Hello Gugarion and thank you for the report.
Have you tried removing the contents of your C:\Users\*username*\Documents\DayZ folder to see if it has any effect on the issue? Have you tried to re-install the whole game? And are any files being created in the C:\Users\*username*\AppData\Local\DayZ (this folder is hidden in windows by default and you will have to enable hidden files in windows to access this folder - the folder is different from the one in documents\dayz) when the game crashes?
Regards,
Geez
