Demande d'étude de log...mon ordi rame

Bien le bonjour à toutes et tous,

ma bécane rame un peu ces temps derniers, surtout pour ouvrir les programmes (netscape, winamp,...). Je pense avoir quelques problèmes mais j'ai du mal à identifier lesquels (256 Mo seulement de mémoire vive en étant déjà un...)

je vous laisse le dernier log que j'ai fait avec Hijackthis...si j'peux vavoir votre avis...
