Reboot under load

I just replaced my Mb/CPU/Ram two days ago and have ran into an issue with the system rebooting while under load ( specifically while playing COD: BO).
I seems to do it randomly but always while playing this game..meaning sometimes when starting the game up for the first time or after an hour of playing. Everything else seems to run stable the rest of the time.

gigabyte p55
4g Corsair xms3
GTS 250

CPUID shows that the cpu is running at around 40c at idle, and I am running an earthwatts 500w psu.

I am at a loss so any input and help is appreciated.

  1. You are going to have to run a stress test (Prime95 or other) and see what your temps are when at full load for a long(er) period of time. On the surface it sounds like you are hitting some protection threshold. This assumes you didn't just slap your old hard drive on the new motherboard without reinstalling the OS... Check your temps, then ensure all drivers (motherboard) are up-to-date.
  2. Thanks for the reply. I just downloaded prime95 and will start that stress test now. I did use my old Hard drive's but it is a fresh install.
  3. Ok Prime95 ran for 35 minutes and completed 24 tests. The system never shut off, max core temp hit was 81c.

    I used Gigabytes download center and all drivers are up to date.

    Are you overclocked? Stock settings for CPU / Memory / GPU? Memory configured per the recommended timings and voltage? May want to run FurMark to stress test your graphic card.

    FYI - Let Prime95 run for at least an hour to ensure stability...
  5. No overclocking what so ever....I am not sure if you are asking if the cpu/gpu/memory is at stock settings or if you are asking what the settings are? But the hardware is the same as it came out of the box.

    I will try the FurMark and I can rerun prime95 for an hour.
  6. That happened to my new GTX 470 recently (same game too). I got a blue screen telling me there was some sort of driver issue and it restarted, maybe about 2 hours in. It was the only time its done that though.
  7. Sorry... I was asking if you went into the BIOS and manually set your config for CPU / Memory / etc, or if it is a "default" BIOS config. May be worth it to at least set the memory to the manufacturers recommended config.
  8. I downloaded Furmark and attempted to run it at 1280x1024, fullscreen, I selected the stability test and clicked go....

    The system shut off immediately and restarted, basically the same way it does with COD BO.
  9. What kind of power supply do you have? Flaky or inadequate power will create the same symptoms.
  10. It is an Antec Earthwatt's 500w. The PSU is about 2 years old.
