Thread: USB port problem

  1. #1

    Default USB port problem

    Having this strange problem with USB ports in my desktop. If i try to connect more than one USB device into the front or back port, the devices already connected to the other ports lose their connection and do not get recognized until I remove the new device or restart the PC altogether. Can anyone shed some light on why this might be happening?
    I suspect the PSU might be behind this (my GPU got fried recently and the internal DVD rom does not work properly if i connect it ), but all the other component are working fine. Thanks in advance

    Sounds Like your motherboard circuit caught some problem. You sure with the driver issue have you installed chip-set inf utility and check if there is any unknown device showing in your driver manager of windows.

    You better take your PC to the doctor ask for a full checkup.

    Disconnect the front USB wire from mobo and try USB of your CPU back panel, if problem remains try with mulit-port active USB HUB.

    @Metal Like i mentioned earlier, my GPU is fried already, so obviously i removed it.

    So far i switched the front USB connection to an alternative port, but after I did that the computer does not pass POST. Onekkhon ATX power cable niye tanatani korar por it sprang back to life. However the problem still remains though :/
