Bonjour , alors voila je crée un sujet car depuis quelque temps le pc de mon frère ne fait que bluescreen sur bluescreen , tout d'abord sa config :
CM : gigabyte p55 ud3l
CPU : i5 760 non oc
CG : hd 7950
alim : corsair vs 550
ram : PC G.SKILL VALUE DDR3 2 X 4 GO 1333 MHZ NS
Windows 8.1
Donc deja voila , a savoir que tous les pilotes sont a jour , les températures sont plus que correct , par exemple le proc est a 35-38 degrés sur le bureau et en jeux max 65 degrés . La carte graphique , proc et ram sont fonctionnelles , tester sur un autre pc. je vous laisse aussi le rapport de who crashed :
