Crash dump

Hi,

I installed Windows 7 about 3-4 weeks ago and it's been crashing almost every day ever since. I analyzed memory dumps with WHOCRASHED and checked all symptoms through google and did everything that was suggested to other users with the same or similar symptoms, but nothing helped. I updated bios, changed to default settings, updated all drivers, checked memory with Windows Memory Diagnostic (it ran for over 24 hours), changed the power supply and even formatted the drive and installed a fresh copy of windows yesterday and still no change.

I'm guessing it has to be hardware (Motherboard, RAM (diagnostic test has passed ok?) or CPU). Everything except CPU is new, I got used CPU at very cool price, but now I'm thinking it might have been overclocked.

All minidumps are inside the attachment. I think that since nearly everthing has been tried, the short versions wouldn't help much so if anyone knows how to interpret those minidumps, please check them and let me know any possible suspicion.


Quick system specs:

Motherboard: Gigabyte G41M-ES2l (integrated VGA, LAN, SOUND)
CPU: Intel Core 2 Duo E6320
RAM: PatriotDDR2, 2GB PC2-6400 800MHZ
HDD: WD5000AACS (500 GB, 16 MB Cache, SATA)
DVD-RW: NEC, some old model
PSU: Lc Power 500 W
OS: Windows 7 Ultimate 6.1 (Build 7600) + all windows updates

Thanks

Here they are...


And here is the result of the system scan:

C:\Windows\system32>sfc /scannow

Beginning system scan. This process will take some time.

Beginning verification phase of system scan.
Verification 100% complete.

Windows Resource Protection did not find any integrity violations.

C:\Windows\system32>

I'll leave the memory test running over night and post the results tomorrow.

Thx

Typically caused by drivers passing bad memory descriptor lists (ie: calling
MmUnlockPages twice with the same list, etc).  If a kernel debugger is
available get the stack trace.

Here are the results of memory test (no errors found):

Also, just before the last crash, while browsing with firefox, I remember that "no network" icon appeared in the taskbar and firefox stopped responding. I don't exactly know on what basis does this icon appear, but the computer was certainly not unplugged from the LAN (Netgear switch) and when I checked later, modem/router had been online for several days with no disconnection from ISP.

I launched Driver Verifier today and got this bsod immediately after the reboot:
