Disable Gameobject Via Script

I want to make my script to disable an object instead of destroy it, since destroying it seems to blow up console with errors.
Here is my script;

      function Start(){

Destroy (GameObject.FindWithTag("Player"));
GetComponent.<AudioSource>().pitch = Time.timeScale = 0.3;
yield WaitForSeconds (3);


Application.LoadLevel(0)



}

Problem is that i dont have any idea where to put “SetActive=False” there?

Try

     function Start(){
     
     (GameObject.FindWithTag("Player").SetActive(false));
     GetComponent.<AudioSource>().pitch = Time.timeScale = 0.3;
     yield WaitForSeconds (3);
     
     
     Application.LoadLevel(0)
     }
