Juanita, In the old days, it was wise to leave computers on all the time because the wear and tear on re-starting hard drives was very damaging to those devices. However, in modern PCs that is no longer the case. I was one of those that left my PC on for weeks at a time without rebooting or shutting down. However, I now turn my machine off at night. This saves money in wasted energy and preserves your PC components by minimizing the effect of heat and dust build-up. -= Victor =- From: triadtechtalk-bounce@xxxxxxxxxxxxx [mailto:triadtechtalk-bounce@xxxxxxxxxxxxx] On Behalf Of Juanita Kimble Sent: Friday, March 20, 2009 9:50 PM To: triadtechtalk@xxxxxxxxxxxxx Subject: [triadtechtalk] Computer running Hi everyone! If you let you computer running all the time. How often should you reboot? How long will your fan last? How many of you let yours run all the time. What do you gain by letting it run all the time? What do you gain by turning it off when you are through for the day? Juanita
