Memory Management BSOD while surfing the internet - Win 7 64bit

The timings look fine, and it's normal for the clock frequencies to be detected as half the amount printed on the RAM stick.

I see. At least now I don't have to worry that there is anything wrong with my Ram sticks. It makes me wonder what it was really that caused the memory management BSOD.

The driver started writing into memory address spaces which wasn't allocated to it, and therefore corrupted the number of PTEs within the page table.

Looking back over the first dump file, we can see that the reference count for the number of used PTEs has dropped below zero:

Code:

0: kd> dt nt!_MMPFN fffffa80008fa0f0
   +0x000 u1               : <unnamed-tag>
   +0x008 u2               : <unnamed-tag>
   +0x010 PteAddress       : 0xfffff6fb`40000bc8 _MMPTE
   +0x010 VolatilePteAddress : 0xfffff6fb`40000bc8 Void
   +0x010 Lock             : 0n1073744840
   +0x010 PteLong          : 0xfffff6fb`40000bc8
   +0x018 u3               : <unnamed-tag>
   +0x01c UsedPageTableEntries : 0xffff <-- Parameter 3
   +0x01e VaType           : 0 ''
   +0x01f ViewCount        : 0 ''
   +0x020 OriginalPte      : _MMPTE
   +0x020 AweReferenceCount : 0n128
   +0x028 u4               : <unnamed-tag>

Code:

MEMORY_MANAGEMENT (1a)
    # Any other values for parameter 1 must be individually examined.
Arguments:
Arg1: 0000000000041790, A page table page has been corrupted. On a 64 bit OS, parameter 2
    contains the address of the PFN for the corrupted page table page.
    On a 32 bit OS, parameter 2 contains a pointer to the number of used
    PTEs, and parameter 3 contains the number of used PTEs.
Arg2: fffffa80008fa0f0
Arg3: 000000000000ffff
Arg4: 0000000000000000

Thanks for the patient explanation. I'm in a dilemma as to whether to uninstall the logitech driver since I don't have any alternative driver to fall back on. So far the PC doesn't give me any BSOD after that. Will Windows 7 provide a suitable driver for this if I were to uninstall the logitech driver?

I doubt it would, but you could try it and see if it auto-configures a generic Windows driver.

Straight after I uninstalled the Logitech webcam driver, Windows automatically installed drivers for it and the webcam is shown as 'USB composite device' under Devices and Printers.

That's good, does the webcam still work?

Sorry for the late reply. Seemed that the webcam is working fine.

That's great, have you had any other issues? Otherwise, you may mark this thread as solved :)

Hi, I'm back here again because I have just got a memory management BSOD after the first one seemed to be somehow solved (as such I am now marking it as unsolved). The culprit seems to be the same - ntoskrnl.exe. If there is a need for me to start a new thread, please let me know.
