I tried "baking" my card in the machine. My iMac would stay on (gray screen) in safe boot mode, so it would heat up on it's own. I turned it on and laid it flat on the screen for about 20 mins, hoping the internal heat would help reseat the graphics chip. (Seemed from the videos I saw, we want the chip to move down towards the front of the computer)
Really I was just hoping for it to work for a few minutes while we grabbed some much needed files.
After a few attempts, the iMac is up and running. It's been on all night syncing files to the cloud. I'm sure this is a temp solution, but might be worth a try if you're not prepared to take everything apart.
