Directx pas de son et pas de mélangeur

Bonjour,
j'ai un gros probleme que personne n'a pu le résoudre
j'ai formaté mon pc maintenant j'ai pas de son et j'ai istallé beaucoup de pilotes jusqu'à ce que je n'ai plus de "?" dans le gestionnaire, je n'ai pas de mélangeur de son et quand j'ouvre Virtual Dj il me di que le directx est introuvable...
j'ai dezipé directx9.0b et je fais un dxdiag et je trouve beuacoup de "not run"
