Driver-irql-not-less-or-equal memory manageme

Bonjour,

Depuis quelques temps, j'ai un écran bleu clair à l'ouverture de windows. De plus, je ne peux plus exécuter ou supprimer certains logiciels ou en actualiser d'autres. Seul Spybot semble fonctionner normalement.
Merci d'avance pour votre aide.

Je vous envoie le rapport hijackthis:
