    One USB port not working after power surge?
    « on: April 21, 2013, 08:44:59 AM »
    I have 2 USB ports in the front panel. One is a 3.0 and the other is 2.0 . One has a mouse connected to it and the other has a wireless adapter that i use for internet access. I was sitting normally PC when my leg accidentally hit a wire which cause the whole PC to shutdown. After the restart everything seemed to be working except the 3.0 USB port in the front panel that had the wireless adapter. All other USB ports are working fine and i am not finding any problems anywhere else... What can i do to make it work again?

    I would remove all power and open a side panel to the case to see if the front header USB lead was dislodged...
    If it has any scorch marks i wouldn't use it any longer.

      Okay i was wrong. The problem is far worse.. ALL my 3.0 USB ports are not working ( 2 in the back 1 in the front ) ... Only the 2.0 are working... What can i do?

      EDIT :

      I checked the BIOS and the USB 3.0 controller is enabled... Still not working.

      Then the USB 3.0 port on the MBoard is what shorted out...
      See if there is another one you can use...if not you will have to get a PCI-E addon card...

        Okay i managed to make it work again. I checked the device manager but everything seemed fine. So i what i did was that i shutdown the PC then pulled out the Power supply cord and  tried booting the PC by holding the Startup button ( I read somewhere that this uses the +5V that the PSU has running when the PC is shutdown and sometimes fixes some bugs ). After that i replugged the power cord and started the PC normally. Opened the device manager again and this time there were 3 USB ports that had yellow "!" next to it. So i uninstalled and restarted the PC so that they automatically install again and everything worked fine.. All 3 USB ports are now back up. I hope this solution is useful for anyone else who faced a problem similar to me.

        Good to hear you are fixed up...
        Never heard that one before.
