I've got an AMD Radeon 7470 graphics card and I'm trying to run two Dell monitors using a DVI and a DVI to display port adapter. This has been working for years, but I recently moved and it is not recognizing the second monitor (the one using the display port). It gives me the error message (paraphrased), "This computer has an add-in graphics card, but the monitor is plugged into the integrated video connector." It then tells me to power down, plug the monitor into the add-in graphics card, and reboot.
Any ideas what happened from the last time I turned my computer off to now that would keep it from recognizing my second monitor?
