In the control panel -> Hard ware first uninstall the current drivers,
reboot press F8 choose save mode.
Use Driver heaven's Driver cleaner pro, choose nvidia and clean.
Reboot to normal windows and
Go to
http://www.laptopvideo2go.com/ to download the drivers which support the Go card.
Like Matth told you
Install drivers wich are suittable for your Go card.
Thats the whole procedure.
Hope this helps
