I just bought and installed Half Life 2. When you start the game up the picture of the guy with the knob in his head shows up, then the copywrite screen, the loading screen appears for just a second, then I get an error. Says, "Failed to set video mode - Falling back to safe mode settings" it repeats 3 times then says "Failed to set video mode" and on the line below, "This game has a minimun requirement of DirectX 7.0 compatible hardware." I have DirectX 9.0. I have the Nvidia GeForce 5700LE 258MB video card with the newest drivers downloaded. What is the problem and how can I fix it? I just spent $70.00 on a game I can't play, pls Help!
