Sony Vaio VPCCA USB 3.0 Port Stopped Working!

Recently the USB 3.0 port on my Sony Vaio VPCCA/CB Series laptop has stopped working. I did notice that it came up with a message whilst I was using a USB soundcard saying that there had been a "power surge" on the port and it was since then when the trouble started.

I have tried uninstalling and reinstalling the drivers to no avail and I'm guessing that the port is dead.

Any ideas on how to fix this? Is it possible to fit a new USB port or are they not replaceable?
