ASRock Extreme3 Gen3 Z68

Everyonce in a while, my computer won't boot. It gets stuck at the ASRock screen and Mr. Debug has a B4 on it. Usually when I restart it, this doesn't happen, if it does, I just hit F11 and select my hard drive and everything is normal. What's the B4 for again?

    I believe this is some kind of hardware issue related to USB.

    Here is a thread about the same issue, just on a different ASROck board, but same error code

    Here's a solution one person said worked for him.
    Read the "How To Update" for L1.23, save file to USB drive, follow instructions to flash bios. GOOD LUCK
