So if it is a hardware failure, it has worked perfectly since I got the board a year ago and failed after I updated and rebooted this afternoon. Can't say that didn't happen, but it seems really co-incidental. I'm assuming the southbridge chip (or whatever it is called) > is dead or at least half dead. X570 is an AMD AM4 motherboard. I'm running a Ryzen 3600X processor. System has been rock solid since I fixed a power supply issue a few months ago. The USB2 ports do work. > > The other hardware failure on this is the onboard Intel video > which I guess must use the same half dead chip. > I have an NVIDIA GTX 1080 Ti video card.
