Problem nVidia GeForce 8400 gs

[Simpson]

After much searching and not finding anything I had decided to make the query.

Today when you turn on your PC, I find that the screen resolution is 800x600 and color quality of 4 bits (not what he had ever seen)
I reinstalled the drivers updated Web NVIDIA, the first in Castilian and then in English and nothing at all, everything remains the same.
If you uninstall the NVIDIA driver and I take the generic, but I can not use two monitors and the resolution is lower.
Is there anyone who has suffered the same thing ?...¿ How can fix it?
Thank you all in advance.

When I install the nvidia driver I always use lower resolution and bit depth color, I just go back to putting as I like and ready.
