Should I turn off my PC at night?
At the end of the day, what to do?
TURN IT OFF? Risk wearing out your hard drive prematurely.
LEAVE IT ON? Electricity costs about $1/day for PC & monitor running 24 hours/day. Turn it off at night, and save about $120/year! CRT (cathode-ray tube) monitors account for 2/3 of that energy. LCD (liquid-crystal display) monitors require ½ the energy of a CRT monitor.
THE ANSWER: It all depends. You can set your system to automatically shut down your monitor after 15 minutes of inactivity and shut down your PC only if you are leaving for an extended period of time (e.g more than a day).
