Hello. As the title says I've recently switched my household computer's graphics card with my friends card, as our family computer doesn't require something quiet as powerful as what we had in it. I swapped a AMD 7950 from my family computer and replaced it with a little nvidia card (I don't remember the model off hand but it was one of the tiny ones with 256mb memory and no power input).
they were both pci-e 2.0 and when my friend popped my card into his computer it worked fine except for a few directX errors. When I got home and put the nvidia into my families computer I got no video at all. The card worked when I left my friends house and I know the monitor and cables work as I tested them with my laptop. I tried every port and reseated it multiple times and nothing worked.
The machine it's being installed into does not have on board graphics so I can't do anything with it without a video card. My friend suggested it may have gotten damaged on the way home though that seems unlikely, I transported it the exact same way I transported my AMD card so it shouldn't have been a problem.
At the moment I cannot think of anything else I can do other than replace the video card entirely, though I would like to avoid this if possible. Thank you for your time, any suggestions would be helpful.

It's most likely a conflict of drivers, switching from amd to nvidia. I would recommend uninstalling catalyst control center and other related amd drivers with the amd card still in the machine. After doing that, then try installing the nvidia card.
