This is not the driver to support your nVidia Geforce4 440 Go which would normally be read as an nVidia Geforce4 440MX (depending on the software) The driver this link downloads is not compatible with the GF4 440Go at all- heck- nVidia doesn't have a link that DOES support the card. I eventually found an update to my card's driver at the HP.com site which brought my card up to v7.2.3.0 which was last updated 2/23/05. Nothing since then and there are no detonator drivers in beta waiting either. nVidia and ATI for that matter should clean up their line or make it more than clear as to which cards have updates.. Then create an exhaustive list of supported hardware.. Even in an unsupported section you should list everything that's, uh, not supported. Don't make me guess forever whether my card is the same one that has a MX vs. Go in the name. Functionally they are the same thing it appears.
