HI Everyone, i am install win 7 ultimate activate using RemoveWAT. After i try to install all imp s/w and also try to install games like NFS underground, quake4. installation completed successful but after i click the icon to play games it show NFS or quake stopped working. those games are worked well in vista. and any other certain small games also not working. is it any video driver issue becoz ATI radeon drivers automatically installed. where can i download latest ATI drivers for win 7? i search in various downloading sites but its not suitable.
