hey..i already installed the driver..but still cannot change my display to ATI..and i tried to install guitar hero 3 game just to see if it can play..but sadly no..it said that d3dx9 is missing..but in my previous windows vista..there is no problem to play the game..but in this win 7..there is a message said that d3dx9 is missing..why??does this mean my ATI graphic card is not detected??or there's some setting that i need to change??
