Answer to: USB's not working, unable to use any inputsI’m not sure why. They gave me no hassle as it was only a month old and the warranty is for three years. The board is only $180 brand new so don’t do the $300 repair :-)
Answer to: USB's not working, unable to use any inputsHe finished the diagnosis today: motherboard failure. Called Asus and it has a 3 year warranty so they gave me a RMA number and I'm shipping it to them. They'll send a new one. In the meantime, my guy installed a bit 'lesser' board to get me back in business until the new Z270e shows up and we'll put that back in. He was able to use the USB-C connector but the computer wouldn't respond to a flash drive plugged into it. It crashed hard.
Answer to: USB's not working, unable to use any inputsExact same issue here tonight. So frustrating. Got an old PS2 keyboard and trying to figure out what to do. I have checked the connections and nothing has changed since it worked perfectly last week. I didn't see the Windows 10 update happen, but maybe that's the reason? Glad to find your post and I hope we both find an answer. Barry
