I am having a problem with arma 2 cause every few minutes I am getting screen blocking itself and it doesnt matter is it in the time of playing or while i am in the menu. The screen and everything just freeze for few seconds or longer, than runs and than freeze again (sometimes it is happening for long perioda of time). I defragged but it didnt help i have the freshest graphic drivers as well. I am sorry for my english and please try to help me cause I am not computer expert.
My computer is :
Nvidia gtx 280
e8400
4 gb ram
