$(document).ready(function(){
         var hash = window.location.hash;
      
     switch(hash){
        case '#video' : Change('1')
        break
        case '#music' : Change('2')
        break
        case '#games' : Change('3')
        break
        case '#converse' : Change('4')
        break
        case '#portal' : Change('5')
        break
        case '#servises' : Change('6')
        break
        case '#books' : Change('7')
        break
        case '#vkchat' : Change('8')
        break
   }
});

Можно проще:

$(function(){
     var a = window.location.hash, b = ['video', 'music', 'games', 'converse', 'portal', 'servises', 'books', 'vkchat'];
     for(i=0; i<b.length; i++) if(a == '#'+b[i]) Change(i+1);
});
