Irql not less or equal

Bonjour, depuis deux trois jours, j'ai un probleme assez .. génant avec mon ordinateur =/

Apres la selection des utilisateurs, l'ecran devien bleu et affiche:
IRQL NOT LESS OR EQUAL

J'ai lancé un scan hijackthis et voici le resultat:

Par ailleurs, je peut utiliser mon ordinateur par intermittence entre deux "blue screen of the death", mais je ne peut
pas lancer mon gestionnaire des tache, ni regedit, ni idpconfig etc ..

Mon CD d'installation semble bugger lui aussi, étant SP1 alors que j'utilise SP3
.. info flash, mon ordinateur ayant decidé de me laisser me connecter m'a fait un arret systeme a cause de service.exe .. si ça peut aider
