WampServer

I have installed MySQL 5.6 on Window7 32 bits. I just installed Wampserver 2.4 32bits. I ran tests using Android PhPApp. Wampserver worked fine. But I am not sure if Wampserver is using my old MySQL files or the newly created files using phpmyadmin.

I have MySQL installed on my Window7. Now I install WampServer on top. Do I need to uninstall previously installed MySQL? If not, does WampServer connect to the old one or it has its own MySQL? It seems that WamServer is copying database from pre-installed MySQL. Which one has overriding create function? Please provide answers. Thanks.
