BSODs - all contain ntoskrnl.exe

[ashotinthedark]

I've had my lenovo T420 laptop since August of 2011, and I believe I had one or two blue screens sometime in 2011 or early 2012 (but it doesn't appear on my dump files, so maybe I'm wrong?). But my major blue screen problems started just a month ago.

The History: I had an issue with Mcafee Antivirus where it locked down my internet for a few days (as I later discovered). At the time, all I knew was that internet wouldn't work on my computer. I took my computer to an IT guy and we messed around with network settings (including turning off ivp6) but couldn't seem to get the internet back on track. He concluded that it was a virus.

I ran Super-Anti-Spyware, Combofix, and malwarebytes, but could not find anything serious. Eventually a family member told me that he had uninstalled and reinstalled Mcafee Antivirus and that had fixed the issue. But I was fed up, so i uninstalled my Mcafee and installed free versions of Avast Antivirus and ZoneAlarm. This whole fiasco happened during the week of August 19-25.

As the minidumps show, my blue screen problems began on August 30 and have been occurring with increasing frequency ever since, with about 5 blue screens in the past 2 weeks. The most recent blue screen happened today just as I was uninstalling ZoneAlarm. Tonight, I uninstalled ZoneAlarm (it uninstalled successfully on the second try) and Hamichi, a VPN software.

Other programs: Not sure if my zip file shows it, but other recently installed prorgams include F.lux, intelWireless wifi update, google talk plugin, windows driver kit, bluescreen, microsoft document explorer 2008, update for Evernote, power manager for lenovo, launchy 2.5, intel HD graphics driver on 10/9/2012...etc.

Hardware: In terms of hardware changes, I installed a new stick of RAM this past June. As soon as I get the time, I'm gonna run memtest86+ and post the results here.

Setting: In terms of activities, I'm not sure I'm consistently doing anything when the blue screens occur. They seem to happen randomly.

Summary: I hope this information helped! I'm pretty clueless as to what's going on, but I saw that this was a vibrant community that had helped lots of people and decided to post. If I need to provide additional information, please let me know. I really need to get this laptop back on track.

Thanks for the help, I appreciate it!

Welcome to SevenForums

I'm going through your .dmp files, will report anything I find. Can you tell me if McAfee is currently installed on your laptop?

Fill in your system specs as well:

McAfee is currently not installed on my laptop.

 

[koolkat77]

Good to know that. McAfee is quite problematic and is alone a cause of Blue screens.

Daemon Tools
Please uninstall DAEMON Tools. It uses a driver called sptd.sys which is known to cause BSODs in Windows 7. Uninstall the software using Add/Remove Programs. Reboot the system. Once the program is uninstalled, run sptd.sys uninstaller to remove the driver from your system.

As an alternative, many people recommend the use of Total Mounter or Magic ISO

OR, Prefer 7zip out of all:
Download and install 7-Zip, it is free +it can extract any iso file. So you can use it the way you want to. At a max you'll miss some chapter chooser screen of a DVD title.

Avast! antivirus contributes in BSOD-s. Please uninstall it and replace with MSE, at least to test.

Recommended antivirus program for Windows 7 based on stability compared to others:-

• Microsoft Security Essentials - Free Antivirus for Windows
• Malwarebytes - The Free version
• http://www.sevenforums.com/system-security/206705-good-free-system-security-combination.html

:warn: Do not start the free trial of Malware Bytes; remember to deselect that option when prompted.

Run a full scan with both (separately) once downloaded, installed and updated.

Check for onboard vga drivers/chipset/motherboard drivers from Intel Download Center

Run the System File Checker that scans the of all protected Windows 7 system files and replaces incorrect corrupted, changed/modified, or damaged versions with the correct versions if possible:

• http://www.sevenforums.com/tutorials/1538-sfc-scannow-command-system-file-checker.html

Free up the start-up, nothing except the antivirus is needed there:

Uninstall the Intel Rapid Storage stuff from your computer for the time being. You may get the latest drivers/version from here later if necessary.

VirtualBox network drivers are also causing a problem, check for later/newer drivers if possible. Get them from here

And sorry to say..but Zone Alarm is also contributing in these crashes.

Look for appropriate removal tool by searching in Google, or uninstall using Revo Uninstaller - Free [ Advanced Mode ]

Post updated.

Blue screens had been quiet until yesterday night.

I've posted updated dump files in this message.

I've been really busy but I've followed almost all of the recommendations except for uninstalling intel rapid storage (will get around to that as soon as I can!)

here's my file :

Running system file checker yielded 0 errors. I uninstalled daemon, but after the computer rebooted, I tried the sptd.sys uninstaller and it said sptd.sys was not installed. Maybe daemon uninstaller took care of it?

I'm hoping this isn't a hardware problem. I ran memtest86+ the other day and it didn't turn up any errors after 8 passes.

Hopefully this is still something that can be fixed by uninstalling/reinstalling stuff....

 

[koolkat77]

Hmm. Looks like a network related crash. Did you remove Zone Alarm?

I removed zonealarm about a week ago, but I did it through the windows control panel. It gave me a blue screen while I was uninstalling it. After the computer rebooted it, I tried uninstalling zonealarm again and it seemed to work that time.

I'm not sure how to use driver fusion/sweeper. How do I know which driver on its list applies to zonealarm's drivers? I don't see anything on the driver inspection list that says "zonealarm." There is one entry called realtek that is described as network.

Thanks!

 

[koolkat77]

Sorry that was meant for the e1c62x64.sys drivers.. The link on my post #7 is for e1c62x64.sys not for zone alarm

 

[ashotinthedark]

Using RevoUninstaller, I found a stray fragment of the ZoneAlarm files that had not yet been deleted. I then used RevoUninstaller to delete that stray ZoneAlarm fragment.

It has been about three weeks since my last bluescreen.

As a last question, I've done nearly everything recommended except uninstall the intel rapidstorage thing. I'm not sure how to do that, and I don't see it in my program/files menu. Is there any other way to find it and uninstall it?

Anyways, my main point is that so far, things are going swell. I will post any updates if new blue screens develop. In the meantime, I'd like to thank Koolkat77 and sevenforums for helping me with my blue screen problems. I would not be in such a nice place with this computer without you guys.

Happy Holidays!
