Thanks a million to Csound1 for the awesome help.
After using Bootcamp to install Windows 7 Professional Full retail version onto my mid 2010 MacBook Pro, no sound would come out. Also the image on the screen was widened, distorted and too light. Furthermore, none of the buttons along the top row of my keyboard worked. For example, the eject button, volume buttons and brightness buttons would not work. The kind and professional 1 to 1 tutor found Csound1's answer on this forum and applied it. And then the computer and Windows 7 Pro worked perfectly. Thanks so much to Apple 1 to 1 and to Csound1.
The following answer solved my problem:
In OSX, use Boot Camp Assistant to download the drivers (1st option after you start Boot Camp Assistant). Copy them to a FAT32 formatted USB stick. Boot into Windows, run setup.exe from the stick.
