U.C manger / pc clean

Bonjour,

voila j'ai l'U.C de mon ordi qui se bouffe toute seul, j'ai fait plusieurs scan antivirus et antispyware différent et je n'es rien pus décelé, j'ai entendu parler de hijack et j'ai fait un rapport avec.
je n'es pas l'impression qu'il soit mauvais mais n'y connaissant rien, je préfères m'en remettre aux experts en vérole de ccm
je vous remerci d'avance pour l'aide que vous m'aporterais

martin
