I only started having this problem when I started using Windows 7 Previously I was using a Windows 8 preview, and the game could run for hours on end. Now, is it is played for around half an hour, it will freeze, and act like I have tabbed out, but then I can't get back into the game, and it has to be closed via task manager. Anyone know what might be causing this? I have an Nvidia GeForce 550 Ti (1GB) GPU, and I have 8 GB of RAM, so I don't think the computer is being put under too much strain, as I also would have had this problem running on the other OS in that case anyway. I am also currently using the Free version of Arma 2, if that has any known effect.
