Vista Ultimate STRESSED Out error codes, etc

So far my three days with Vista Ultimate on my new machine have been absolutely hellish. There are so many different types of blue screens, error codes, app crashes (Parts of Vista) I am totally lost.
Is there a site where I can enter info like the following, get the definition of what it means, and how to fix it? (I have tried searching but no good results yet):
