Utilisation CPU 80%-100% en permanence

Bonjour,

Possesseur d'un AMD 3000+ sur 939, je suis depuis quelques jours en quête d'une solution pour libérer les ressources de mon système. En effet, le CPU est utilisé en 80 et 100% sans qu'aucun programme ne tourne.

J'ai désinstallé SpyWare Doctor 5.0 qui prenait lui aussi des ressources et lancé une analyse complète avec l'utilitaire Windows Live OneCare ainsi qu'avec Spybot.

Si quelqu'un pouvait m'aider, ce serait avec grand plaisir.

J'ai copier si dessous le résultat de HighJacThis:
