If Apache is the service that is not running it is normally, but not always, because something else has captured port 80.
Now do, Left click the wampmanager icon to reveal the menu-> Apache -> Service -> Test port 80 This will launch a command window and display some information about what, if anything is using port 80.
Whatever it is should be re-configured to not use port 80 or uninstalled if you are not using it.
If port 80 is not the problem look for errors in the appropriate error log ( use the wamp manager menus to view the error logs )
If these do not exists or show no errors then also check the Windows Event Viewer Start -> Administrative Tools -> Event Viewer And look in the 'Windows Logs' -> Application' section accessed from the menu on the left of the dialog for error messages from Apache and or MySQL.
