Windows 7: Multiple BSODs, no common activity

QPhysics · 26 Jan 2013

After months of perfectly stable operation, I've suddenly started getting lots of BSODs, six in one day! I haven't installed any new hardware or software; I've run tests on the RAM and hard drive and found no errors; sfc \scannnow says all the system files are fine.
WinDbg lists several different files as being the causes of the BSODs, and there's no common program or activity I'm running/doing that causes the crashes. This morning I turned the computer on to a BSOD.

Help me, SevenForums, you're my only hope.

Your actual problem is a very old nForce driver.

Code:

fffff880`033cadf0  fffff880`02f1dd90Unable to load image \SystemRoot\system32\DRIVERS\nvmf6264.sys, Win32 error 0n2

A search revealed that you are using nForce as the chipset driver, and that includes nvmf6264.sys as the network controller driver. You need to try to update nForce, as it contains not only the network controller, but also storage controller and a lot of other vital drivers.

Go to Drivers - Download NVIDIA Drivers, search for nForce, as per your motherboard's chipset specifications.

Also, Comodo firewall adding to it.

Code:

fffff880`033ca498  fffff880`0175e29bUnable to load image \SystemRoot\System32\DRIVERS\cmdguard.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for cmdguard.sys
*** ERROR: Module load completed but symbols could not be loaded for cmdguard.sys
 cmdguard+0xd29b

Better you uninstall Comodo, and use windows inbuilt firewall.

Let us know the results.

Two more BSODs after updating the nForce drivers. I was surprised that they were reported as being an issue because I just updated those a month or so ago.
The first BSOD happened when I shut down my music player (MusicBee) last night, so I checked my audio drivers but they all say they're up to date. The second was waiting for me when I turned on the computer, so I don't know what might have been going on in the background when it occurred.

Thanks

Both the crash dumps are apparently very silent.

Code:

BugCheck 3B, {c0000005, fffff96000153354, fffff8800874cfa0, 0}

Probably caused by : win32k.sys ( win32k!HmgSetLock+28 )

Probably caused by : cng.sys ( cng!GatherRandomKey+294 )

Followup: MachineOwner
---------

And both of them came with different bugcheck codes.

Though, a deeper search identifies nForce again as failing.

Code:

fffff880`033b63a0  fffff880`01035964*** WARNING: Unable to verify timestamp for nvstor64.sys
*** ERROR: Module load completed but symbols could not be loaded for nvstor64.sys
 nvstor64+0x15964

Though you have updated it.

Code:

In such a situation, it is better to enable Driver Verifier to monitor the drivers.
Driver Verifier - Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

Information

Why Driver Verifier:
It puts a stress on the drivers, ans so it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.

How Can we know that DV is enabled:
It will make the system bit of slow, laggy.

Warning

Before enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.

If there is no points, make a System Restore Point manually before enabling DV.

Tip

If you fail to get on the Desktop because of DV, Boot into Advanced Boot Options > Safe mode. Disable DV there. Now boot normally again, and try following the instruction of enabling DV again.
If you cannot boot in Safe mode too, do a System Restore to a point you made earlier.

Let us know the results, with the subsequent crash dumps, if any. Also Test your RAM modules for possible errors.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 passes, preferably overnight.

I've already run Memtest86+. I put in one stick at a time and ran it, then put all four in together and ran it. No errors.

I'll enable verifier and let you know when I have any results to share.

QPhysics · 29 Jan 2013

I think this is an official candidate for weirdest computer issue ever.
I ran verifier.exe for over 34 hours and, other than being a tiny bit laggy, there were no issues. No crashes, no freezes, no BSODs.
So I turned off verifier and rebooted...and before Windows got me fully logged in...BSOD!
Reboot...start the SF_Diagnostic_Tool to gather the information...and BSOD!

I've never heard of a system that was stable with verifier on and crashed twice in less than 20 minutes when it was shut off. Have you?

Anyway, diagnostic tool output attached...hopefully you'll spot something I missed, because I don't see a thing here that I would point to as the cause.
I was thinking about running verifier on the Microsoft drivers too...but that's just as likely to cause a completely unrelated crash as to actually pinpoint the driver that's actually bad, right?

The supplied data says that Comodo is still there, it is starting up with windows, and its safe delete filter causing problems on logon.

Anyway, you have 24 items stored in startup, and among them, Super Antispyware and PC Doctor is not needed in not only startup, but also for the system. Free up the startup.

Click on the Start button
Type “msconfig (without quotes), click the resulting link. It will open the System Configuration window.
Select the “Startup” tab.
Deselect all items other than the antivirus.
Apply > OK
Accept the restart.

Auslogics. Nice for XP. Harmful for windows 7.

Which antivirus do you use? I am failing to find any.

Comodo Internet Security has an antivirus, firewall, and program control all-in-one.

QPhysics · 29 Jan 2013

The only thing I can find is that when verifier.exe is running, FreshIO doesn't appear in the drivers list. Is it possible that freshIO is the problem (it does have a lot of hardware interaction) and verifier is keeping it from loading instead of crashing when it tries to load? That would be odd behavior for verifier (or maybe I just don't understand verifier as well as I thought I did), but if that fixes it, I'd be happy.

Arc · 29 Jan 2013

As I can say, comodo is the main issue here remaining. Uninstall it using Revo Uninstaller, advanced mode. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.

Download, install and update those, and then run full system scans with both of them, one by one.
