FA crash/freezing, only resumes when going back to desktop

[PeteSapai]

My game crashes (or actually freezes) way too often (almost every other game) at a seemingly random point in game.

Playing on 2x24" monitors. Win7 x64. Radeon 6780 on driver 13.1 - newer drivers give me the mouse lag bug (moving the mouse on pri monitor makes the game stutter) so I can't update my drivers

It runs fine the entire game until at some point everything turns black at which point (when I host the game) the game freezes for the other people. If I return to desktop, their game resumes (and my forgedalliance.exe's cpu usage drops to 0). If I switch back to the game, my left (secondary) monitor flickers black/grey and the right (primary) monitor is black. The game also freezes again for the other people until I return to desktop again. At no point do I hear any sounds again.
It also happens if I'm the only one playing or if I join someone else's game (though if I'm not the host, my freezing doesn't affect the other's game).

This game ("The Nomads", but note that it also happens in other game modes) started on 2013-11-24 around 17:30, I paused it at ~18:20 for dinner, resumed around 20:00 and then froze at about 20:28.

Here's a 2nd game crash. Small difference: my 2nd screen goes completely black too, in stead of flickering.

"DeviceD3D9.cpp(937) Invalid call"
I read in another thread that it's a AMD card problem and that switching to windowed will fix it (though that's not a very good solution).

I have the exact same problem and I also have AMD and two monitors. Any solutions?

Haven't played much since I posted this problem. All I can say is that I played 3 or 4 games Windowed (stretch it over your 2 monitors and press F10, I think, to split the screen) and the game didn't crash. Far from optimal, but better than a crash once every 2 or 3 games.

I also have this problem, it started like one week ago, i didnt change anything on my computer. I only use this computer for supreme commander so there is nothing except Win7, FA, FAF and some required programs. The game freezes with glitched graphics, after some time i have to kill the process in the task manager.
The only thing i did change is that i attached another monitor to my pc. Maybe its caused by the 2nd monitor, i will it out without the 2nd monitor attached now.

Here are the logs. I couldnt find the faforever.log file descirbed in the faq thread.

Thanks in advance!
