Crash Windows récurent - blue screen

Bonjour,

mon PC crash depuis que l'ai acheté: blue screen. J'ai tout changé ou presque (alimentation, OS, DD, mémoire...)

Après analyse par le logiciel WhoCrashed, voici le rapport:

On Tue 25/01/2011 17:47:46 GMT your computer crashed
crash dump file: C:\Windows\Minidump\012511-12870-01.dmp
This was probably caused by the following module: ntoskrnl.exe (nt+0x70740)
Bugcheck code: 0x1A (0x41790, 0xFFFFFA80007EE460, 0xFFFF, 0x0)
Error: MEMORY_MANAGEMENT
file path: C:\Windows\system32\ntoskrnl.exe
product: Microsoft® Windows® Operating System
company: Microsoft Corporation
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.

Quelqu'un peut-il m'éclairer?

Merci par avance
