WHAT TO DO?
If your v-card is not on-board, check it if it is not loose (maybe its just a loss contact). Remove your video card and clean its connections using a pencil eraser and re-insert it to its slot. If nothing happens try to insert the video card into another computer, if that computer will display then your slot for the video card is defective and your best option for that is to buy another motherboard. Doing in reverse, try also to insert another video card to your defective unit (make sure that the video card you use is functional) By doing this, you can identify whether your motherboard is defective or your video card.
If it is on-board, then your best move is to buy an external v-card that will will to your motherboard (maybe its an AGP or a PCI-E).
