24/7 Baby! For those turner offers that fell like they'll be getting more life out of their parts with them physically off...relax...how about having window do it for you? Right click on you desktop, select properties, go to the screensavers tab and there under power and advanced you will find your little helper. Help with everything you're worried about wearing out including your hard drive and monitor. Maybe you even have a hibernation in case you have any shut off withdrawls...use this first... 😉
