I built a computer last year and for the most part it's been working fine. However, there is one particular usb 3.0 port on the front that's been giving me headaches: when I plug in my portable hard drive, sometimes the computer will just turn off! It happened mostly during last winter when I first built it, but it's been happening lately too. I've taken to discharging the electricity every time I plug in the device, but I still notice issues every now and then. Just recently, I had to re-install the usb drivers because they had some kind of error. I'm not sure if there is something wrong with the port, motherboard, hard drive or perhaps the outlet itself, but I've only seen it happen on the 3.0 ports and I'm worried about what the problem could be. Is there something else I could do to prevent this?

Are you sure that when you plugged the cable to the front USB3 ports that you inserted it to the correct connector on the motherboard? –  Dan D. Nov 9 '13 at 17:09
    
Last I check they were but I'll look again. If it wasn't properly plugged in, would it even work? –  user271806 Nov 9 '13 at 17:21
