Computer totaly freezes after some time in ArmA

[exl 0]

Hey guys! I recently bought ArmA 2 for just this mod and i'm having problems. after i join a game or start a singleplayer game it holds on for sometime and the it just freezes. I can hear the sounds but it doesn't respond to any commands, not even CTRL+ALT+DEL or ALT+TAB. So i end up restarting my computer. This is annoying as hell, how can i fix this?

Your computer is locking up and crashing

Whats your computer specs?

Yeah We cant really give an 100% sure answer without your specs but its probally a problem with the hardware. Arma is very heavy on your cpu and gpu and I am guessing that Arma is taking too much proccesor usage wich may result in vital programs not working propperly and locking your pc up.

Maybe no good to you, but an old ATI video cache flushing method is to

press: "shift - flush"

Try updating all your drivers for motherboard chipset, direct x & graphics card drivers.
