Ordinateur plante, ecran noir, ...

Bonjour,

J'ai un ordinateur qui plante de plus en plus régulièrement (ecran noir, freez de l'écran, blocage souris, ...). Derrière obligé de faire un hard reboot. Je viens de faire un rapport Hijack, je le copie après, si quelqu'un peut me donner un coup de main!

Merci beaucoup.
