Prime 95 fo my new build

hey guys i built a new PC yesterday. i was playing far cry 4 and suddenly it stopped playing. the computer was not turning on even after pressing the power button. after 1-2 minutes it spawned back to life.
i think it got overheated?
i ran prime 95 test and here are the results.
my CPU is i3 4150
GPU zotac GTX 750ti 2GB ram.
PSU corsair CX 430
i am using cooler master evo T3
8GB corsair ram

please tell me why my PC shut down.

  1. your max temp looks too high--though prime95 puts more stress on than real life gaming

    check your heatsink is properly installed especially if its a push pin one

    and you did use thermal paste?
  2. The temp at max load is a little bit toasty but not enough to cause a system shutdown. If i recall correct the system shuts off at 100C and throttles (decrease clock) at 90C. Also Prime95 causes voltage and temps to be higher than any real world scenario.

    Make sure that the power cord from the wall to PSU is in FIRMLY. Make sure (while the computer is off, of course) that all connectors in the motherboard from the PSU are connected properly. Try also re-seating your memory.

    If you still have issues, run MemTest to check your RAM for errors
  3. i didnot see any stutters before shutdown. the fps were around 55-60 and then bang the pc turned off. i had to remove the power cord and insert again to start the PC. yes, i applied thermal paste just a rice grain size. should i clean the cpu and install the cooler again?
  4. rice sized is fine--if its a push pin cooler make sure all pins are properly engaged
  5. one game crash could be caused by anything though doesnt have to mean overheating
  6. yes the pins are properly inserted. the thing that is concerning is that i was not able to start the PC after the crash. i removed the cord and had to reinsert for the pc to work.
  7. yeah its not that unusual to have to remove power cord press on/off button couple off times then plug power back in to restart

    i have had it quite a few times particularly with asus boards for some reason
  8. so what do you guys say. should i remove the cooler and reinstall it? or are those temperatures fine for prime 95?
  9. so what do you guys say. should i remove the cooler and reinstall it? or are those temperatures fine for prime 95?
  10. if prime95 didnt crash/overheat it then it just might have been a random error

    try your game again see if it happens again--or can redo the cooler if you want but your game wouldnt have got it as hot as prime95

    how long were you playing the game? ie did it do it right away
  11. no i had been playing for about an hour
  12. i would just play the game again if it doesnt do it again it was a one off
  13. but ias in the OP i displayed the prime 95 temperatures. are they fine for running it 10 min. it was a small ffp
  14. if using the default cooler they are ok for10 minutes of prime95 will get it heated far beyond what real life use will
  15. i am not using the default cooler. those temperatures were with cooler master evo t3

    I have a system with an i3-4150 and the stock cooler. It runs Prime95 28.5 Small FFTs for hours without issues, i.e., it never goes over 90°C. Yours runs cooler with the TX3 EVO; your issue is elsewhere. If I were you I'd test with a different PSU (even though a CX430 is plenty for that system).
  17. so are my temperatures high for a cooler?

    They're fine, particularly if you run Prime95 28.5 (you didn't specify which version). If unsure, then why not check the CPU with Intel XTU while running Prime95? Don't bother with XTU's CPU stress test as it doesn't stress it at all. The fan won't even need to run faster to keep it cool.
  19. yup its the 28.5 version
  20. I agree with all replies from mcnumpty23; as he suggested, try the game again and if it fails, then I'd suspect the PSU or the GPU before other components.

    :) thanks was beginning to think i was talking to myself
  22. i am out for few days. i will return tomorrow or day after. once i get home i will try to play the game again for few hours. if crashes then i will clean the CPU. will keep you posted here. thanks mcnumpty
  23. ok i played far cry 4 for almost 2 hours. the PC didnot crash. the temperatures remained at maximun 63 degree celcius. well ambient could be around 27-30 degree Celsius. so guys everything good? do i need to apply the thermal paste?

    63°C is fine for that CPU.
