DEPUIS UNE MISE A JOUR WINDOWS MON PC MET PLUS DE 5 MIN A DEMARRER

Bonjour,
Suite à une mise a jour windows update mon pc met plus de 5min a demarrer, en fait il se bloque sur un écran bleu marine pendant 4 min et apres il ya le logo vista qui apparait et il demarre enfin, par ailleurs il est tres lent aussi pour ouvrir un programme au debut du demarrage!
j'ai fait une defragmenation, j'ai desactivé les logiciels inutiles au demarrage, j'ai fait un antivirus, un antispy et la je ne sais plus quoi faire pour eviter une formation!!
Auriez vous une idée de mon problème?
je vous poste un rapport hijackthis ça peut aider me semble t'il
merci par avance de voter aide:
