Depuis quelques jours, j'ai , dès le démarrage de mon PC, le processus "SYSTEM" qui prends 100% des resources.
 
Voilà ce que j'ai fait déjà pour essayer de résoudre le problème:
 
-restaurer mon PC à 2 jours, 1 semaine, 1 mois ulterieur. Rien
-Passer plusieurs antivirus. (avast, adaware, MS defender). Rien
-démarrer le système sans AUCUn option spécifié dans msconfig (pas de win.ini, pas de services, rien). Rien
-résinstaller windows (sur l'ancien). Rien
-passer testor (Décrit dans un autre thread ici). Rien
 
Bref, je commence à etre en court d'idée. Dès que je démarre le système, l'UC est à 100% , pris par le processus SYSTEM et ça reste comme ça.  
La seul façon ou ça s'arrete , est quand je démarre le système en mode sans échec.
 
Quelqu'un a un idée???
 
Merci

Problème résolu. Mais c'est la plus étrange solution que j'ai jamais utilisé.....  
 
Ceci fonctionne sur un PC HP. Je ne sais pas si ça fonctionne sur d'autres
 
-éteindre le PC
-débrancher le cable d'alimentation
-appyer sur le bouton de démarrage et rester appyer pendant 3 minutes
-en restant appuyez sur le bouton demarrer, rebrancher le cable d'alimentation
le PC démarre.
 
maintenant plus d'UC à 100%
 
reste le problème: quand je le ferme, l'affichage "Fermeture de windows" reste affiché. Normalement le PC s'étent tout seul, mais là, il faut que j'appuye sur le bouton de démarrage pour l'arreter....

copy ton log sur ce site : http://www.hijackthis.de/ c'est plus rapide que d'attendre qu'on te dise que fixer.
