I recently bought a new pc (specs: Windows 7,1TB Hard drive, 8gb Ram, I7 Processor and Nvidia gtx 560ti graphics card). I have bought three different games all of which minimise and exit to desktop every 2 or 3 minutes. Does anyone have an idea of what the problem might be and how to fix it? (I will post this in the games forum aswell in case someone can help there)
Having an anti virus or spyware programme running at the same time can cause this problem. Especially AVG. Try shutting down or disabling any security software you have running whilst you play, and see if it makes a difference.
Or do you have a slideshow running as your wallpaper? This will minimize your game every time it changes.
