It appears that NVIDIA doesn't support this card with its drivers. The card comes with the Dell Inspiron 8500. Dell hasn't updated the drivers for this thing since 2003.
Anyone point me in the right direction to get updated drivers?
Are you sure that it's not supported the same as the regular GeForce 4200 is?
If you really need the updated driver functionality, test the NVIDIA unified driver -- if it doesn't work, reinstall Dell's.
I have the same card on my laptop. Periodically I run the nVidia driver on it and it never gets updated. I think tthat's what Discalced is talking about.
When all is said and done, there's more said than done.
