I had exactly the same problem with mine (7600GT). Sometimes for me it would take over a minute, sometimes it wouldn't even get to the welcome screen at all. After uninstalling them the boot time was much quicker and it managed to boot every time.

Try fully updating Windows, then uninstall the nVidia drivers and reinstall them in safemode. Could be coincidence, but this has worked for both me and vaccination so it's worth a shot.
