Random BSOD's, tried most things

I installed a fresh copy of Windows 7 Ultimate x64 a few months ago due to BSOD and update issues with a previous install. I'm not sure if I'm having a continuation of the same problems or not. I thought it was most likely related to my OCZ Gold 2GB x 6 ram, which 3 sticks were 1600 and 3 sticks were 2000. I replaced them with G.SKILL Ripjaws 4GB x 3 and did the fresh install of Windows 7 around the same time. I did have a bad stick of G.SKILL and had it replaced and did another Memtest86+ pass to confirm it was fine this time.

Most of the BSOD dump files blame random things like ieexplorer and firefox I believe. I tried the simplest solution of uninstalling and re-installing the nvidia drivers. I still got more BSOD's. Next time I uninstalled the nvidia drivers and then ran DDU to make sure everything was removed. Then later I started with driver verifier. At first it blamed an nvidia driver so I uninstalled the nvidia drivers again, ran DDU in safemode this time, then installed only the graphics driver, physx driver, and hd audio driver.

Next driver verifier blamed my ESET smart security. I uninstalled and reinstalled that. Next it blamed my acronis true image. I uninstalled and reinstalled that. After that driver verifier would BSOD before windows login screen, an issue I had on my last windows 7 install. It would only flash the BSOD and not leave a dump file.

I ran Memtest86+ for 8 hours which only completed 3 passes, no errors. I'm not sure if I should check each individual stick in each slot, I thought I'd wait to see what direction others thought I should go first. I also ran checkdisk which said there were no bad sectors. Though I didn't think there would be since I use HD Tune to check my hard drives after a seagate 1.5TB started failing.

At this point I'm not sure if I need to do more ram tests, stress the graphics card, or try replacing ESET Smart Security with MSE. Though I've been using ESET Smart Security for years and would hate to have to replace it. I have family members that use it and have almost the same setup and have no issues.

I've also done sfc /scannow quite a few times and also a repair windows 7 install trying to fix a possibly unrelated svchost.exe memory leak problem related to network store interface service and internet explorer (nsi memory leaks fixed yet? - Microsoft Community). Which I've uninstalled and reinstalled the latest realtek network driver quite a few times for that. Still no fix for that besides another fresh install of Windows 7 apparently.

So I'm hoping someone more of an expert than I can help me figure this out. I usually use BlueScreenView and then WinDbg to look at the BSOD dump files. My last 2 BSOD's were for NETIO.SYS and fitmgr.sys. Which sounded like it could point more towards ESET this time.

Hi Yajiro.

You debugged the issue in almost the correct way. But the argument you stand for not uninstalling ESET is not very valid. Every computer is different. And ESET, though not very frequently, but contributes in BSODs that we have experienced many a times.

ESET is causing BSODs here.

Code:

BugCheck A, {0, 2, 1, fffff800030efbe6}

*** WARNING: Unable to verify timestamp for epfw.sys
*** ERROR: Module load completed but symbols could not be loaded for epfw.sys
Probably caused by : epfw.sys ( epfw+2069d )

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

So, why dont you uninstall it, at least as a test? In the mean time, use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.


Acronis is causing BSODs, too.

Code:

BugCheck CC, {fffff980129f8fe0, 0, fffff800035772aa, 0}

*** WARNING: Unable to verify timestamp for snapman.sys
*** ERROR: Module load completed but symbols could not be loaded for snapman.sys

Could not read faulting driver name
Probably caused by : snapman.sys ( snapman+26235 )

Uninstall it, too.

There may be some other things. Specially memory. 3 passes are not enough. To make it sure that the RAM is not failing, run memtest86+ for at least 8 passes.

Let us know the results.

About Acronis, updating is a worthy try.

About memtest86+, there is a specific methodology to obtain at the decision; and that needs to run the test with all the installed RAM on as the beginning.

The rest is obviously on you. You may not follow the standard ways. But that will complicate the troubleshooting procedure only.
