Impossible de charger direct3d ( league of legends )

Bonjour,
J'ai reçu un ordinateur d'un ami.
Il m'a fournit avec le pc le disque d'installation windows 7
J'ai donc installé windows 7 édition intégral
J'ai voulu ensuite jouer à League of Legends
Quand j'ai voulu lancer lol il m'a affiché impossible de charger direct3d
Apres avoir cherché la solution pendant plusieurs semaine j'ai pris la décision de poser la question sur ce forum
Dans dxdiag il n'y a pas de bouton activer à côté de direct3d

ma config est la suivante
