Ordinateur lente

Bonjour,

Normalement, je suis assez doué en informatique, mais la j'ai presque tout essayer... J'ai formaté deux fois, ca n'a rien changé. J'utilise Eset Smart Security (mis à jour au 30 minutes) et j'ai fais tout les updates de microsoft.

J'ai un disque (Disque D:, partition de 111Go) qui est corrompu... Quand je clique il affiche "D:\ is not accessible. The file or directory is corrupted and unreadable.", j'ai essayer un CHKDSK D: \B sans résultat, car il affiche dans msdos que le "fichier ou le dossier est introuvable". C'est plus ou moins récent.

Mon ordinateur travail presque sans arret et a tout les 5 minutes elle gêle pendant... 45 secondes.

Je suis connecté en Wifi sur un réseau nommé "Gary Haran's Network", non sécurisé... Y'en a partout des réseaux comme sa dans ma ville...

Je viens d'essayer de faire une autre mise a jour de microsoft et sa a donné : Erreurs trouvés : Code erreur 8024200D, 80070002 et erreur E0434F4D...
