Salut, j'ai un problème avec mon ordinateur, il plante tout seul d'un seul coup, il me l'a fait là il y a environs 10 minutes.

Le truc bizarre, c'est que ce problème je l'avais eu même il y a de ça plusieurs mois, j'ai depuis changé de disque dur et le problème recommence... Là ça me l'a fait tout à l'heure mais il n'avait plus planté anormalement depuis environs 2 semaines et il recommence aujourd'hui...

J'ai regardé dans "Observateur d'événements" et il y a ce message d'erreur :

Et aussi ça :

Y'a aussi quelques autres erreurs...

Voici un rapport (copié/collé) du logiciel "WhoCrashed"

Si quelqu'un peut m'aider

Welcome to WhoCrashed (HOME EDITION) v 5.03
--------------------------------------------------------------------------------

This program checks for drivers which have been crashing your computer. If your computer has displayed a blue screen of death, suddenly rebooted or shut down then this program will help you find the root cause and possibly a solution.

Whenever a computer suddenly reboots without displaying any notice or blue screen of death, the first thing that is often thought about is a hardware failure. In reality, on Windows most crashes are caused by malfunctioning device drivers and kernel modules. In case of a kernel error, many computers do not show a blue screen unless they are configured for this. Instead these systems suddenly reboot without any notice.

This program will analyze your crash dumps with the single click of a button. It will tell you what drivers are likely to be responsible for crashing your computer. It will report a conclusion which offers suggestions on how to proceed in any situation while the analysis report will display internet links which will help you further troubleshoot any detected problems.
