[Arma 2 oa crash]

Well, i start up ARMA 2 OA, join an island life server, play for like 40 minutes and then it says: ARMA 2 OA is not responding. I don't know how this is, but i dropped my computer a tiny 3 cm 2 days ago, and that's when this problem started. I have had problems in the past where my motherboard was stuck in my computer case, and it wasn't in the right place, so i may think the same thing is going on.

Specs:

AMD RADEON HD 7850

INTEL CORE I5 3450

MSI H77MA-G43

I really want to play ARMA again, so please respond fast. :D

Thanks already,

Levi
