Je suis nouveau ici et ma venu dans ce forum est le fruit de mon ordinateur portable qui s'est amusé à me montrer un magnifique écran bleu, le fameux BlueScreen of the Death!!!

Il est survenu une fois, je me suis dis rien de bien méchant car aucune récidive depuis quelques mois! Cependant, le voilà de retour depuis quelques jours et de manière plus régulière (3 fois en moins d'une semaine).
J'ai quelques notions en informatique et trouve toujours le moyen de bidouiller l'ordinateur grâce à mon sens logique et quelques recherche sur internet. Mais là je me bats face au coté obscur de la bête et cela dépasse mes connaissance en la matière! Je viens donc vers vous pour m'aider à trouver la source du problème et le résoudre (et par la même occasion m'instruire sur la chose pour y faire face seul si cela venait à se reproduire)
Après quelques recherche sur le net voici en j'en suis arrivé: le résultat d'analyse du logiciel Whocrashed,

It is strongly suggested that you check for updates for these drivers on their company websites. Click on the links below to search with Google for updates for these drivers:

This often yields interesting results from discussions from users who have been experiencing similar problems.
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 fais une mise à jour du logiciel Avast en espérant que cela soit la solution... Pour l'heure je ne peux pas m'aventurer et dire que le problème est résolu.
EDIT: J'ai lu que le firewall ZoneAlarm (qui est installé depuis presque un an sur mon ordinateur et jamais eu de souci jusqu'à maintenant) pourrait être la cause. Serait-ce la source du problème?
Je vous remercie d'avance pour votre aide en esperant que vous avez fait une bonne lecture!
