Prob avec media center receiver service

Bonjour, depuis peu de temps je recois un rapport d'erreur toutes les 20 secondes. Il me dit que: Media Center Receiver Service a rencontré un problème et doit fermer. Nous vous prions de nous excuser pour le désagrément encouru.

J'ai remarqué aussi que lorsque je lance le gestionnaire de taches, dans l'onglet performances, la courbe effectue des pics touts les 10 secondes, utilisant jusqu'a 50% de la mémoire sans qu'aucune application soit en marche.

J'ai fait un log avec hijackthis:
