[Portable] pb de lenteur ap démarrage

Bonjour,
mon ami a un portable qui a des lenteurs voir des blocages de + de 10 secondes sans vraiment de logique. Cela peut arriver en écoutant de la musique ou en consultant la messagerie, en travaillant sur Illustrator ou word...
On a déjà passer Ad Aware et Spybot et rien ne se révèle être méchant.
+ a priori, il n'y a pas 2 antivirus + il a de la mémoire vive suffisante, de la place sur le disque dur.
Je vous joins une partie du rapport d'Everest puis le log de Hijackthis :
Pouvez-vous nous aider??

merci d'avance!!
