USB 3.0 Ports Suddenly stopped working

Here's my build:

AMD FX-4 4130 3.8Ghz Quad Core
8G ram
AMD HD Radeon 7850 2gb Graphics Card
Gigabyte 78LMT-USB3 AMD 760G (Socket AM3+) DDR3 Motherboard
Seagate Barracuda 1TB 7200RPM SATA 6Gb/s 64MB Cache Hard Drive


I usually plug my Wifi Adapter into the back USB 3.0 port. However today the port suddenly stopped working. No matter what I did it wouldnt work.

I rang up overclockers (where I bought my pc) and they said I should reinstall the driver. I reinstalled it from the CD that came with my motherboard. It still didnt work.

I rang them up again, they directed me to this website: http://www.gigabyte.com/support-downloads/download-cent... where I can download the latest driver there. Still no luck.

Then they said I need to update the bios using a bios flash. I went to the website got the newest bios driver put it on a usb stick and applied still the USB 3.0 port wouldnt work.

Then they suggested to restore my pc to factory settings and reinstall windows all over again. I painstakingly did that and installed all drivers from the CDs. At this very moment I am installing the remaining 200+ windows 7 updates. Even now the USB 3.0 still isn't working. I'm beginning to think that the usb 3.0 port is damaged somehow.

What can i do?

check in the motherboard bios that the usb 3.0 ports are turned on. then try another usb device to rule out the port or the wifi adaptor. also check that there no damage to the usb port. if the port wont see any usb device then the chipset on the mb has failed and the mb needs to be replaced.

All my other usb ports work. I have two USB 3.0 ports that don't work. I checked the bios it says the USB 3.0 is enabled. I guess it really is damaged.

If I ring overclockers up, do you think they will just ship a replacement motherboard or will they ask for me to return the motherboard back to them for analysis? Because the latter is just a pain in the backside.

the company should send you a new mb if it the front two ports that stopped working check to see that there still plugged in. also check to see if you added a card and the card causing issues with the mb. try removing the last card that was installed to see if the ports turn on.

Oh it's okay guys I finally made it work this morning. I just tried installing the usb 3.0 drier from the CD one more time hoping it would work. And what do you know it finally did. I checked in the device manager and there was no warning message for the driver.

Thanks for the help guys!
