Both USB 3.0 ports no longer working after power surge

Last night, I was working on my computer when the electricity suddenly went off for a few seconds. I booted up my computer again and all of a sudden, the USB 3.0 ports don't work. I have an external hard drive that I keep plugged in that the computer would not recognize. The light turns on, but it is not opened by the computer. The hard drive works fine on any of my other 2.0 USB ports. Neither my mouse or my keyboard work on the 3.0 ports.

I've checked the BIOS, I've tried uninstalling them, I've tried updating windows and nothing seems to work. I have an Asrock 990 extreme3 motherboard. I tried checking the website for updated drivers but when I tried installing them, I got an error message that there was already a driver installed and that I had to uninstall it, and then reinstall, but I can't find where the first driver is to uninstall it.

Under my device manager, there is an error under unknown devices that has the yellow triangle "Universal Serial Bus (USB) Controller." I tried uninstalling that but nothing happens after that.

I feel like I tried everything I could find and nothing is making them work again.

I'm running Windows 7, 64 bit. It's a custom build, so it's been hard trying to find what specifically is the problem. If anyone has any idea on how to fix this please let me know! Thank you!

No problem. Anyway unfortunately that damage is permanent so you better buy an external USB 3 hub to replace the damaged ports. Good luck.

Probably the power surge caused either the USB3 connector on the motherboard or the USB3 on the case to short. The only way to know for sure is to try to read both with the multi meter and see which one lacks current.

I think there is current going to it because the light on my external hard drive turns on and it blinks, but nothing happens after that. It just doesn't turn on the way it's supposed to

And as you said above both keyboard and mouse also don't work when connected to those ports. There might be current, just not enough. The only way I know to figure it out is by reading with the multi meter.

Oh that's a good point, thank you for the suggestion! I would not have thought to do that. I'll have to get a multimeter and check that
