Is this a desktop or laptop? Do you plug usb devices into the front of the case?

Typically this problem is due to the USB port having a short. The plastic tab inside possibly broke off exposing the pins inside and they are bent inside touching one another, or shorting to the USB outside chassis grounding.

Disconnect the power and Inspect the ports both Female/Male ends. Bend the pins so they aren't shorting. If you cant bend them and it's a port on the front you can open the case and disconnect the usb cable connected to the front panel. If it's in the rear of the computer, you will have to try to bend them as the usb port is soldered directly to the board.

Did you find any damaged USB ports?

You may have to use something like this temporarily to troubleshoot the problem. Typically this is due to USB port dmg as the pins are shorting. However, it could be the USB hub malfunctioning, or moisture/cold, water etc. Do you live in a high humidity area like a coastal region? Do you have a water cooler by any chance? If you do check that for leakage. Check inside the case for signs of moisture.

By the sound of it something is shorting out and causing that damge to the motherboard. Things like that again might be caused by moisture/corrosion, a short in USB port or device plugged in, front panel usb/phono/mic, or wires pinched shorting out. It's possible that the component just failed on it's own. A resistor can blow and still allow full current flow thus overvolting it. However, a short somewhere else in the system can also cause the resistor to get to hot and blow. Then you got two problems a short and a resistor failing to control current flow.

Yes, you need to take it to local computer repair shop. Good luck.
