I don't think anyone here is going to walk you through it step by step but if you have specific questions someone might answer them for you.
There are beginner overclocking guides here and other places. Google your cpu with the word overclocking behind it and see what turns up. Most likely there is an article about it floating around somewhere already.
Once you have a basic idea what is going on come on back and ask some more specific questions. If you read a few overclocking how to articles and are still completely lost you might want to re think trying to do it.
