Making my button clickable

I have a test page here:

http://www.accessdatabaserepair.com/index2.html

The 3 boxes at the top are all one graphic. I want to make the Start button clickable and also if I hover over it, it will change in some way.

What is the best way to do this?

Thanks,

Jon

 

First, you will need to separate it from the rest. Therefore, you can't just have 1 big image. As for the rollover, take a look at:
