Bonjour,

j'ai un imac 24 de 2009 et depuis le 11 février, il plante régulièrement avec un écran figé, aucun autre moyen que d'éteindre sauvagement la bête. Après le redémarrage j'ai un kernel panic. Je pense à un problème de carte graphique mais sans aucun certitude.

Pouvez-vous m'aider à décoder les deux kp suivants ?

Merci à ceux qui peuvent me renseigner

Bonjour,

Tous les messages font penser à un pb de carte graphique.
Après, avec les KP, il y a deux choses à tenter rapidement :
  1. enlever la RAM ajoutée après l'achat (remettre en configuration Apple) et voir s'il y a toujours des KP;
  2. lancer un Apple Hardware Test (qui est loin de tout diagnostiquer, mais c'est déjà une première chose à faire).
