Mon PC est d'une lenteur inimaginable !!!

Bonjour,

Je suis utilisateur de mon PC depuis l'année 2002. J'utilise Windows XP SERVICE PACK 2. Je suis actuellement victime d'une lenteur incroyable avec une serie de bugs assez énervants. J'ai essayé de me demander à quoi cette lenteur était due. Voici avant tout mon rapport HijackThis :
