I have a problem with Dayz (Origins). After some time (sometimes 2 minutes, sometimes 2 hours) my game crashes. In most cases my screen just gets black and i hear a sound as if someone just restartet my computer and the screen power led keeps blinking as if the computer is not running anymore. In fact, the computer is running (at least the power led is on), but i have no chance to get my screen back. Sometimes i even have to restart my computer several times, to get my screen to work again, because after one single restart my screen just keeps blinking as if it gets no signal from the computer. In the other cases (probably 25% of the time) my game just freezes and i have no chance to close Arma2 OA or do anything. Tabbing out aswell as tast manager doest work. I have to restart my computer too. I didnt have this problem some days/weeks ago and i have the feeling, that its getting worse. Some days ago i could play probably some hours before the game crashes in one of the two ways above. Now, i cant even play for half an hour. I first thought, that my power supply may be damaged or my CPU/GPU overheats, but i ran both Fumark (100% GPU usage) and prime95 (100% CPU usage) for half an hour without any problems. No overheating, no power supply problems. I alsohave no problems with other games on max graphics (FC3, Diablo, ...) It is also misterious, that these crashes often occure, when i enter someone´s gear (e.g. looting some body) or vehicle´s gear, aswell as opening the map. Entering a vehicle gear from inside via "m" -> units -> gear crashed almost every time, especially in the black limousine vehicle.

Pure Power L8 CM Modular 80+ Bronze 250GB SSD Samsung 840 Series Thanks and greetings edit: As i crashed again i recognized, that there is no sound as if my computer restarts when i get a blackscreen but my graphics card immediatly gets silent after the blackscreen. After the blackscreen i can hear some ingame sounds which are lagging and after some seconds they are gone too. In this state i cant get my screen back to work when i press the restart button over and over again. I have to turn the computer off and back on, to get my screen back. edit: I also checked to set all video options to low. Still these crashes (but it appears that it takes longer to crash)
