HD3850 et processeur à 100% en permanence

Bonjour,

Je viens de recevoir mon PC du SAV de materiel.net avec la nouvelle HD3850 de chez Connect3D, et le processeur est utilisé a 100% en permanence.

Il est impossible de jouer et la navigation sur windows devient parfois.... fatiguante...

Aidez-moi s'il vous plait, j'ai mis à jour windows et les drivers ati, rien ne changent.

Ici, un aperçu de mon malheur : http://img99.imageshack.us/img99/8015/tasklc7.jpg
