Bought dayz standalone everythings fine, 400+ hours and everything working like it should. Until one day I start up dayz. A black screen flashes dayz opens up but nothing changed except I cant see my mouse cursor anymore. Looking at everything on my screen as if I were alt tabbed out of dayz. I can hear the sounds of the coast when its running just nothings happening. I have uninstalled dayz, Didnt work. And I even uninstalled steam and re installed dayz. That also did not work, Any suggestions please?
