My upgrade installation keeps hanging, so I ran the MS Upgrade Advisor. It's
telling me that my GeForce 8800GT video card is incompatible with Vista.
However, it's one of the most popular cards out there, with thousands of
users, so I find that hard to believe. Moreover, the manufacturer's website
states repeatedly that it is Vista-compatible. What's going on? And more
importantly, how can I fix it?
