NVIDIA Compatibility Problem

[Sleepless in St. Louis]

When attempting to ugrade XP Home Edition to XP
Professional, the Windows XP Upgrade Compatibility, stops
the install as follows:

NVIDIA AGP filter
=================
The currently installed driver for the NVIDIA NForce
device is not compatible with this version of Microsoft
Windows. Setup will not be able to complete.

I have downloaded the latest NVIDIA driver but the
compatibility warning is still there. Actually, my
NVIDIA driver is a GeForce 4MX 420. I have checked all
over the support site and can't find a match to this
problem. Any help appreciated.

Could it be that you are not using a WHQL certified video card driver??
