Issue described here: http://www.reddit.com/r/dayz/comments/2tojou/dayz_has_stopped_working_crash_help/
I newly installed the game, after a while of not playing. I started the game, accepted the BattleEye EULA, and then immediately saw a white screen with the error message "DayZ has stopped working... Windows is checking for a solution to the problem.", after a moment the error and white screen disappear as the game closes.
Each attempt to start the game since has the same error, but I no longer see the EULA prompt.
I have been able to run the game on this system before (about 9 months ago, when I last played).
