PC lent sans raison

Bonjour,

Je suis un fervant adepte de ce site et j'ai toujours trouvé la solution à mon problème ici. Cependant là j'ai un problème qui ne semble pas etre commun. En effet lorsque j'arrete le programme svchost qui prend 22Mo de mémoire ca fait sauter la carte audio du PC. Est ce normal ?

De plus, je pense que j'ai des spyware qui ne sont pas reconnu par ad-aware et spybot. Est il possible de me commenter mon hijackthis ?
