audio, keyboard and trackpad not working on vista sp2

my macbook's audio( just an X mark on the audio), keyboard and trackpad are not working. although when i switch to leopard and/or BIOS they are still working
i already tried reinstalling bootcamp. updating the driver and scans for any hardware changes. and even used driver scanner (although i think this is where the problem began)

is there a way to fix this?

thnx

It sounds like you didn't install the drivers that you need. Did you insert your Leopard DVD after Vista booted up for the first time? Drivers are installed automatically from the Leopard DVD.

yep i installed them. i think the problem started after using uniblue driver scanner

Try uninstalling the Uniblue driver scanner to see what happens. If it's causing the problem it may be that it installed some incorrect drivers. You'll have to find them and remove them.

Or you can open the hardware tree, right click on the problem hardware, (audio, keyboard, trackpad) select properties, and then select "roll back driver".
