J'ai remplacé ma 8800GTS par un 6870. Parfaitement fluide dans crysis2 à 70 imps en moyenne (1920*1200)mais au bout de 10 minutes de jeux le PC fait un bluescreen. J'ai monitoré les températures et tout est plus que correct le gpu ne dépasse pas les 70°C le cpu idem. j'entend un peu l'alim mais il est largement en dessous de ses 500W (enermax) De temps en temps le pc même laissé en idle fait un bluescreen sachant qu'avant de changer la cg je pouvais passer des semaines allumé 24/7 sans faire de reboots.    
J'espère que c'est un problème logicielle: Mon Windows n'est pas a jour (je ne veux pas vraiment le mettre à jour...) pour l'installation j'ai désinstallé tout les drivers nvidea avant de mettre la radeon, puis j'ai mis les derniers drivers ati.
Peut être la Vram qui n'est pas au contact de dissipateur peut poser problème...

Bonjour,
télécharger 'who crashed", installez-le, lancez-le, faites "Analyse" bouton en haut à gauche.
Vous aurez les résultats sur la page courantes en déroulant vers le bas.
S'il vous dit qu'il n'y a pas de fichiers à analyser, attendez le prochain bsod et refaites l’analyse.
 
Who crashed analyse les fichiers DUMP créés par windows après un BSOD. Vous saurez quels sont les fichiers responsables.

pleure pas si tu prend le temps de lire le forum , rien que dans la 1 ere page tu a 7 personne avec ton problème.
 
mais pour vérifier c'est quoi ta config complete ?

ma config:
boitier p180
gigabyte sli ds4
QX6800 @2,93Ghz stable à 3,8 mais pas OC en ce moment à cause des crash
noctua NH-U12F
8 Go Kingston hyperX 6400 cl4
Samsung 500Go sata, Western digital 500 Go(memup en interne sur IDE)
enermax liberty 500w
Dell 24 WFP
SAPHIRE HD 6870 1go
 
J'ai passé mon anti-vir commodo sur paranoia et ça fait 12 heures que je n'ai plus de crash. ce mode bloque les applications en arrière plan de W7 qui pourrai bugger ainsi que d'éventuelles malwares. à voire si ça règle définitivement le problème.  
J'avais essayé de lire le fichier dump directement et j'avais abandonné cette idée. Merci pour le "who crashed" qui devrai me le décripter

On Sat 23/04/2011 18:27:31 GMT your computer crashed
crash dump file: C:\Windows\Minidump\042311-16442-01.dmp
This was probably caused by the following module: ntoskrnl.exe (nt+0x71F00)  
Bugcheck code: 0x1A (0x5003, 0xFFFFF70001080000, 0xA2C3, 0xA2C5000145A6)

description: NT Kernel & System
Bug check description: This indicates that a severe memory management error occurred.
This might be a case of memory corruption. More often memory corruption happens because of software errors in buggy drivers, not because of faulty RAM modules.  
The crash took place in the Windows kernel. Possibly this problem is caused by another driver which cannot be identified at this time.

nvlddmkm.sys  

peut etre un conflit avec le driver Nvidia qui n'est apparemment pas complètement désinstallé. Mais je ne trouve rien en cherchant dans le disque dur.
 
ntoskrnl.exe plante=> un processus critique dans le cycle de botte-vers le haut de votre ordinateur (?)  
nvlddmkm.sys plante => driver nvidea video
hal.dll => sert dans le boot?

Faut absolument que tu désinstalles le reste des drivers nvidia avec ceci:
http://downloads.guru3d.com/Guru3D [...] d1655.html
Procédure:
- Désinstalle les drivers nVidia (NVIDIA driver + NVIDIA PhysX + NVIDIA Stereoscopic 3D driver).
- télécharge Driver Sweeper
- redémarre windows en mode sans échec
- installe Driver Sweeper
- Lance Driver Sweeper
- sélectione les applications à nettoyer (nVidia display + nVidia Physx) clique sur "Analyse" puis "clean"
- A l'invitation, redémarre Windows
- Par la suite la console s'ouvre au redémarrage et propose d'effacer les fichier qui se trouve sur C:
- Elimine le reste des composants sur C:\NVIDIA
