One possible reason:

Is your nVidia card still living at that PCI address? That address is
usually hardcoded into your xorg.conf file, so if you move cards
around and PCI addresses also change, things may break...

$ lspci |grep -i vga

If it has changed, update your xorg.conf file and restart X.

Cheers,
Nick
