display suddenly gone wrong

Archived from groups: microsoft.public.win2000.general (More info?)

Hello:

I'm running Windows 2000 with an Nvidia GeForce 440MX graphics card.
Yesterday, having done nothing unusual, I started up the PC and it told
me that it had miraculously "found new hardware" -- Nvidia Dualview. At
the same time I find that my display has gone wrong. Resolution has
been set to 480 x 640, I can't run any programs that require DirectX,
and in my display settings I can't change from 16 colours. I don't know
what Nvidia Dualview is and I don't want it. I just want to get back to
where I was before.

Can anyone help me? What things should I try?

Thanks.
