hi there.
I upgraded my gtx 750ti to an Rx 570 and deleted all GPU drivers with ddu and when I installed the Rx 570 my monitor will show a black screen and then I installed my gtx 750ti back to my motherboard and it shows signal without any problems and I have a good PSU I don't know why is that happening any help will be appreciated

Does your PC boot with RX 570? In opposition to RX 570, GTX 750 Ti doesn't require any additional pin connectors from PSU...

So make sure you connect PCIe power connections and getting signal from correct interface like HDMI.

ok, I figured it out turned out my Gigabyte GA-P75-D3 mobo was outdated all I did is update the bios using USB flash and boom the Rx 570 started working hope this works to anybody got an old mobo
