Hi
Something that I've been told and excepted as fact, though I don't really know that it's true is that you actually get a cleaner restart by selecting "Restart" as opposed to shutting your computer off and turning it on again.
I believe that the process does not retain settings and open applications that turning your computer off does.
I've always used Restart when I wanted to clear my computer, maybe I should do some research and see if thats true.
Or maybe someone here knows?
Mike
