Defragmentation impossible

bonjour,merci a tous pour les réponses à mon probleme
mais je n'arrive toujours pas à effectuer une défrag de mon disque dur
j'ai essayé toutes les solutions,cc cleaner,avg,spibot,anti virus en ligne,hijakthis..et autres.chkdsk ne trouve rien,pas d'erreurs.
il m'est aussi toujours impossible de lancer internet explorer,ni de recevoir mes messages sur outloock..
si quelqu'un a une solution à me proposer,je le remercie d'avance
je joint ici un rapport hijakthis,pour une éventuelle analyse..
merci ,
