I'm just checking on which chipset drivers to use, Dell's download page has the chipset drivers for Precision 390 Vista 64Bit version 8.1.1.1010 so installing these drivers installs them ok with installation activity if you knwo what I mean, I have cleaned installed and decided to install the latest chipset drivers for my chipset 975x from the Intel website but when I install these drivers it does not go though the installation process like the Dell chipset drivers did, just takes 5 secs and says installation complete.

Is this becuase the Dell chipset drivers have been modified or something apposed to the Intel chipset drivers?
