Quick question: What's the best mode to use when I don't need my computer? I use the pc everday and I've heard it's bad to shut it off and turn it on each time but when I put it in sleep mode, I still here fans and things working inside. To me, that seems like wasted hours on the pc's normal wear and tear. Right now I let it run all day long and shut down before I go to bed, but should I hibernate it or something instead? What's the best for extending my computer's lifetime? Thanks in advance.
