Monitor went BLACK on Desktop, but not Laptop ?

My daughter's Desktop monitor went black.
She hooked it up to her laptop and it worked perfectly.

Tried to boot from install disk and got to Safe Mode but then
went black again.

Any idea's on to fix it. I assume since the monitor works
(with the laptop) it has something to do with XP.

The only things that was done was to add a new "external hard drive" which
was
done successfully, but when she went to try to assign her Norton backup to
store
on the new drive, Norton wouldn't let her. So she shut down for the night
and
work on it the next day.

Next day, boot up, and black screen.

Thank in advance for the help!

Does it generate any beeps ?
Does it "power up" as in power on lights on HP computer ?

The symptoms might not have anything to do with the Win XP
operating system.

The black screen is unlikely to be caused by a defective monitor,
because the monitor works OK with a different computer. However,
there could be a problem with the video card - or with other
hardware within the computer. At best, the problem might be
nothing more than a loose connection.

This may be a complete red herring. However, it will do no harm
to perform the following simple checks:

1. Check that the lead that connects the computer to the
monitor is firmly connected at both ends.

2. If that doesn't resolve the problem, disconnect the
computer from the power supply. Remove the part of the casing
that provides access to the internal components. If there is a
separate video card, remove it gently and reinsert it in its
socket. Check that there are no other loose connections. Also
check that all other cards are firmly seated in their sockets.
