I ran half-life 2 successfully in the past on this computer. I recently reformatted and just reinstalled the game. I get the blurry "Loading..." screen, then it goes to a start screen with a bunch of Cartesian graph-like lines. You can see a grid outline of a guard walking around, and it makes the sounds when you mouse over the areas where there should be menu items, but you can't see any text or details. This is on an eMachine T3256 with nVidia GeForce4 MX and 512MB RAM. Drivers and windows updates are all current. Any ideas?
