@Vitaliy Prulis/ @Billy Kruger could you give us some basic information on the hardware you are using?
If you've already tried to:
Verify your game files via Steam
Re-install the game
You can also try to
delete the DayZ folder in your documents manually
go to C:\Program Files (x86)\Steam\steamapps and delete appmanifest_221100.acf - afterwards verify your game files
more advanced: go to C:\Program Files (x86)\Steam\userdata and make a backup of that folder (in case something goes wrong, you never know). Afterwards, you can dive in and delete data with the number 221100 in the name. Afterwards verify your game files and try again
If this still does not work, we recommend you to contact our feedback tracker at feedback.dayz.com with a private ticket. Please include your crash report and your DxDiag report.
