Yes, turn it off. I also agree that computers should be turned off when you are "done" for the day. I have aquantainces that do not ever turn them off. Their computers never seem to last a long. My last computer at the office lasted over six years and was fine until space on the HD and memory became an issue. My last Home Computer was almost a teenager before it was replaced. If fact I just recently gave away my old Packard-Bell computer (Windows 95) and it still worked! I do still have my Heath-Zenith (Cost $ 3000.00 new! With Zenith-DOS.) -Have a good vacation!
