  1. Looks like it could be the video card failing. I recommend you contact BFG to discuss possible RMA. You might want to also try a different application to see if it happen only in that game or all. Also try using Ntune and under clock the video card 5-10MHz at a time and see if that helps. If so then you can almost certainly bet its the video card.

  2. these are the settings
    gpu clock settings
    CORE BUS 400MHZ
    MEMORY BUS 625MHZ

    do i decrease the core bus by 20? sorry not really good at this stuff >.<
  3. looks like it could be ovrheating to me use Ntune or Riva tuner or both and check the temps

    Though getting a new card will fix the problem anyway.
  4. you might check the temps as said before.

    have you checked to make sure the fans are spining
    and that everything is free of dust?

    nevermind: if it is at 43c the temp is fine.
    may be your card like said before.
  5. yeh the fan is still spinning..it sometimes spins loud. and then quietly is that normal? when i restart my computer and play any game it works fine then after like 30mins later it starts to glitch... still not sure what is wrong, i only had that graphic card for like 4 weeks only.. on just got it.. >.< isit to do with my motherbaord maybe? or mayb it needs some fans blowing inside my pc? >.<
