While pressing start button in control panel it's showing some problem detected.
Looks like you've got a different version of MySQL already running. I assume that you've installed MySQL under XAMPP directory, but in order to run this port 3306 needs to be free. If a different version of mysql is already running, then this will block you from opening aa different version.
Remove the other install. BTW - remember to back up any dbs that you have first!
A simple test could be to open up cmd (Windows Key + R) and typing in services.msc then finding the MySQL service and stopping it, then starting it using XAMPP. Let me know how you go.
