nVidia SMU and Ethernet Drivers

Hello, I recently experienced something bizarre, and I was wondering if someone could tell me what happened.

After installing Windows 7 onto my computer, I was looking through all the Apple drivers that were installed with the Snow Leopard disc, and seeing if there were any I didn't need. I removed the Trackpad drivers, and I noticed an nVidia driver. "I don't need that, I have the ATI card", I though, so I removed it.

The past month, the computer has run perfectly fine. But tonight, the Action Center pops up with a message: You are missing drivers for a component of your chipset, click here to download. I do so, and it turns out to be an SMU and Ethernet driver from nVidia.

So what I'm wondering is: what the **** is an SMU, what does nVidia have to do with the ethernet port, and why hasn't this message appeared for the past four weeks while everything has been running fine?

Nvidia reference motherboard used in Apple Macs.

Those were part of hardware abstraction layer (HAL)

The DVD contained drivers for any and all Macs and the only things I uninstall or disable or turn off are in

msconfig - startup items and services
services - there are one or two Apple found there that are optional
programs - before restart first time after Apple Setup I remove MobileMe and Bonjour at the least, too talkative and unnecessary for my use
