I just built a new PC and a clean install of Windows 10 along with Steam and DayZ. I'm having the same issues as my other PC.
I have 355 hours of somewhat good gameplay in and shutdown the PC two nights ago just to have the game crash when I booted up the next night. There wasn't anything installed or changed since the night prior and the game just won't launch now. If I launch DayZ through Steam or with DASALauncher, the game will minimize and then go into full screen and lock up the entire PC. I'll need to hard shutdown the PC. I've uninstalled DayZ twice and checked all the drivers and it still happens. I then uninstalled Steam, reinstalled it and DayZ just for it to keep locking up the PC during launch. I figured that I would do a clean install of Windows 10 and see if that helped just to have the game sill not launch. I've searched hours and tried many things prior to the clean install and I don't know what else to do. I'm attaching the files needed to the ADDITIONAL INFORMATION section of this ticket.
