bonjour,
j'ai le probleme suivant sous xp, avant d'ouvrir la boite mail le processeur est occupe a 10% et lorsque j'ouvre ma boite mail je passe a 100% meme en la refermant et ce jusqu'a extinction du pc lorsque je le redemarre je retrouve une utilisation normale.
j'observe aussi que sur internet explorer les pages s'ouvre moins vite et que la barre sous la fenetre reste bleu.
 
j'ai verifie avec nod32 et avg anti spyware rien trouve.
le gestionnaire de tache est aussi tronque il ne reste que la barre de tache
 
merci de votre aide
