Prime95 Tests - PC crashes instantly.

Hello Everyone,

I've just tried to run a Prime95 test to find out why my PC crashes when playing certain games. When I run any of the three tests suggested my PC crashes instantly.

My PC:

Motherboard - ASUS Sabertooth 990FX
CPU - AMD FX8350 Black Edition 8 Core Processor
RAM - Corsair Vengeance 16GB (2x8GB)
GPU - ASUS Radeon HD 7870 DirectCU II 2 GB
PSU - Corsair HX850 850w Gold Power Supply
Case - CoolerMaster Enforcer

If anyone could give me any guidance on this subject it would be greatly appreciated.

Thanks!

  1. Are you overclocked? Is this a new build? Has it always done this?

    I am not overclocked. This is not a new build. I built this about April 2013. It has only just recently started crashing during certain games, and Youtube. I have reinstalled WIndows, and updated all the drivers etc. I tried running a Memtest86 and got to 16% on Test 13 - Hammering Rows, where it would just sit and not move. I then resorted to running a Prime95 where it has just crashed as soon as I press start on the test.
  3. Hello,
    Have you overclocked your machine? Try memtest to see is it your RAM.
  4. Which prime95 stress test are you doing it will give you the option when you start the program there is large fft, small fft, and blend. Choose the small fft option and see if it crashes.

    I've tried all three with the same result.
  7. If this is not a Overclock. (Which has been asked twice now...) then do that anes said. Do a ram test. If that shows as fine then one thing I can say is to increase the voltage of the cpu. not by much. Just ONE increment.
  8. If this just randomly started happening i would assume a ram stick or the cpu is failing.
  9. My system is NOT overclocked.

    I have done a RAM Test - memtest86 - and it got to 16% on Test 13 - Hammering Rows, where it would just sit and not move. There were no errors thus far, but I couldn't make it through one pass with 11 hours on the clock.

    I will try the CPU voltage.
  10. May I add, I have tried the memtest86 with both sticks in, and individually, with the same results.

    I tried running the test in Parallel Mode (Multi-core CPU) rather than singular, and my system rebooted within 5 - 10 seconds of starting a memtest.

    Do you have another computer you could test the ram in?

    Not right now, but I can ask my friend if I can try his.

    I would do that to see if the memory is good. If it is then i would guess your cpu or possibly something weird on your mobo is failing.
