So if the card is properly plugged in it should provide the Video but if it's not properly seated the On Board Video is working. When you/r customer reseated the Video Card did they remove it and refit it or just push on it? I've seen a Back Bracket badly mounted on the card itself that was holding the card sightly out of the socket though it worked till the case was flexed which would move the card enough to pull it out of proper contact. I've also seen a brand of case with a lot of flex in it which would be marginal if any plug in card would actually work if it was so much as touched, if it was moved you had to open the case re seat all of the plug in cards and then it would work again. Just a long shot here but I would get the user to remove the Video Card and wipe the contacts with a Rubber/Eraser to clean the contacts and then refit the card. Make sure that the Bracket actually allows the Video Card to go all the way in and to this end I would loosen off the Nuts and after it's fitted tighten them again, there should be enough adjustment to allow the card to properly seat that way. I've had a couple of instances where the case was so bad that I actually had to replace it to keep the thing working though it was a specific Brand & Model of case involved which I just had to replace as any movement caused the cards to pop partially out. It worked perfectly here but when the owner got it home/wherever there was no video and when returned I had to re seat the Video Card. At first they said that they where happy re seating the card but eventually it got too much for them and I replaced the case. Though I have to admit that by then the cases where a couple of years old and maybe the rivets had come a bit loose with all of the flexing that it did.
