I suppose the first step is to get your system back to a working state. Or have you already?

Can you boot up in safe mode? If you can, do a system rollback.

If your card works on the previous nvidia driver, and not on the newest, then I'd stay with the older version. Sometimes new drivers have bugs. Happens.
