I've just bought a new computer, and I am still in the tweaking in process.My problem is I can't seem to get any games to run after I've installed them. Two examples are: E T Matrix ,the error is Full screen mode not found. Rainbow 6-3d hardware not found use directx 8.1 or greater. (I'm running directx 9) System- P4 2.8 875 pbz intel board 512meg ddr400 kingston hyper X Radeon 9700 128 card
