Vista 32-bit

Hi everyone. I just joined the forum because I am in desperate need of help.

I want to upgrade my system from vista ultimate 32 bit to windows 7 (preferrably 64 bit). I ran the upgrade advisor tool from microsoft and ran into a big problem:
my nvidia graphics card isn't compatible, and it says it cant' find the driver to make it compatible.
So, I did some research, and discovered tons of other people with sony notebooks have the same exact problem. Sony won't provide new drivers for anyone, and attempts to contact them result in the same hting: your computer was designed to work with vista only.
My computer isn't a notebook per se, but it has all notebook components. I have a Sony all-in-one desktop, model VGN-LT29U. I have 4 gig of ram. The graphics processor that's supposedly not compatible is the NVIDIA GeForce 8400M GT. Driver version is old, it's 156.65. Like I said SOny isn't any help. I looked up my GPU on Nvidia's website, and there is a new version available as of last month (version 195.62), but if you look in the release notes, it says that "Sony notebook users should not use this upgrade, and should instead contact their manufacturer for updates".
I really need help here folks... I want to upgrade to Windows 7, but I have questions/problems. Does this update from NVIDIA fix the compatibility issue? If so, is it safe to update my Sony All-In-One computer using NVIDIA's update considering the note about sony notebooks (like I said, I know my computer is a desktop, but it uses all notebook components, including this mobile GPU from NVIDIA).
Anyone out ther ewho can help me out, or point me in the right direcion of a sure-fire way to fix/update my graphics card so its definitely compatible with windows 7?

Hate to beat an old thread but I think NVIDIA finally released a proper Win 7 Driver for the GeForce 8400M GT. Link is below:


Can anyone confirm if this worked properly? I ran the win 7 compatibility tool to see if there had ever been an update but it still claims the 8400M isn't compatible but when I check Sony's Vaio customer support site, it says my Vaio is Win 7 compatible now.
