Black Screen - after the game has been playing well

[ReddDraggon 10]

C2D E6400 @ 2.6GHz

8800GTS 320mb (OC'd)

4GB mem

Vista 64bit

I'm happily playing away for 5 or so mins, and then the screen goes black. If I press escape I get the "ArmA2 mouse pointer" up, and I'm not getting any error messages. I can still hear the music/soundeffects playing in the background.

I have the most up-to-date Nvidia drivers installed too.

I had a search on the forums and none of the problems seemed to match my issues.

Thanks in advance.
