Blue screen en jeux

Bonjour, hier j'ai eu un blue screen et je vient encore d'en avoir un aujourd'hui, ça se passe toujours en jeu, hier a bf3 aujourd'hui a sleeping dogs, j'ai déjà désinstallé les drivers de ma cg, utilisé driver fusion et réinstallé mais j'ai encore le même pronlème, est ce que ça peut être un problème matériel? Et je peut jouer sans risque ? Voila le rapport de WhoCrashed :
