What kind of error message do you receive and upload .RPT logs + dump files from %localappdata%\DayZ\ by placing them in a compressed archive and dragging and dropping it here to upload.

If there are no dump files in that folder, does Windows log an event in the Windows Event Viewer?
Ctrl+R "eventvwr" OK, check Windows Logs > Application
