Ecran bleu depuis nouvelle config

Bonjour à tous,

J'espère etre dans la bonne section pour mon problème.

Depuis environ 15 jours maintenant j'ai changé mon pc. J'ai réinstallé mon Windows 7 mais j'ai remarqué que quelques fois mon pc ne s'éteignait pas complètement. Enfin le ventirad continue de trouner apres avoir eteint l'ordi et seul un appui long sur le bouton lui permet de s'éteindre totalement et de redémarrer.
En plus il me signale un soucis au redémarrage et me dirige vers le bios, mais aucun paramètre n'a changé.

Enfin hier j'(ai eu 2 écrans bleu. N'en connaissant pas la cause et n'ayant jamais eu à faire à ce genre de problème j'ai analyser avec Whocrashed. En voilà le rapport :

If no updates for these drivers are available, try searching with Google on the names of these drivers in combination the errors that have been reported for these drivers and include the brand and model name of your computer as well in the query. 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. 

Donc apparemment c'est un soucis de directX et Avast.

J'aurais voulu avoir votre avis. Merci à vous
