Usage du UC tjrs à 97%!

Bonjour,
J'ai un problème depuis quelque jours... Mon ordinateur roule toujours à 95-100 % sans que j'exécute des programmes demandants. J'ai installé dernièrement xFire (genre d'MSN pour gamers) et Hamachi.. Pourriez-vous analyser mon log HijackThis et me dire si quelque chose va mal? J'ai fait mes recherches et aucun autre forum ne me correspond.... MERCI!!!
