Assuming you never removed the card from the mother board, that should be that. Unless you knocked something around while moving the PC from one house to another.
Cant really see that simply unplugging and re-plugging the power leads to the vid card would kill the card, unless you were not properly grounded when doing so, and managed to give the card a bad enough static electric shock to fry something, but I am pretty sure you would have noticed if you did.
Edit: Just noticed you said you tested through the motherboard and everything worked. This implies that you have Onboard Video on the motherboard? It is possible that the Onboard video is conflicting with / takeing prioritory over your Video Card. You could check your bios settings to see if there is an option to disable the Onboard Video or force the system to use the Video Card rather then Onboard?
