On a HP Laptop running 2k w/sp4, I installed the O/S then the updated driver for the nVidia GeForce 440 video chipset (from HP's site for that notebook) BEFORE I installed DX9 and lost the pointer and use of the keyboard. No other drivers or s/w was installed. I uninstalled the video driver, but no luck. As I remember you can't uninstall a DX update, correct? I don't know if it was the DX9 or installing it after the video driver where the issue lies. I can get inro safe mode and the keyboard and pointer are ok there. Besides playing musical chairs and disabling drivers one at a time is there something else I can do?
