Uhh just bought this Dell on eBay. The GPU is an AMD Radeon 7000 something. And it won’t come out. In the smaller red circle is the white clip and that was the best angle angle I could get.
Does the the clip move, but the card won't come out? There might be screws at the back of the case somewhere holding it in place.
Push the GPU down towards the MB and push down the white tab at the same time, you might have to wiggle the card but it should come loose.
