    It was working perfectly before but ever since returning from winter break it now can't make it half passed the bios startup. I can't even enter the Setup or the Boot menu. This honestly came out of no where.

    apparently it's 2,3,4

    A possible USB failure has occurred.

    Reinstall all USB devices, check cable connections, and then restart the computer.

    I'm not sure how i'm supposed to reinstall USB devices when I can't even start the computer pass bios tho.
