PC de plus en plus lent

Bonjour,

Me semble que mon PC ralenti de plus en plus, suite surement à des processus qui surchargent mon unité centrale ?

J'ai 4Go de Ram, un processus 2*2.4Ghz, c'est pas très normal non ?

Je tourne sous windows xp, est-ce qu'il arrive à encaisser les 4 gigas de ram ? si oui comment ?

Un rapport hijackthis.
