Had ArmA a while, all patched up and game runs fine. The only problem I have is occasional crashes where my entire system locks up to the point of having to hold down the power button to power off. Over time I have realised that these lock ups only occur when I am in a helo. Doesn't matter if I am pilot or not. I've had crashes in SP missions, official and user made, Evolution when I've been a passenger. Crashes have happened with both BI content and also with RHS's superb Hind but ALWAYS where a helo is involved. I can play for hours infantry missions etc.
Anyone else had this problem? Any suggestions appreciated as it is now getting somewhat annoying.
