PC qui rame/lag soudainement

Salut.

J'espère que je suis dans le bonne partie. Depuis quelque temps, mon PC rame comme un porc, aussi bien pour les téléchargements que pour les jeux, les ouvertures de dossier et internet.

Mais en tant que nolife, ce qui me dérange c'est sur Call of duty 5. Avant je le faisais tourner sans aucun problème, aussi bien pour le solo que le multi, mais là même en solo c'est injouable.

J'ai PU faire tourner ce jeu avec les graphismes au maximum avant, alors pourquoi cette baisse?

Je passe régulièrement un coup de CCleaner, parfois un autre petit coup d'AVG anti-spyware.

J'ai encore 159Go de libre sur mon disque dur, d'après un speedtest j'ai ça : https://www.speedtest.net/result/676895061.png

J'ajoute qu'il n'y a aucun processus qui bouffe toute ma RAM, et au passage, il me semble avoir une RAM de 2Go.

Je suis sur windows XP.

Je donne ma configuration, et au cas où, un scan HijackThis :
