Problem
Pick a peripheral/ancillary device that is attached to your PC and tell us all about it.
Maybe the mouse? The printer? The monitor (if you have one)? The camera (built-in or attached)? The CD-tray (if your PC still has one)? A USB-attached device (hub? CD-tray? headphones?)?
What brand/model is it? How does it work? What are its features?
