I just wanted to chime in, if you are running Windows 10, (I assume) powering down your PC everynight actually does not fully power down the machine, it places windows 10 is a very deep hibernation giving a false sense of shutdown so that when you power back on (wake up) Windows 10 boots quickly. Unless you turn this feature off (don't, things get weird) make sure you are rebooting once a week to free up system processes.
