Pantallazos Azules (BSoD): ¿Alguien puede ayudarme?

Saludos, antes de nada aprovecho para saludar a la comunidad, acabo de entrar.

El problema es el siguiente:
Hace poco formateé mi PC y reinstalé Windows 7 x64, aparentemente sin ningún problema (drivers, programas que suelo usar, etc.). Sin embargo últimamente, sobretodo mientras juego a ciertos juegos que tiran bien de gráfica (lo cual me tiene un poco con la mosca detrás de la oreja....), me saltan pantallazos azules (BSoD).

Dejo aquí la información relativa a las BSoD que he tenido, a ver si alguien pudiese sacar información precisa de qué le ocurre a mi PC, muchas gracias.
