Mémoire UC saturée, mauvais son ..

Bonjour,

J'ai un Eee top de chez Asus.
Tout aller bien et du jour au lendemain, il s'est mis à démarrer très lentement, le son est très mauvais et la mémoire UC a des pics de saturation très régulièrement. J'ai noté que cela affecté le son quand j'écoute de la musique ou regarde une vidéo.. mais cela ne le fait pas en permanance. et ca ralenti tout le reste... es ce la carte son ? un virus ? un sur-chauffage ?

Merci pour votre aide !!!
