Salut à tous,

Voilà, tout est dans le titre - mon iMac Intel (sous Tiger 10.4.11) redémarre tout seul, sans aucune demande de ma part... Ca peut arriver quand je ne suis pas à coté ou quand je travaille dessus, peu importe, parfois je reviens après quelques minutes d'absence et je vois l'écran d'ouverture de la session - il a à nouveau décidé de redémarrer.
C'est franchement flippant, sans parler des emm... quand le travail n'est pas sauvegardé!

Pourriez-vous m'aider à résoudre ce problème, svp? Je ne comprends plus rien... Voici l'extrait de system.log d'aujourd'hui avec les heures concernées:

[Rico0o]

Le même soucis avec un ordi portable reboot aléatoire ou extinction franche ---> barette de RAM défectueuse dans mon cas

[C@cTuS]

Oui mais là il s agit d un Imac Intel , qui je suppose , est un Alu avec numero de serie qui se finit par X85 (20")/ X86 (20")/ ou X89 (24") ?

Dans ce cas là j peux te dire ce qui ne va pas

[CatFauve]

Et bien, non, c'est pas un Alu, c'est un 20" 2.16 GHz acheté début 2007.
Je capte pas... J'ai passé un coup de brosse OnyX, réparations des autorisations etc. et je l'ai laissé éteint pour la nuit (ce que je ne fais jamais, normalement il reste allumé en permanence). Pour l'instant ça va, mais pour combien de temps? Hier il a redémarré deux fois en l'espace de deux heures...
Je vais voir du coté des barrettes de RAM quand-même, merci pour l'info Rico0o.
