I have had Half life 2 on my computer for some time. Decided to try counter strike which is the game which accompanies the package. It told me I needed to update my video driver. Which I did. Then it told me I needed Direct x 7. When I went into the homepage I think the most up to date was direct x 9. Installed that. Went back to start Half life 2 and the first screen came up and then crashed more or less straight away. Then when I pressed icon on desk top again it refused to do anything. Or counter strike. Any ideas?
