    USBs do not work until Windows 8.1 log in screen shows


    This is troublesome for a number of reasons.
    Can't access BIOS/CMOS.
    Can't go into Safemode.
    And sometimes, it takes a good 30 seconds after Windows 8.1 log in screen for me to be able to use USB devices. I say USB devices, but what I really need is my keyboard and mouse. Neither work.

    Yes, it used to. The computer is new, and was built by me. I changed BIOS settings, and that is actually the reason i'm trying to get into BIOS, to reset them. The BIOS settings are by MSI, by the way, and I changed them to a setting called 'fast boot'.

    I found something in the events viewer that may be related: "Windows failed fast startup with error status 0xC00000D4", relating the change I made in the BIOS settings.
    Also, "the driver \Driver\WudRD failed to load for th device SWD\SensorsAndLocationEnum\LPSensorSWDevice"

    Found this link: MSI USA H87-G43 64
    Apparently, it will help me access my BIOS!

    You can tell Windows (8) next time you boot goto cmos settings, hope that works, if not you may have to clear cmos (jumper on the motherboard) and start over How to Access the Boot Menu and BIOS in Windows 8 Operating Systems
