Hi. My usb ports on not working. Whenever I plug something into the usb ports nothing happens. But the weird thing is that when I starting up it does detect it but when the computer is done loading it doesn't. Any suggestions? Thanks.

For instance, what are you plugging in?

Did it work before?

Any changes that either happened or that you perhaps made to your computer around the time that the problem started; particularly any Software or Hardware that you installed or setup.

What OS?
