Problème de plantages

Bonjour, à tous.

Depuis plusieurs mois déjà j'ai un problème avec mon pc. En effet le nombre d'écrans bleus reste toujours le même malgré un formatage dans les règles de l'art il y a 3/4 mois. Dans ces fameux écrans bleus il me dit de changer de carte graphique seul hic même en prenant une carte graphique d'une autre marque les plantages sont toujours là.

J'ai même mis à jour les pilotes de ma GeForce 7600 GS de chez Nvidia mais les derniers pilotes n'arrange rien du tout car impossible de dépasser 4 bits et une résolution de 800 par 600.

Voici ce que donne une analyse d'un dump par windbg :
