I never shut down my desktop computer so it's always running. Though most times, I will turn the screen off. And, there is a screensaver. I have not rebooted in over a week. I don't know if this is good for the computer, but it's so much of a hassle to get all my software and tabs back up where I want them. For my laptop, I turn it off at least once a day until it cools off. What about you?
