I am having the problem that DayZ is closing randomly while I'm playing the Game. I am not getting any error messages or anything like that, it simply stops and sends me back to my desktop. I have been playing for about a week now and this issue has occurred at least 30 times so far. Sometimes I can play for only one minute before the game crashes, sometimes it happens after an hour or more.
So far it has happened in various situations such as simply running around, however I have noticed it happen multiple times already the exact moment when I hit a zombie with a melee weapon.
I have played with several characters by now on both public and private servers, I have tried different graphic settings and playing in windowed mode, I have installed the latest graphics driver and also tried an older one as well as checked my system's temperatures. Every time I was experiencing this problem though.
