I have yet another propblem with my new computer running Vista Home Premium. I noticed that I set up my screen saver to be a certain screen. I set the time for 5 minutes. I have never seen this come on yet. I have left the computer sitting there for hours and the screen never changes. I set the time for 1 minute and nothing happens. My old monitor would go into sleep mode but this one does nothing. I tried changing the power settings and nothing happens there either. I have had nothing but problems with this system since I got it. I never had trouble with XP. Is this a function of my monitor (HPw2207h) or Windows????
