4 weeks ago I started playing DayZ. The first weeks everything was right, but then, 2 weeks after the beginning, when I would open the game and press play in the main screen of the game, the countdown of 15 seconds would start and then the black screen with a loading bar in red would open. However, only 20% of the times, the game would be loaded. Usually it gets there and if you change the window to other out of the game, the game crashes and it is impossible to finish it (not with the tasks manager, not with the shell). So I need to restart the computer every time the game crashes.

I have tried to verify the files in steam, redownload the game, remove the previous files of DayZ in the folder Documents and even I tried formatting the PC. I also tried to check for previous Windows updates but there was not an update recently. None of this would be succesful.

Sometimes it gives some error according to BattleEye, but very rarely.
