"Considering problems of creep..."
Yeah, I call my PC a creep from time to time........
What works for
me, I leave my PC's on 24/7. Unless I need to reboot. Or a tornado is predicted to come through the area.
This discussion has been done many times on many boards, with brilliant minds never coming to agreement. A lot depends on a lot of things......bottom line being try both methods, and see which you (or your computer) like best.
