I got a working graphics card and my computer wont recognize that it's inserted. It is connected to the power supply properly. It is a NVidia Geforce 275 896M (Yes, I know that it's old), my motherboard is an Asus Z170 Pro Gaming, and my power supply is a Corsair RM550x. Thanks in advanced. I also accidentally pressed the best answer button the last time I asked. It was not solved last time.
