I'm experiencing a problem with my laptop screen. The screen goes black every time I launch a game, or sometimes even launching windows. The screen does not go completely black, I can still see the screen if I look carefully. It seems the brightness has drastically decreased and I can't adjust it back. The computer is obviously still operating, but with severely decreased scree brightness. I have downloaded the latest video card driver and it does nothing.
My lap top is a HP Pavilion dv6220tx with Windows Vista Ultimate 32-bit and Nvidia Geforce Fo 7400.
Does anyone have a solution to this? Its been bugging me for the last few weeks...
