Bonjour,
 
Depuis un certain temps mon pc s’arrête et redémarre inopinément. Mon disque dur a fini par rendre l'ame il y a quelques jours. J'en ai donc remis un neuf et fait une réinstallation de Win7. Cela n'a pas résolu mon problème de bluescreen.
Voici le rapport de Window:

Read the topic general suggestions for troubleshooting system crashes for more information.  
 
Note that it's not always possible to state with certainty whether a reported driver is actually responsible for crashing your system or that the root cause is in another module. Nonetheless it's suggested you look for updates for the products that these drivers belong to and regularly visit Windows update or enable automatic updates for Windows. In case a piece of malfunctioning hardware is causing trouble, a search with Google on the bug check errors together with the model name and brand of your computer may help you investigate this further.  
 
J'ai fait un test avec Memtest et il n'a rien trouvé.
