I have been having this problem since Windows 8 and it has now persisted through Windows 10. I can launch my game and enter servers but after trying many troubleshooting processes I continue to have the Windows 10 alert noise to let me know something has gone wrong and my game will freeze. I can't do anything so I have to either use Ctrl+Alt+Delete to end process or Ctrl+Alt+Delete and then spam my Esc key to close DayZ which then brings me back to steam and my desktop.
Specs of my PC are as follows:
CPU: Intel Core i5-3570K @3.40GHz
System Type: 64-Bit operating system, x64-based processor
GPU: GeForce GTX 760 on driver version 353.62
OS: Microsoft Windows 10 Home
