I recently got gifted a secondhand computer which happened to have a better gpu then the one I had so I swapped them out I had installed all correct drivers for the new gpu uninstalling the old ones and kept running into issues with certain games so decided to put my old one back in which I’ve never had any issues with but now with my old gpu back in I have no display and no usb power. I have no bleep codes or lights other than a dram light of which isn’t showing anything wrong I tried clearing the cmos and that hasn’t worked does anyone have any suggestions?
