It was a problem with the CD button on my mid tower case. When I press the
CD button on the outside of my case, it must move ever so slightly in order
to contact another button on the actual CD unit inside the case. We must
have been pressing it too hard, because it was slightly out of line,
causing it to be in almost constant contact with the button on the CD unit.
This was causing the CD drawer to eject randomly.
The fix is to remove the front bezel. (This requires removal of side
panels first. Unplug unit and follow all necessary static precautions.)
Examine the CD button attached to the front bezel. Make sure it is lined
up straight. It is basically a plastic tab. Ours was pushed slightly
upward. Reattach the front bezel and side panels.
Re: white background, go to the appearance tab in display properties and choose your colour scheme. IE, right click desktop and hit properties.
