          I recently purchased a branded Dell Optiplex 3020 Desktop that
          shipped with ubuntu. I removed the ubuntu installed in it and
          installed Xubuntu 64bit in this Desktop through the torrent

          I encounter a problem whenever I shutdown or restart;  the
          screen goes black, my computer doesn't power off. The fans
          still run and the screen is still on, etc. I have to hold down
          the power button in order to completly shut down.<br>

    Have you checked your shutdown sequence. My experience is a process
    fails to shutdown thus creating a hang during the shutdown sequence
    preventing the final signal for power-off from being triggered. 
    Unfortunately your screen blanks.  Try switching to a terminal from
    GUI:<br>
    <br>
    ctrl+alt=F[1-5]<br>
    <br>
    #login:[username]<br>
    #[enter password]<br>
    <br>
    from here issue the shutdown command manually:<br>
    <br>
    # shutdown -h now<br>
    <br>
    You may need to sudo the shutdown command.<br>
    <br>
    hopefully this will allow you to see the shutdown sequence and where
    the system may be hanging.  Once identified the community should be
    able to help move things along.<br>
    <br>
    HTH<br>
