Why did you disconnected the USB ports on the laptop and how to solve this problem?

All welcome.
Tonight I sat working at the laptop, everything worked properly. Wake up in the morning, turn on the laptop and discover that there is one USB port doesn't work. I have connected the mouse + external hard drive, poking into all 3 ports, none works. Looked in the BIOS ports are not detected when connected to the devices.
All the tips and articles read:
1. For the viruses Cureit and AVZ cleaned (you never know, something with the driver on controlers did)
2. Switched on and off the USB controllers in device Manager
3. Cut down the power and pressed the power button for 10 seconds (sometimes it helps, in the case of statics)
All the controllers in the dispatcher displays work without conflict. Just the ports don't respond to the connection.
Talking business in the southern bridge, but on the laptop if I lost the southern bridge would not work anything else, touchpad or webcam, they are working properly. With my laptop cost carefully, so that overheating it is not present, did not fall never, nothing spilled on it. He just stands on the table, and I just work for him.
