Well, not all games can be played in the fullscreen mode since the game can not fullscreen a video card that is only DSI, so, most video cards will have a problem, but if you change the video card you have to do this again and this time after the game starts in windowed mode. The most suitable video card to play fullscreen is an integrated one (for example Nvidia and Matrox)
The solution to this problem? Just do a little mumm about time and the simple and requires a small amount of money and not a lot of technologies, although it requires patience to test in different possible video cards that can be expensive, if he is an ATI card that has the previously mentioned problem, check the place where the video card is located. If you know where the video card is at the back of your computer, remove it, and insert it in another place.
Can a video card not work while you're running another? Good question. Well, it's because the video card owns a library (memory) that contains all the on-screen information it shows whenever you play the game. When one video card is Statically built, the video card usually fails to provide any extra data that can be managed by another board. And when the game is running in the fullscreen mode, the game needs all the information. It includes the information of the whole display, so if you leave the video card, you also need to move it. Normally, the video cards of integrated boards, if there is a problem at the last, they behave regularly with their siblings. If the problem is a faulty driver, the best is to repair it and check if the video card is still okay in that mode. d2c66b5586
