hey GA-P75-D3 is the mother board im using, this mobo is so old it doesnt have display connectivity, not even VGA so i used to have a RX 570 as the displayport but i recently ati flashed the gpu bc it wasn’t working with the patch. i boosted the pc and the lights in the pc run but not my mouse, keybord or monitor. i read this one post from other sorce and this guy claimed that he used a usb to update his motherboard without display with the same gpu and mobo as mine. CAN someone how me or know what is this guy talking about usb in a motherboard?
