UC à 100% et ordi très ralenti

Bonjour,
et bonne année à tous !

mon ordi est extrêmement ralenti et indique que l'UC utilisée est de 100%.
J'ai fait un Hijack This qui donne le rapport suivant, est-ce que quelqu'un pourrait m'aider à commencer l'année en beauté en accélérant un peu tout cela ?? Merci beaucoup à tous !
