AlexB's posts are excellent, just wanted to add these:
Event Viewer logs can be filled with useless information but also include
warnings that your system might get unstable...and if you don't look into
these warnings your system could be unstable or even crash.
There is different entires, information is usually not so interesting, but
you have warnings and critical errors and those you should look up.
If you manage more than one Vista machine you can subscribe event and have
one as a master machine and forward specific entries from other machines into
your master machine, I wrote an article about that here:
