    2,3,4 are usually a USB failure?  Do you have any usb devices connected?  Like an external hard drive, printer, mouse, keyboard etc?

    Unplug them and reboot

    Based on MASQ's comment, DISCONNECT all USB devices EXCEPT keyboard and mouse - if possible, connect the keyboard and mouse to different USB ports.
