No - It was split because your problem occurred after re-installing, kinda as stated in the new topic title.
As for your solution -
A. You should check the Window Services Manager to see if httpd.exe, Apache24 or mysqld are listed as services. If they are the should be removed.
B. Check in Control Panel > Programs and see if MySQL is installed (It should not be)
C. the proper way to remove/upgrade XAMPP is outlined in this postviewtopic.php?f=16&t=50988
Getting rid of any old installs is always the first step
