Installed a recent update of windows 10 instantly ran in to problems, keyboard and stopped working then usb xhci compliant host controller had a code 10 error. Tried reverting the update wouldn't let me another issue is that my computer will not shut down or restart at all unless i hold down the power button. I have reset my pc nothing installed Windows 10 again nothing, tried to use Windows 7 but can't use keyboard and mouse. Any ideas ? Motherboard issue or software?
