DayZ Green Blinking Glitch HELP

Everytime i run dayz or arma 2 oa in general, the game screen blinks green, like its a resolution problem or something, anyone know what to do or have any suggestions.

I have never had this or heard of it, try reinstalling, updating directx, updating graphics card drivers. If that doesnt solve it, your graphics card is done :P. Get a new one
