Hello friends, I recently gave my RX 580 ARMOUR OC GPU to a friend, which we just transferred from my build [see here: https://pcpartpicker.com/list/wq3Fwc] to my friend's, but it doesn't work for some reason. He's connected the 8-pin correctly and the fan's spin but there's no ready light on it and it won't post. He has a i5-9600KF CPU, 24gb RAM, 850 PSU, Z390 Gaming EDGE Motherboard running E7B17IMS.AC1 BIOS. Any help is appreciated!!
