Bsod à cause d'un driver Nvidia

Bonjour,

Voilà, j'ai un gros soucis de Crash avec écran bleu sous certaines applications (jeux vidéos en général)

En regardant dans le journal d'évènement j'ai cru comprendre que ça venait d'un driver qui entrait en conflit (erreur "Kernel Power"), puis suite à des recherches, j'ai fait une analyse des mes Dump avec Whocrashed (voir ci dessous) qui m'a montrer deux type d'erreur, concernant deux drivers d'Nvidia.

Nvidia ne me propose pas de mise à jour.

Par ailleurs, si je veux utiliser Ntune, le Pc plante et j'ai un bluescreen.
