I think the point the OP is making is that after s/he moved the PC, the graphics card stopped working.
@Shankdoodle - Check to make sure your dedicated graphics card is properly seated into the graphics card slot and that any additional power cables are still connected. Then test your system with the DVI ports connected to the graphics card again.

P.S. Yes, the graphics card is wasted if your display is not connected to it.
