Computer restarts during gameplay


When I play world of warcraft, I recently started getting reboots during 2 minutes of game play. I ran a windbg memory dumb and came across this. What am I suppose to do next to fix the problem?

  1. My gut feeling is it's one of 3 things (in no particular order):

    1) A driver - have you updated your graphics driver since it started happening? If not, then probably not the issue.
    2) Temperature - blow out your PSU, graphics card fan, CPU fan and anything else that collects dust. Run it with your case open. Download Speedfan and see what your temperatures are
    3) Failing hardware, most likely RAM or PSU. Run Memtest86 to see if your RAM is ok.

    Do you play any other games or primarily just this one? The reason I ask is because I'm curious if it happens only with this specific game (others play fine). Do you do anything else that is graphically or memory intensive with this machine? I suppose if you do other things with it that should result in the same failure but doesn't then it could be something up with the game itself. Maybe there are patches for it, or maybe a patch was installed and now it's crashing...
  2. I'm going to give it 24 more hours before I label this solved.

    Because nvoclk64 was the problem, I figured it would be an nvidia issue. It turns out the problem was nTunes. It was causing a lot of problems and I remember installing it in April of 2011 and that's when my problem began. It's gotten worse until I removed everything there is about nTunes except the uninstall doesn't work and add and remove programs. The icon is still there and it says 30mb. When I try to uninstall nothing happens. I removed every registry that had nTunes and deleted the folder.

    Also, there's been issues with the new nVidia drivers 275.50 that causes the BSOD or black screen halt with a system reboot. I went back to 266.58 which seem to be the most stable drivers. I see nothing new with drivers besides fixes for 3D. People really use 3D that much?

    Hopefully it works but I'm not going to label this solved just yet. I also would like to mention I removed the HD AUDIO folder before installing my drivers. Audio has been known to cause this problem too.

    To the fix the audio problem with nVidia, go to device manager and under System devices DISABLE NOT UNINSTALL the High Definition Audio Controller. That itself will remove the HD AUDIO in sounds and video.

    I will keep you posted and hopefully this could be a fix for everyone that's been having this problem as of late.

    I tested with Microsoft Flight Simulator X. Everytime I was about to leave the gate the game would crash. I'm happy to say that I flew from Chicago to San Francisco and landed safely with no system restart. I hope the problem is solved. :)
  3. Nope, it happened it again. :(
