BlueScreen IRQL_NOT_LESS_OR_EQUAL

Bonjour,

Depuis peu une erreur de bluescreen m'est apparue ,j'essaye tant bien que mal de réparer ce problème mais le bluescreen apparaît quand même .
J'ai vu sur le forum que c'était peut-être du à un pilote de ma carte graphique(en passant elle est très merdique) qui n'était pas a jour alors que cela a été fait il n'y a même pas hier.
J'ai aussi recherché sur le net et j'ai téléchargé WhoCrashed et voila ce qu'il y a marqué :
