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
downloaded from<br>

Latest LTS release: 12.04, Precise Pangolin (64bit Desktop)<br>

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>
