Mémoire à 1% de fonctionnement....

oh secours....
Mon ordinateur rame, j'ai plus de mémoire, alors que le disque dur est bon....
PLUS OUVRIR MSN.5 jours je ne pouvais même plus ouvrir MSN.

J'ai récupéré en partie grace à RAM BOOST XP.

Mais parfois je n'ai que 1% de mémoire...apparemment c'est le "cache système".
J'ai scanné avec pleins d'antivirus, antimalwares, sans rien trouver. Alors que c'est venu d'un coup depuis mercredi.

voila les rapports que j'ai eu en faisant l'antispyware, l'antivius et aussi l'antimalware
