say , I have windows 2000, and I went into my power settings and found only my monitor is set to go off at 20 minutes, The question , is my computer is very quiet without turning the hard drives off after say 30 minutes, when I had windows 98 ,I could actually hear the hard drives kick in , but not now so I stand by the old fraze if its not broke dont fix it, but is this ok to leave it on without the hard drives turning off? ?
