I bought a xboxcontroller for my asus g73jh. Now after a few days one usb port doesn't work and if I plug anything into my computer shuts down, and sometimes it wont turn back on unless i take the battery out. But I cant plug in the controller into any other usb port, but I could before. And if I plug anything into the other usb ports there is no problem.
There is only one dead port? Put tape over it and use the others. If there are more than a few dead ports you can try to reset the BIOS (which sometimes clears things up), otherwise you need to replace the motherboard.
