I know, most of us do not power down their desktop but just set the power management so that it sleeps when not in use. But if the desktop is used only for a few hours say in the evening and morning, would it make sense to power it down instead. This not from the point of view of power consumption, but from the overall life of all the components. or will it have adverse effect, e.g. the boot disk has to do the work of loading the OS at every start up and unloading at shutdown.. What do you guys think?
