Extinction inopinée de mon iMac

[js.bach]

Bonjour à tous,

D'un coup il y a quelques minutes, mon iMac 2011 m'a fait une frayeur. Ça faisait au moins dix ans que je n'avais pas vu ça sur un mac !

Voici ce que me donne le compte rendu d'erreur, après redémarrage angoissé de la machine. Quelqu'un pourrait me dire ce que ça veut dire ? Dois-je m'inquiéter d'une prochaine panne du disque dur ? des barrettes mémoires ?

D'avance merci...

Dans la mesure ou tu as ça "Possible memory corruption"

Tu peux enlever toutes tes barrettes et les remettre en place, ou les changer de place.

Des fois il suffit d'un rien pour avoir un soucis avec la Ram, et il suffit d'un rien pour le réparer…

[js.bach]

Merci beaucoup pour ta réponse !

Donc, a priori, ce serait bien les barrettes mémoires. je vais faire ce que tu suggères.

À bientôt !
