Question USB Port Not Working

    Hello, I have a half year old Toshiba L740.

    Recently, one of my USB slots didn't work.

    I tried to search the posts that can help make the slot work again.

    It did work for a very short period of time ( like 10 minutes) when I re-started the laptop just for one time.

    Then, I tried to do "regedit" thing.

    When I clicked "HKEY_LOCAL_MACHINE\", the only thing listed there was "Default". I couldn't do anything further.

    Can anyone help me to solve this problem? 

    Thanks.
