Computer crashes when gaming

First off, my specs

CPU: Amd fx-8150
RAM: 32gb quad channel ddr3
GPUs: Crossfire: ATI Radeon HD 7870 series X2
OS: windows 7 pro 64bit

This has been happening for as long as I can remember. Whenever I play a game (Tested with Counter Strike: Source, Assassins Creed II, and Black Ops II) after 10-20 minutes, the screen loses signal, and I can still hear the game going on for a few seconds after, but then the sound starts to loop, and I can't get rid of it until I hard restart.

I am pretty sure its not the CPU or GPU overheating, as the gpus' temperature stays between 50-70c during gaming, and the cpu is water cooled and stays around 50c.

  1. I had kinda a similar problem and it plaqued me for 2 months. Drove me nuts.

    I ended up fixing it by reseating the CPU.

    Someone recommended it and I dismissed their suggestion. However when I did it I found the CPU got wedged in the socket. It was very difficult to the the arm bar to release. However once I did and reseated the CPU with new thermal paste everything worked fine where as before it would consisently fail just minutes into games.

    Looking back on it I was messing with my PC one day and I think I accidently bumped the Heatsink too hard with my hand. As a result it placed too much pressure on the CPU's memory controller and started causing memory errors when manifested themselves in my games dying at random points.

    Not sure if this is your problem but I hope it helps.
  2. One other thing also.. Have you tried removing one of your 7870's and cutting your memory from 32 GB back to 16GB? If not I would highly recommend doing both just to see if it makes a difference.
  3. I have been playing CS for about 20 min now and it seems fine without changes, ill report back later on how it goes.
  4. Ok, it crashed at around 11:40pm. Is there a way to make sure that either is the problem before I go about unhooking my watercooling and pulling things out?
  5. 4 possible options: (none of which worked for me however they may work for you)

    1.) You can try downloading the Belarc Advisor - a free system diagnostics, system information and benchmarking to create a problem report.

    2.) You can also run a Dxdiag report.
    a. Click on "START"
    b. Click "run"
    c. Type in "dxdiag" and click "OK"
    d. Check through the tabs and perform all tests
    e. Click "Save all Information..." and save the text file to a location of your choice

    3.) Run SFC Scannow to check the intergrity of your system files:

    4.) Check for memory problems:

    I am not sure how elaborate of a system that you have set up but I know it is a pain to work on. However it is the weekend so if you got time you might want to try it. If nothing else it will give you an opportunity to clean out your case.

    Best of luck to you which ever path you choose.

    Other Thoughts:
    Should you attempt to remove the water block you may want to put it back on with a little less pressure at first just to test.

    When I had this problem I was not able to go more than 4 hours with out a crash and that was a rarity. Most often I would not last more than 5 minutes gaming. Youtube would crash streaming video also however that was less common.
  6. Thanks, ill try them now!
  7. It did not work. I have the thermal grease and remover on order to arrive tomorrow. Ill tell you how it goes!
  8. My computer lasts a lot longer than 5 minutes, it lasts around 40. Im not sure I have the same solution.
