I have:
1) i5-3470
2) geforce gtx 650
3) 8GB Ram
All game settings are on minimum and the resolution of the game is 1280x720
While playing a game at random moments the game folds to half (I see part of the desktop). Sometimes instead of minimizing at random moments a black screen appears (I do not move, I can not hear the sounds, etc.). When a black screen appears or when the game is minimized, I can not do anything. I can not minimize the game completely or open the launcher. All I can do is open the task manager and close the process. I can't even see the task manager, it doesn't show up, I have to close the game at random using the keyboard. This happens even when I'm not on the server but just sitting in the main menu.
I've tried: 1) Start the game as an administrator 2) Change the swap file; 3) Change the resolution of the desktop; 4) Update all drivers and also try to download old driver for videocard; 5) Reinstall the game 6) Change compatibility of the game with Window Vista 7) Turn off the optimization full screen in the properties of the game
