Just received brand new Rx 570 Nitro+ from amazon a week ago, installed all the parts of the rig and when i wanted to try the GPU the GPU Sapphire logo's light is on but HDMI doesn't display anything, it did display before Updating the Motherboard Bios and Installing windows 10 64 Bit.
I accessed bios of Motherboard "MSI" to see if there's anything attached to the PCIE sluts but seems like motherboard can't see the GPU at all.
