Hello itheonlyking.
Are there any errors appearing? If so, please click on the "Show and prepare report log" and upload the generated archive to this ticket.
If the game crashes without any errors, then please try the following:

Verify the game data through Steam and delete the configuration files when prompted to do so (make sure Steam cloud sync is disabled for DayZ before doing this) - you can also delete the config files manually by clearing the C:\Users\*username*\Documents\DayZ folder

Open the DayZ launcher
Select PARAMETERS menu
Select ALL PARAMETERS tab
scroll down and check "Bulldozer" parameter
Launch the game
Once launched, close the game
Uncheck bulldozer
Launch the game again without any parameters

Regards,
Geez
