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

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

Encountered memory management BSOD while surfing the internet yesterday.

According to the mini-dump file, the BSOD is caused by ntoskrnl.exe. All important Windows 7 updates have been installed (SP1 and all post-SP1 updates). My present HDD is a new one bought about 2 days ago, so this is my first BSOD for this HDD. A chkdsk repair was done today, but there seemed to be no reported errors.

Welcome to the forums stg07,

Code:
BugCheck 1A, {41790, fffffa80008fa0f0, ffff, 0}

Probably caused by : ntkrnlmp.exe ( nt! ?? ::FNODOBFM::`string'+35084 )
Code:
Usual causes:  Device driver, memory, kernel
This bugcheck indicates that a serve memory management error has occurred, by looking at the first parameter, we can see that a page table page has become corrupt. The page table is used to store mappings between virtual and physical memory addresses.

Run Driver Verifier to scan for any corrupted drivers which may be causing problems, this program works by running various stress tests on drivers, in order to produce a BSOD which will locate the driver; run for least 24 hours:
information   Information
Run Memtest86+ for least 9-10 passes, and preferably overnight as it can take a while to fully complete.

Test each RAM stick individually, if an error is found then move the same RAM stick into the next DIMM slot and test again, if errors are found for the same RAM stick in every available slot then you have a faulty RAM module. On the other hand, if no errors are found in the next slot or the other slots for the same RAM module, then you have a faulty DIMM slot.

Test each RAM stick and every motherboard DIMM slot available.

It is a RAM, a bad RAM.

But if you have got a result like that:
testSlot1Slot2
RAM1ErrorGood
RAM2ErrorGood
It is a motherboard issue. The particular slot is bad.

Hi, I got this BSOD right after enabling the driver verifier and rebooting the system.

"A driver has over-run a stack-based buffer. This over-run could potentially allow a malicious user to gain control of this machine"

After rebooting into Windows, I disabled driver verifier and zipped up the memory dump file. I will now go on to test the Ram sticks.

That's great, thanks for uploading the dump file, and here's the analysis:

Code:
BugCheck F7, {158, f880023318d8, ffff077ffdcce727, 0}

Probably caused by : lvrs64.sys ( lvrs64+1972e )
Code:
Usual causes:  Device driver, Malware
The driver has written beyond the allocation for the stack buffer, and started to overwrite other memory addresses.

Code:
3: kd> lmvm lvrs64
start             end                 module name
fffff880`022eb000 fffff880`0233f000   lvrs64   T (no symbols)           
    Loaded symbol image file: lvrs64.sys
    Image path: \SystemRoot\system32\DRIVERS\lvrs64.sys

According to the support website (and its OS auto-detection function), the latest driver available for Windows 7 is version 2.51 and that is what I've installed. Does this mean I need to uninstall?

By the way, there are no errors detected for all available ram sticks and memory slots after running Memtest+ for at least 10 passes.

There is one strange thing that I've noticed. For Slot 2, the ram setting for both ram sticks is detected as 200MHZ, DDR 400 whereas in Slot 1, the ram setting for both ram sticks is detected as 666MHZ, DDR 1333. Is this normal?

Are both RAM sticks the exact same?

Unfortunately, you will need to remove the driver for the device, unless there is a available driver to roll back to?

Sorry for the newbie question, by 'exact same', you are referring to? All I know is that each ram stick is 2gb in memory capacity.

Doesn't seem to have any available driver to roll back to according to Device Manager.

Check the Logitech website for any older drivers for the camera, if no other drivers are available, then you will need to remove the driver completely.

Are the clock frequencies and timings on the RAM the exact same? They should be written on the RAM sticks.

Download CPU-z and then post the two screenshots for your system, for the SPD tab, post both DIMM slots. Here's how to upload the screenshots - Screenshots and Files - Upload and Post in Seven Forums

Here's my system as an example -
