I have a friend with a weird issue. He has a xeon 1231v3 on a h97 mobo, 650W Corsair 80+ bronze psu. Currently has a GTX 770. When we try to install a newer GPU, its black screen, no image comes up when powering on the computer. We have used DDU Installer in safe mode, Clear Cmos, Updated Bios, Fresh Windows Install. We have so far tried a GTX 950, 970, 980Ti, 1070 and RX 580. All same results. Im at a loss
