Are you plugging it into a USB hub? If so, try plugging the USB cable from the Arduino directly to one of the USB ports on the PC motherboard.

Have you ever been able to connect it to the PC? Is this the first time it has happened?

Have you tried re-starting the PC? I mean power--re-start, not power OFF, power ON?
The restart process can help clean up some junk.
Also, after that, try connecting the Arduino to the PC before powering up the PC
