for work and play (in my downtime)
