Bug ? coupure soudaine

Bonjour,


Voici mon soucis:
On vient de me donner un portable qui marche a priori pas trop mal sauf qu'il s'etaint de facon soudaine lorsque je visionne des videos ou a télé.
Je pensais que cela venait d'un manque de mémoire vive alors j'ai viré pas mal de fichers, pour libérer de l'espace.
Mais le problème persiste. Apparamment il ne le faisait pas avant que je ne l ai.
