nVidia nForce unified driver package wouldn't auto-install

[Nocturnal]

A8N-SLI Deluxe

Any idea why it wouldn't automatically start the setup.exe? Even when I went to the directory that it had installed the files to, when I clicked on setup.exe it would give me the splash screen then it would disappear. I'm hoping this is not a hardware issue. I just formatted and re-installed Windows. Any ideas?
