After days of unsuccessfully installing my GPU, I finally figured out what the problem may be. I think I need to change the default graphics output to PCIe on the BIOS menu but every time I try to save this setting it automatically switches back to auto on reboot. No matter what I try I cannot get the GPU to show up in Device Manager. All of the components are new or manufacturer refurbished. This is the first PC I built myself and I really want to figure this out and move past this frustration!
