How does a simple restart often fix computer issues and problems?

JOiseau

One of the first things tech support generally tells me if I have a problem is to restart my computer. That’s worked so many times that it’s helped me avoid a lot of unnecessary calls for help, but how can a simple restart fix a problem. If my car isn’t working, I can’t generally just restart it and then have it work fine. I sure wish I could, though! How does a restart actually fix anything on a computer?

I think it’s easy for people to forget how complex computers really are, and how many processes are going on at any given moment. To keep everything in RAM precisely the way it ideally should be is nearly impossible, and when a computer is left running for days it becomes even harder. By restarting, the user clears the RAM and starts with a fresh page that is cleared of whatever caused the problem and everything is ok again. Of course, should the problem (whatever it might be) occur again it indicates that it is more of a problem that something just getting “messed up” in memory, and the issue is going to need to be identified and rectified.

Why Does Rebooting a Computer Fix So Many Problems?
http://www.howtogeek.com/173760/htg-explains-why-does-rebooting-a-comput...

"Ask a geek how to fix a problem you’ve having with your Windows computer and they’ll likely ask “Have you tried rebooting it?” This seems like a flippant response, but rebooting a computer can actually solve many problems.

So what’s going on here? Why does resetting a device or restarting a program fix so many problems? And why don’t geeks try to identify and fix problems rather than use the blunt hammer of “reset it”?"
