Please Help! Arma 2 stopped working

[ndgaming89 0]

Can someone please help, i got:

arma 2 - combined ops (from steam)

Ran them both (played and enjoyed :))

Got the day z mod (1.8.1) from Dayz Commander (But i also got from steam, (I think))

got the epoch 1.0.4.2 aswell 

and got arma 103718

 

i can jump into servers fine but suddenly after i have been for playing for anything from 5mins - 2 hours i just get a screen appear saying Arma 2 OA has stopped working?

 

i have tried to validate my steam files, deleted everything and started again, is this a problem with the game or a problem with my drivers or something maybe, i just dont know, but im just waiting for the moment where this actually gets me killed when i have a lot of gear.

 

My specs 

Acer Aspire 5750

Intel Core i3 - 2310m

Intel HD Graphics 3000, up to 1760 MB Dynamic Video Memory

15.6'' HD LED LCD

8 GB DDR3 Memory

750 GB HDD

NVidea GT 630m 

 

Anyways hope this makes sense, thanks in advance and please help :(

Your problem might be that you're playing on what appears to be a Laptop. Did you make sure it's not overheating?
