Pc Fortement ralentit depuis peu

Bonjour,

Depuis quelques temps j'ai l'impression que mon pc galère, rien que pour afficher les icones quand j'ouvre un dossier. Je n'ai a priori pas de virus ou de trojan ni de probleme de pub intempestives.
J'ai fait un scan avec Hijackthis mais je dois dire que je n'y connais pas grand chose et j'espere que vous allez pouvoir m'aider :p
