Mon ordi rame complétement

Bonjour,

Mon ordinateur windows XP pentium 4 rame à fond. Pour tout dire je mets entre 3 et 15 minutes à ouvrir une page internet, c'est tellement lent que je dois même attendre et vérifier que les lettres s'inscrivent bien quand j'écris un message. Il n'y a pas que internet qui rame mais tout mes logiciels aussi. Pourtant la mémoire n'est qu'à moitié pleine et je n'ais à prioris pas de virus où en tout cas mes deux anti-virus norton (la nouvelle version) et avast ne les détectent pas.
Je nettoies aussi régulèrement mon disque.

J'ai regardé quelques autres topics de personnes qui ont à peu près les mêmes difficultées que moi et j'ai fais un scan avec hijackthis ce qui m'a donné ceci:

Est-ce que quelqu'un qui s'y connait pourrait me dire ce que je pourrais supprimer pour régler mon problème? Etant moi-même relativement novice, j'ai un peu peur de faire une bêtise et d'effacer n'importe quoi.

Sinon, si quelqu'un pourrait me donner d'autres conseils pour refaire marcher mon pc correctement, je sui preneuse!
Merci d'avance!
