Remove title and edit box from Edit Post screen

You could use custom post types and totally design your own edit screen. The Plugin Custom Post Type UI does all that and gives you the opportunity to decide whether you want the editor on the edit page.

Try this,
Paste this code in your functions.php

function remove_box()
{
	 remove_post_type_support('post', 'title');
         remove_post_type_support('post', 'editor');
}
add_action("admin_init", "remove_box");
