Monitors, on the other hand, seem to like to be shut off regularly. At work, we bought 9 Nanao F750's & &60's in 1993. Only two survive, and one sits on my desk and is turned on and off daily. Those that were left on 24/7 did not survive the last cycle of cpu upgrades. Ken At 01:42 AM 4/19/200

All this talk about PC's running 24/7 has convinced me of the reliability of processors. It's been my thoughts that if your computer is on, it's always running at full speed, whether or not you're running Prime95. I've always left my computers on all the time, and never had a problem. This rel
