So the other day I was trying to sync my iPhone to my computer and the USB ports just shut off and turn back on a couple times. (You can hear the sound when something is plugged in and unplugged) Then I tried updating a game and realized it did the same thing. I have a USB wifi adapter. It seems that when heavy data is going through the usb ports they just quit working. Do I need a new motherboard or what? I checked device manager for updates and nothing came up. I tried googling as well but I suppose my issue is too complex for google to find what I'm looking for. Any help is appreciated. Thanks.
