[explorer.exe] plante a chaque fois

Salut, voilà j'ai un gros problème avec l'explorer.
dès que je veux l'utiliser, il se ferme directement et fait planter le systeme ou bien il redemarre mais il est toujour impossible de l'ouvrir.
De plus il m'est impossible de lancer l'application nettoyage du disque.
Je suis pourtant sous windows xp sp2.
je ne sais plus quoi fais et je ne pense pas qu'une reinstallation va resoudre le probleme.
Alors que faire ?
merci

je rajoute hijackthis, si cela peut vous aider
