got anything magnetic near the monitor as in speakers etc. Usually this
causes a green "theme". Can you change it in display? Since I don't know
how savvy you are, go to control panel_ display_ appearance_ click
advanced, hit the pulldown arrow, find windows, i believe or desktop. can't
remember although i reset my stuff once or twice a week just for fun. find
whatever one has a pink background if any and change it. Or it could be that
your monitor is losing a gun. Beyond that, wait for one of this forums
MVP's to sidle by your question and give expert advice.
