I have an amd r7 450 graphics card but my pc does not detect it, before I had a dell optiplex 790 with an i5-2400, this pc did detect my graphics card and did not present any problem, however, on any other pc that I have tried it turns out for not recognizing the card, I currently have an optiplex 7050 which does not seem to recognize the graphics card in any way, the fan turns on but does not send an image, it starts with the integrated graphics, on the other hand, trying an r5 430 it does recognize it, and again, my previous pc does recognize the graphics card without any problem so I assume it is not damaged
