It is HL 2 I attempted to validate the integrity of the game cache but no luck. I have a ATI Mobility radeon 9600 pro turbo. I also tried to reinstall but its still giving me the boxes.
When ever I see a light in half life there is a strange white box with an x in it. It's like i'm in a debug mode or something strange. Any ideas for a fix? Its really annoying to see boxes all over the screen.
