I have been playing DayZ for about a month now with no problems whatsoever, but tonight, i came on and decided to play around with a few of the video settings on the game (not sure whether this has affected the situation but it may be relevant nevertheless). I then restarted the game only to find that it wont load. When i say this i mean the game does actually load, but nothing shows, and then i get a message from my monitor appear on screen saying 'no video available', as if there is no signal from my computer. However, i can simply alt-tab from the game and the signal comes back again. Since i run the game from the beta patch shortcut i have tried updating the beta patch and have still had no luck. I can still run the game from steam but that is no use to me. I have also tried updating my driver software for my graphics card. Any suggestions as to what may be the problem would be very much appreciated. Thanks.
