I have a dell 2100 running windows xp home edition.  I was running my anti spyware (webroot spy sweeper) and checking email.  There was no hint of a problem, simply the screen changed to this blue shade.  Everything else about the computer seems to be working fine.  Do you think it might be a monitor problem.  I have a viewsonic flatscreen which is about 2-3 years old?  Thank you.
