Ordinateur très lent depuis peu de temps

Bonjour,

<config>Windows XP
depuis à peu près 1 semaine mon ordinateur est très lent surtout sur des sites comme megavideo, youtube ou encore deezer!
Il rame également enormement sur itunes (au niveau du son) et souvent quand je bouge ma souris elle met du temps à reagir et disparais pendant quelques seconde.
