Bonjour, je possède un iMac (24 pouces, début 2009 Intel Core 2 Duo, GT 130) qui depuis pas mal de temps n'arrete pas de s'éteindre après un certain temps après le démarrage, sous Snow Leopard cela prend quelques minutes jsuqu'à High Sierra ou je n'ai pas le temps de me connecter. le problème n'apparait pas en mode sans échec, j'imagine que cela vient donc d'un driver qui fait crasher le pc, et peut etre aussi d'un composant. 
J'ai déjà augmenter la ram qui est de 4 Go de base à 8 Go, dépoussiérer, changer la pate thermique.
Voici les logs à 09:32:57,925 ou le crash ce produit:
