So is it better to leave your PC running all day, or do you turn it off and on? If you leave it on: Do you leave it in Sleep Mode, or Hybernate, or just let it run the whole time? I have a laptop, and I was just curious, cuz sometimes i'll leave it running the whole night, i just turn off the monitor. Most of the time I leave it in Sleep Mode through the night. So what do yall do?
