My Battlefield 3 on PC only seems to crash (BF3.exe isnt responding, etc) when I am flying in a Jet during combat. I have no idea why this is....

I currently have 6970 x 2 in Crossfire, stable OS: Windows 7 x64, 12GB RAM, i7 @ 3.8ghz with a 1200watt psu.

I have tried both the newest drivers for my video cards and the beta drivers: both do not fix this. My battlefield is up to date and so is my OS. I have tried reinstalling the game, to no avail. I am able to watch my temperatures of my CPU, GPU, etc on my left monitor while playing and everything seems okay.

It only crashes when I am flying a jet: Majority of the time on Kharg Island.

Any ideas / input?

EDIT: I read on some other forums that DICE isn't too friendly with pre Overclocked video cards. So I also tried down clocking ( QQ ) both of my cards and I still get random BF3 crashes. Only in the jet.

Does it crash everytime you're flying or only sometimes? Does it freeze up the PC up totally or does BF itself just crash to desktop? –  Emerica. Jan 23 '12 at 21:10
    
Only sometimes: Completely random from what I have noticed. Only BF freezes, I have to alt+tab then Ctrl + Shift + Esc to quit BF ( only way to regain focus of desktop) –  Zero Stack Jan 23 '12 at 21:13

It would appear you are in good company - battlelog.battlefield.com/bf3/forum/threadview/… –  Emerica. Jan 23 '12 at 21:28
    
Well I'm glad that I'm not alone, thank you for your backtracking. Still hoping for any suggestions until some patch is released. :/ –  Zero Stack Jan 23 '12 at 21:31
    
Perhaps I will give a bounty if I don't receive much input.. but I don't think it would even matter if it is a common issue. But then again: That sparks the question: Why are some people experiencing this problem and others not? –  Zero Stack Jan 23 '12 at 22:01

This is basically "how do I determine if my hardware is stable?"

Sounds like you've already tried

  • making sure your video drivers are 100% up to date

  • monitoring temperatures (though you should try the "open case with house fan blowing on it" to make absolutely sure)

But you have not tried

  • removing ALL overclocks: CPU and GPU. Make everything run at absolute stock speeds to reduce variables.

  • disable CrossFire in the drivers so you are only running on one video card, not two: does it still happen? (no need to physically remove the 2nd card, disabling CrossFire in the drivers should work)

The standard "is my system stable?" tests should be run:

  • run Prime95 overnight and see if your CPU is stable

  • run Memtest86 overnight and see if your memory is stable

  • run Furmark for an hour or so (be careful as this thing loads GPUs far beyond any realistic load)

Warning: Battlefield 3 is known to be extremely GPU intensive and may cause more heat than most games.

I have been running benchmarks and other tests since this post and I haven't seen any complications or indication(s) of fault(s). Thank you for your input, but I am not the only person with this issue as linked above from @Emerica –  Zero Stack Feb 1 '12 at 6:40
    
did you remove ALL overclocks? did you disable CrossFire? etc. –  Jeff Atwood Feb 1 '12 at 6:43
    
From all the testing I have done, it just seems to be a heat issue. I had to remove the side panel of my tower, and crank up my fan speed manually through the CCC. For some reason the CCC is off by 5 degrees and is not aggressive enough for automatic fan control. Thanks for your input and testing. I got these results from the one test I have never heard of: Furmark. –  Zero Stack Feb 6 '12 at 19:06
