    Default Z77X-UD3H Back USB Ports Not Working

    I was screwing around - removing programs and drivers trying to get a little extra speed - and now my back USB ports have stopped working. I've tried removing all the USB drivers in the device manager and letting windows rediscover them - no luck. I used the @BIOS to update to whatever it updates, then I downloaded this
    and this
    and this
    and installed them - none solved the problem. What should I try next? Thanks for your help.

    Do you have the On/Off Charge utility installed?

    If you do, uninstall that and then the two USB 3.0 drivers too. Then install the USB 3.0 drivers before you install On/Off Charge again.

    Otherwise you could try running a Repair from your Windows installation media.

    If all this fails, you're looking at a fresh Windows installation.
