I'm sorry how do I check my bios revisions and yes I'm sure I have I also tried installing all drivers with the z270e disc that came with mobo I've tried letting windows update install all drivers and I always get the same error on the same driver none of my USB ports work they won't pick up mouse or keyboard but if I plug say a external hard drive into one of them it will power on but the pc won't pick it up and yes I think everything shows in device manager I'll add another photo running windows 10 pro
