Base System Device??

I just installed Windows& from Vista. I have a HP Pavilion dv9930us notebook with a 64bit OS. Everything seems to be working fine except my nvidia video card driver cant be detected and also I am getting TWO control panel errors

Location: PCI bus 9, device 9, function 3

"The drivers for this device are not installed"

What do I do?

I downloaded all the Vista drivers (no Win 7 drivers available) for our ASUS X80L and the two missing Base System Device drivers were installed when I installed the Ricoh drivers (Ricoh R5C83x/84x Flash Media Controller Driver).
