That won't work. His GPU isn't supported by those drivers.
@OP: I've looked deeper into it and I think your GPU is not supported in windows 8. If you want to use them, you'll have to stick with the generic driver.
Indeed those drivers dont support that gpu I just noticed that aswell.
Here are the latest drivers (vista) that I can find that MIGHT work: http://www.mediafire.com/?t0mrw1c3nig
Its a small chance that it will work but you can give it a try, good luck.
