Firstly my setup

CPU: C2D E7200
GPU: HD4850
Motherboard: P5K SE/ EPU
RAM: 4gb corsair
PSU: Corsair 450w
TV tuner: Nova T 500
OS: Vista 64 bit

When I try to install the drivers on the cd I get the message

"Drivers have not been updated. Compatible hardware not found"

I have tried installing in both of the pci slots on my motherboard but still the same message.

What is the problem?

EDIT: Solved. I turned off automatic driver installation and problem solved! :D
