Have had crashes before but last month or so just constant random crashes. Game will run about 15 mintues usually (sometimes longer) - then game will just randomly freeze, hang on frozen screen for a few seconds then crasht to desktop or will crash to desktop with a dialog box "DayZ has stopped working".

There seems to be no regualr element of game play that brings on a crash - can happen in a buidling, can happen while in a field.....often happens when running but most of the game is spent running so don't know if that means anything.
