What's the problem

" I works with Toshiba satellite M100 with preinstall Windows Vista home basic edition operating system. When I switch to Windows XP pro SP2, My sound card does not works and In the Device Manager I also got some question marks on the Mass storage controller, SM Bus controller and Modem Device. Of course they also do not work. I have downloaded drivers from Toshiba support website installed them but still don't work ? Can somebody help? Thank you. "
