I installed Windows 7 RC a few days ago and I am very happy with it except for one thing, and that's when playing games.
When I have played for some time (it's totally random) the screen goes black and it refuses to display the image again, tried unplugging it from graphics card, turn off power and nothing helps. The sound continues but nothing else respons.
This happens in all games i've tried this far (Prototype, Overlord II, Call of Juarez - Bound in Blood). It never happens when I'm simply using Windows or programs, only when I play games. Windowed Mode also seems to work without the screen going black, but unfortunately all games doesnt have an option to play in windowed mode.
I have all updates from Windows Update installed, latest graphics drivers
and DirectX. The graphics card is quite hot when I touch it, so is it possible that Windows 7 is very sensitive to this? I never had this problem in Vista and it appeared right after i formated the harddrive and installed Windows 7 RC.
Any help is appreaciated, cause this is really starting to annoy me.
