Processeur en constante activité - plus de 20%

[acropole]

Bonjour,

Depuis que j'ai installé un dual boot avec win 7 64bits sur un disque dure t laissé xp 32bit sur l'autre, j'ai un des coeurs du proc qui est constamment en activité. Le gestionnaire des tache indique aux alentour de 20% d'utilisé même lorsque aucun processus ne tourne au dessus de 0%.
J'ai désinfecté ma machine avec AVG qui m'a trouvé et corrigé quelques truc, mais ça continu.

Voici le log hijackthis :
