Pc shutting down under stress, unknown reason.

Hey tech people!

So for the past 7 months i've had a pc that shuts down randomly when i'm playing any harder to run games (Ark survival evolved, PUBG).
Its a complete shutdown, no restart. As if i flip the switch. 
The issues started back in december when i switched my Motherboard/MEM/CPU. 
During a attempt to try and fix this with people on this forum back then we "found" the issue to be the PSU, which i replaced and upgraded.
Unfortunately this didnt fix the issue, the pc is still crashing. 

I have updated all drivers and the bios. 
The replaced parts are sent back to the seller to test for any issues, but none were found. These were the Motherboard/mem/cpu.
The current psu is 850w Gold so shouldnt have any issues suplying enough power.

If you need anything more to help out, let me know! 
at this point i really don't know what to do anymore..

My specs are :

Motherboard: Asus viii ranger
Memory: Corsair vengeance 3200 2x 8gb
CPU: Intel i7 6700k
GPU: Evga gtx 970
PSU:corsair Rm850x 
CPU cooler: cooler master hyper 212 evo

HDD: 2x Samsung hd204ui
SSD: 1x Crucial Bx200 480gb (current start up disk)

Case: NZXT noctis 450

When i crash it shows an error that the pc suddenly shut down 30 minutes earlier, i've added two screenshots to show what i mean.

More about shutting stress unknown reason
  1. Have you checked the temps of the cpu or graphics card while gaming or stress testing?
    Did you update your bios, there are new updates...? But do remember to update bios in an orderly fashion like if there are bios version 1,2,3 available and your bios version is 1 , then download 2 , flash it and then download 3 and flash it. And always remember to flash using bios and not not windows...

  2. Do try running prime95 for 5 or 10 mins and also check the temps while at it... Check to see if it crashes... If the temps rise above an alarming level stop the test immediately and post back the temps...

  3. When i bought the motherboard there was only one update available, and back then i watched a full tutorial on how to do/not do it so i assume i've done it correctly. Currently there is one more update that i haven't done yet as i've only just now seen there was a new one.
    And earlier today i've used the stress test from ASUS and this was the "result".

    The temps are very good... But do try running prime95 for 10 mins and see if it crashes or not...

  5. And also do post the error log details; in the pic i only see the general tab,

  6. Even if your PSU has enough power does not mean it is not faulty...

    Post the full error log please :)

    First do monitor your temps since you have not listed what you are using as a cooler for the cpu. Make sure it does not overheat. ( Even if I dont think this is the problem but has to be sure )


    What you can try and do is to take out everything you dont need in the computer.
    Just leave 1 stick of ram, Unplugg the 2 HDD`s, remove the GPU and run on the cpu`s graphics.
    Fans you should not need to pull out now.
    Now boot up with just the parts you MUST have and run games or what ever that caused your system to turn off in the first place.
    If it now turns out to be stable, add in 1 part like the 2nd RAM module and try and make the system turn off again, keep doing this with 1 part at the time until the system turns off by itself and let us know what parts has been put back in and what the last part was when the system turned off.

  7. i've let it run 5 minutes because i'm quite scared of letting it run further.
    It nearly instantly hit 97, going up to 99.

    (i did the heat test obviously)

    Ok, there you go, the issue is overheating... Get a custom cooler and your issue will be solved... :) In the previous post, i thought the temps were during load, but now i know it was in idle mode... Get a AIO cooler for your cpu... corsair h100 would be a good choice or good custom air coolers would do...

  9. The processor never came with a cooler so it already has a seperate cooler, the cooler master hyper 212 evo.
    Any recommended fans for the processor?
    Reply to CoolguyCain
  10. The processor actually cooled down real fast in idle, its on 21 degrees right now.

    Check to see if the cooler is properly seated on the processor, dont force it though... get yourself new thermal paste like the cooler master mastergel maker nano or the MX4. I personally prefer and recommend using the cooler master mastergel maker nano. The fans i recommend are noctua NF-F12 and corsair ml120 fans

  12. How can i see if its properly seated? (just making sure i check for the correct things)

    The idle temps may be little high but look at it the under heavy load temps, it shouldn't cross max safe temps...
    Idle temps depend a lot on ambient temperature...

    Best way is to take it out, clean the thermal paste on the cpu and heatsink using 90% isopropyl alcohol and toilet paper or coffee filters. Apply new thermalpaste; not too much, just sufficient amount. Reinstall the cpu cooler again and Check if it fixes things...

  15. Good thing sending the part back they put a tube of cooling paste with every single part (i now have 5 small tubes) So i can try it many times over!
    Thanks for the help everyone, since its 00:26 for me i'll be replacing the paste tomorrow as soon as i can. After that i'll do the prime95 test again to see if it worked and post the results.

    Many thanks!

  16. I am 99% sure that the 212evo is not seated correct. Starting to wonder if there is any thermal paste at all under there on top of it.

    I wouldn't advice you use that thermal paste, you should consider buying some new thermal paste likes the ones mentioned by me. I have seen stores use pretty cheap thermal pastes unless they are providing branded ones. The thermal pastes doesn't cost that much, and one tube will last you years... Thermal pastes really matters and i have seen temps fall down 20 C by using good thermal pastes. Anyways, its your choice.
    Also do try to check whether the cpu cooler fans are working properly on heavy load or not. For the fans i would advice you the noctua nf-f12 or the corsair ML120

  18. I've re-applied paste as i said i would, the paste is the stock coolermaster paste that came with the hyper 212 evo. (according to google its not a bad paste).
    Unfortunately prime95 test didnt give any new results, it instantly hits 90 and goes up to 99. After stopping the cpu nearly instantly cools down to 50.

    However, googling around i found that a lot of people have these temps using the newest version of prime95 on the kind of cpu that i have and have been recommended using version 26.6 instead of 28.
    After installing that version and running the test my cpu doesnt get hotter than 80 degrees.

    Yeah, I knew that but still its pretty hot using the previous version of prime95. The version after 26.6 uses AVX2 stress testing which gives unnatural temps, but 99 C and above is just out of the question on i7-6700k... and 80C is also very high considering you have a good cpu cooler...
    To me, the problem is overheating... do try to check whether the fans are working properly or not and if the fans are installed properly on the cpu cooler in the right direction...
    I would advice you to avoid running stressful games like battlefield 1 and other cpu extensive applications on such setup as it may literally fry up the processor and affect the motherboard...
    Hope other members on the forum advice you on the situation and you find a fix soon...

  20. a friend of mine just mentioned that the hyper 212 evo is not good for the 6700K, this is what he said.

    the evo 212 is good for i3's and i5's (Non k) since it is lower then 90 WATT TDP
    since coolers are made for x TDP max to desapate heat
    Even tho the evo 212 is rated for upto 180 Watt this cooler version is very old and coolers have been developed further which means even tho it only does under 180 watt it will be more effiecent in cooling your CPU.

    i'll be honest and say that i don't really follow him here. but any thoughts on it?
    Reply to CoolguyCain
  21. i've checked and checked again and the fans are all working properly.
    i have also moved one front fan to the top in the case right above the cpu in the hopes it'd work (its blowing outward)
    Reply to CoolguyCain
  22. Ok, so... Hmmm.... I am literally thinking about the issue since yesterday...
    ok, do you have any other intel stock coolers in your house, any will do since the 2nd generation of intel cpu's, do reply because its late night here and i want to solve your issue tonight itself...
    Reply to Sohom
  23. Ok, so i have asked some experienced people here to help with the problem. Hope the issue gets resolved soon.

  24. i unfortunately switched from AMD to intel for this run so i unfortunately don't as this is my second pc.
    Reply to CoolguyCain
  25. Hmmm, okay no issues there.. can you post a pic elaborating the fan setup in your case...
    Reply to Sohom
  26. best i could do was find a stock photo and draw the fans with arrows.
    https://gyazo.com/a34076ea9d7bea5da128b3ed7b0b446b
    Ofcourse i would have a hyper 212 evo

    Ok, so the fan setup is just fine... If you have one fan on the top, i would ask you to move it to the top back rather than the top middle, though it doesnt matter in solving the current scenario...
    My last conclusion seems you need a better cooler, look at a few noctua air coolers or some budget AIO coolers, even try new thermal paste or new fans; I am literally out of clues... :)
    Reply to Sohom
  28. The thing is that even if the Hyper Evo is not strong enough for the 6700k, i highly disregard the fact that temps can go above 100C causing the system to shut down. The 6700 uses stock cooler, so why a better optimized cpu cooler wont work...
    Reply to Sohom
  29. thats exactly what i was thinking, but my temp is 70-80 on 40% load. which is WAY too high but i don't understand how its possible.
    Reply to CoolguyCain
  30. See if you can get a watercooling AIO solution on a budget... My last advice would be go with it... You can try the corsair hydro series, deepcool 120 ex captain or better the 240... TomsHardware has already a list of the best Air coolers out there, see if you can get one within budget...
    Reply to Sohom
  31. i guess that will be the way it'll have to go.
    I thank you a lot for your time and help!
    Would you like me to give you an update after i put in a watercooling system?

  33. it will probably take me over a month to be able to buy the cooling system, but i'll make an update when i do!
    Reply to CoolguyCain
  34. 2 things you can try atleast:

    1. Do you have a good and big table fan or a big floor standing fan in the house?
    If you do, can you take of the side door on the case and place the fan close and turn it up to high so you move an insane amount of air if you compare it to your case fans. Place it close and aim it straight at the CPU cooler alittle on the side. What happens to your temps now? If it still fails look at nr. 2

    2. Go into bios and turn of hyperthreading and turn of 2 cores so you are running just a dual core without hyperthreading.
    If you now still have heat problems something else is really really wrong.

