Every time you try to enter the game from Steam, the shortcut on the desktop and the executable file with administrator rights. I bought a new computer a couple of days ago, but the problem persists. Steam support says to contact you.

Cleared the game cache, cleared the download cache. The game stopped responding altogether. Nothing happens at startup. Reinstalled Steam and the game and again the black screen for 30 seconds, and then the desktop without errors. Other games run without problems. The only problem with DayZ
