One thing that is useful and (even I am guilty of) not used or looked at or talked about very much is Reliability Monitor..... It is something I have used many times in Vista,, and have neglected or not thought of having others use to see what might be causing some of their problems. If you go into Control Panel / Action Center / Maintenance / View Reliability History It can give you some indication of what might be causing some issues. Some things might possibly be ignorable, much like Event Viewer, but it can give a bit better information than Event Viewer. And it is easier to navigate and understand than event viewer. So I encourage people to check this tool and use it as a resource for troubleshooting. It is what it is there for.
