Computer will not update video card driver or iTunes help?

So. My computer (Windows 7) has never been good about updates, especially with iTunes. I've tried to update iTunes multiple times over time, and it never works. Now that iOS 5 is out, I'd like to update my iPod, but it says I need iTunes 10.5 (I think I have iTunes 10.2.something). Every time I try to update it it fails. Id also like to update my video card driver so I can play minecraft, but I tried to do it through windows updates, and that fails every time too. My video card is a NVIDIA GeForce 6150SE nForce 430. How do I fix these update problems? BTW Im pretty sure it is NOT a virus, we run a VIPRE Anti-Virus scan everyday, and it's always clean.|||This link will take you to downloads of iTunes 10.5 32-bit and 64-bit.

This is what I found when I clicked the Search button:

You'll notice on the previous screen there was an Option 2: Automatically find drivers for my NVIDIA products.



Hope this helps.
