Mobo:  Gigabyte GA-970A-DS3P

Memory: 2 of Crucial Ballistix Sport 4GB Single DDR3 1333 MT/s (PC3-10600) CL9 @1.5V UDIMM 240-Pin Memory BLS4G3D1339DS1S00

CPU: AMD FD6300WMHKBOX FX-6300 6-Core Processor Black Edition

OS: Windows 8.1

 

So I have plugged things into all of the USB ports on the front of the case, which are wired to the motherboard.  There is more than one cable from that case front for the USB ports.  1 on the case is 3.0.  There are Four USB total on the back that work and all of them are USB 2.0.  The USB ports on the second row down do nothing when something is plugged into them.  A row below those are USB 3.0 ports and they don't do anything either.  I did discover that I can charge a device from any of these, though.

Looking at the images on the Gigabyte web-site the rear panel sockets are hard wired into the motherboard so there is no possibility of a wiring error. Looks like you have a faulty mobo. If this is a recent purchase, probably worth taking up with your supplier.

O how I feel your pain.  I have a Gigabyte Z77X-UDH3 that had 4 out my 6 USB 3.0 ports, after almost two years of no PC issues, fail virtually at the same time. This is what Gigabyte support had me do and I am sure it will help you in your diagnosis.

1. Reboot your system into BIOS and while in BIOS try your keyboard in the slots that failed and see if your keyboard works in any of them.
2. Reboot into Safe Mode and repeat the process as in #1.

 

My keyboard failed to work in both BIOS and Safe Mode.

* Then get a hold of Gigabyte's tech support and report your issues plus the diagnostic findings. When Gigabyte saw the results that issued me an RMA.

* In addition I burned Linux Mint to a DVD and rebooted my system with said DVD in my DVD drive. Linux loaded before Windows could. Don't worry it doesn't harm your system or Windows at all. My keyboard failed in the slots as before.  You don't have to do this though; it was an extra diagnostics I did for myself.

 

* Also, if they do authorize an RMA make sure you place it in an antistatic bag and whatever you do make sure you put the plastic cpu protector back on the motherboard.

It might be a good idea to first: visually inspect all of the USB ports for damaged pins or shorting pins. It is easily possible to plug in usb flash drives or cords inocrrectly and damage/bend pins so they short. A single bad usb port could be affecting all of them, I see this all the time. They might not RMA the board if it has a physically damaged USB port, I have never sent a board in due to this so I can not say for certain.

 

If no pins are bent or shorting in any of the usb ports, test a keyboard to try and get in the bios as others have mentioned. If no usb port works with a keyboard at a bios level, your board has a problem and you should be able to rma it if it is still under warranty.

 

Also do not forget to inspect inside of the computer look on the motherboard where the front usb ports plug in (usb header on the board). Inspect the open usb headers as well. I have seen some bent usb header pins on a board, the usb ports were not working. The pins were touching (shorting), I bent them straight so they were no longer shorting and it all worked again.
