Des problèmes graphiques et des gels - quelqu'un peut-il donner un sens à cette panique du noyau ?

J'ai eu des problèmes avec problèmes graphiques bizarres sur mon Macbook Pro 2011. Au service après-vente, ils ont conclu qu'il s'agissait d'un problème logiciel et non matériel. J'ai formaté mon SSD et réinstallé Lion (puisque c'est ce que l'outil de récupération m'a donné, même si j'avais Mountain Lion auparavant). Cela a fonctionné pendant une semaine, mais maintenant les problèmes se répètent à nouveau. J'ai réussi à obtenir un journal de panique du noyau cette fois-ci. Quelqu'un peut-il y comprendre quelque chose ?

Les problèmes me rendent parfois incapable de démarrer, même sur ma partition Windows, jusqu'à ce que je réinitialise la PRAM. J'ai vraiment peur que cela signifie qu'il s'agit bien d'un problème matériel.
