Disque dur bruit byzarre

Bonjour,

Mon pc a 3 mois et mon disque dur de temps en temps fait un petit bruit et j ai de gros ralatissement. Depuis lundi il ne la pas fait et ce matin il recommence un bruit toutes les 20 s ou tous les 15 mn cela varie et plus rien. J ai fait un test avec crystaldiskinfo mais pour moi c'est du chinois. Le DD est garantie il me propose de l envoyer par la poste et de voir le probleme et si probleme me le changer mais dans ce cas la j irais acheter un autre pour ne pas perdre toutes mes donnees.
Ma question mon DD est il mort ?
merci d avance
