Video Problems

This morning my computer displayed the following problems:

Screen areas that should be white are now gray.  Streaky hortizontal darker gray areas than others and when cursor is dragged up and down the screen a darker gray area follows along with it.  Colors are showing up almost neon-like.  I have a Samsung 204B LCD moinitor which I have hooked up to another computer and is working properly.  Here are the specs of my Dimension 8100:
