Back USB 3.0 ports not working

I tried searching all over the place for the solution to this, but I can't seem to find it anywhere!

So I put together my computer myself from individually picked parts about 2 years back, and I've never really had any problems with it at all. However, I'm pretty sure the USB 3.0 ports on the back have never worked. When I plug my portable hard drive into one of the ports, it lights up, but nothing happens on the computer. Neither work. I have also tried plugging my mouse and keyboard into the ports and that didn't work either.

The hard drives I have are USB 3.0 and the connectors are blue and everything. I looked in the BIOS and the ports show up and are on. I'm running 64 bit windows 7, and my motherboard is Asus brand, not sure the exact model, but it has about 8 USB ports on the back in total, 2 of them being 3.0. All the other USB ports work except the 3.0 ones.

I don't really understand what the problem could be, despite putting together the computer, my knowledge is limited.

Thank you in advance for your help and effort.

    Try checking for a BIOS update on ASUS website, and while ur at it, make sure you get the latest USB drivers from there too.
  2. Check to make sure you have the USB 3.0 driver for your motherboard. They may be working, but not functional because you do not have the driver. The disk that came with your motherboard will have the driver, or you can go to the Asus website.

    Also, I do not believe that mice and keyboards work in USB 3.0 slots. Not entirely sure though.

    Hope this helps.

    Thank you so much! It took me awhile to get all of those things done, especially since I've never updated a BIOS before, but it was a learning experience and it solved the problem!
