lost opengl driver on laptop

On my laptop there isn’t any opengl driver!

I’ve a Dell Inspiron whit a Nvidia GForce 4 4200 Go; I’ve installed the latest video driver released from Dell but Neverwinter Nigths don’t find any opengl driver installed!

What can I do???
the nvidia official driver don’t support laptops video cards, is possible that the driver from Dell support only DirectX???
