sound and graphics issues

I'm trying to get compiz working, but when I go to adjust the settings it says my system does not support 3D desktop effects. I know my hardware will suport it, it's just a question of getting the right drivers. I'm currently running Mandriva 2007 on an hp dv6000z laptop with a nvidia gforce 7200 graphics card. I've run into several texts dealing with nvidia and linux but when I go to the nvidia website to get the driver there seems to be only one uniform nvidia option for linux. Any help would be appreciated. Oh one other issue, my sound skips like crazy and is for the most part intolerable. Any help or direction would be greatly appreciated.

Thanks

post your xorg.config file, its in /etc/X11/
