I've been working in IT for over 20 years. I've had PCs going all the way back to the mid-90's. In all of those years, I have NEVER had to turn my PC off nightly. People have problems because (a) electronics fail, (b) people don't know much about what they are working with, and (c) they listen to advice from people like you who don't know what they are talking about. In a professional setting, we don't shut down PCs or servers EVER. They get rebooted periodically for maintenance, but we don't shut them down for long periods of time unless they are getting moved or replaced.

Agreed, its hard for employees to remote into their work pc when it is off. When i worked in IT everyone logged out at the end of the day and back in the next morning. 

Usually they wouldn't get rebooted until the user called in with issues, resulting in the obvious question...have you rebooted lately.