    This is just to be 110% sure it is your cpu cooler even if I am atm 99% sure it is.
    Reply to lumineZ
  35. okay so putting a fan on it still crashed it but it took longer, disabling hyperthread actually hasn't crashed me yet.
    Using prime95 v28 (the one that gave me 90 to 99 degrees earlier) i now get an instant 85 which rises to 88.
    Reply to CoolguyCain
  36. Well atelast you found an answer with it. It it something with either the cooler or the thermal paste. Ofc it could be a mix of them both.
    If I where you now atm, I would stop running prime on it until you can figure out what is wrong with the cooling setup you have now or get a new better cooler.

    Dont turn on hyperthreading either until you get this fixed, no need to "cook" the cpu.


    Your cpu is more than good enough to play games etc still "just" as a quad core without the hyperthreading turned on. Just let it be until you get it fixed... Even if I have to say... something is not right with the 212evo since it should be able to handle the heat with a 6700k at stock settings.


    Sidenote: what a....... just did read through the whole post again... And cant help to wonder why no one has asked my self included............. sooooo here is the question... : What is your Vcore idle and under load.... jezzz.... hehehe talk about a brainfart to forget to ask about that one... :D
    Reply to lumineZ
  37. Ok here's a question. If you leave that side of the case open like you have it in the pic, and run the computer like that, do you still have high temps?
    Reply to Sedivy
  38. luminez, how do i find the vcore? and do you want to know with hyperthread enabled or disabled?

    Also is it possible my motherboard auto-overclocks the CPU?
    Reply to CoolguyCain
  39. Get something like HWMonitor and look at the output. It'll give you voltages, temps, clocks, everything.
    Reply to Sedivy
  40. Okay so, i just crashed with hyperthread disabled ( didnt have the big table fan blowing)
    Reply to CoolguyCain
  41. BTW, I may have missed it (there's so much to read in this thread), but have you used the Intel Processor Diagnostic Tool to test the health of the CPU? See...
    https://downloadcenter.intel.com/download/19792/Intel-Processor-Diagnostic-Tool
    Reply to ArtPog
  42. Go here and download / install this program: http://www.cpuid.com/softwares/hwmonitor.html

    Open it look at voltages on top, there you see one called Vcore.
    what is your value, min and max?

    It does not matter if you have hyperthreading enabled or not when looking at Vcore at the moment.

    Auto OC? Depends if you have boost enabled (default on the motherboard that is on) but that should not matter since the 6700k is supposed to do that.


    I just want to know Vcore and what RPM your cpu fan is running at ( also listed in HWMonitor )

    Should be able to solve this with just alittle more info :)

  43. This is hwmonitor in when i only have my startup programs + chrome open. https://gyazo.com/d574e6f236ee85ddf112e5382e0e03c3
    Reply to CoolguyCain
  44. I...well granted I have a totally different cpu but isn't that cpu vcore a little high for idle?
    Are you overclocking?
    Reply to Sedivy
  45. i've just ran intel health test, and it passed all the tests.
    Reply to CoolguyCain
  46. i didnt overclock as far as i know. The only way i can think of is the mobo auto overclocking it,.
    Reply to CoolguyCain
  47. Can you post a bigger screenshot, one that includes core clocks and utilization? The clocks will fluctuate constantly, that's normal. Watch them for like 10sec and then just include if they're constantly staying at one (high value) or hopping up/down between particular values.
    Reply to Sedivy
  48. It seems to be overclocked https://gyazo.com/4db2aa46e3e9cad0389c7ed53676cbfc
    But according to lumineZ that shouldnt matter.

    the utilization :
    cpu 0,2,4 change around 3 percent.
    cpu 6 changes around 6% each jump

    This screenshot was made directly after startup again.
    Reply to CoolguyCain
  49. No, there's your issue. Your clocks both min and max value are stuck as max and not budging. This is not how it's supposed to be. Default idle clocks are around 800MHz and that's where they should be individually when on idle though they'll hop occasionally to higher values, they'll come right back down. But this isn't happening with yours. It's like your cpu is constantly stuck on currently OC gaming mode and it's likely why you're having higher temps on idle.
    First go into windows power management and check what it's currently set to. Set it on Balanced if it's currently set on Performance. Also go to advanced link at the bottom and check the power management for the cpu specifically.
    Should be Settings->System->Related Settings->Additional Power Settings->check which is preferred plan. If on balanced, click on change plan settings->Change advanced power settings->processor power management. Check what's minimum processor state.
