Nvidia Unified Driver a.k.a Inconvenience

Today I was trying to fix a sound problem with my PC.
Since I have a NForce 2 chipset, everything in it is Nvidia. The Ethernet card, the sound card, the PCI controller, everything. I recently installed an Nvidia AGP Graphics Card 6600GT(GC).

So I unistalled the drivers, rebooted and installed them again. And after the Windows logo, BOOM! Black screen! Windows were there but not on my screen. So I changed the output to my screen to DVI instead of the analog one. Nothing changed. Reset. Safe mode. Unistall the Video card Drivers, reboot. Install the GC drivers, reboot, black screen! Okay... Reset AGAIN, and in Add/Remove Programs, a great surprise. There was only one option to Nvidia Drivers. Uninstall, and guess what: There was a choice to unistall every driver separately. Why this wasn't available in the first place?

As I was searching the install folder I found out that the Unified Drivers had their own GC drivers installed. That's what made the conflict and wasted my time reseting and rebooting my PC.

Why didn't Nvidia made the single most easy choice of to choose which drivers do you want to install? And why did it do that to the Unistall feature only?

What they were thinking? The GC drivers are 64.1mb and the Nforce Unified are 24.1mb. Is it the same? Hell no!

Seriously I was so much pissed off that I was ready to reinstall my ATI VGA Card...
The thing is that I had changed my GC from ATI to Nvidia, and never had encountered this problem before. Imagine having that after you have formatted your PC!
