Windows 7: Frequent BSOD recently; not sure what caused it.

Frequent BSOD recently; not sure what caused it.

Sorry for the poor title, but I didn't get enough time to read the BSOD before it restarted the computer.

I have received BSOD 3 times in the past two days (all the same message but it disappears before I can read it). I have received maybe 2 or 3 others in the past couple months but it wasn't often.

Attached are the dumps created with the SF diagnostic tool. Only thing that I noticed that was out of the norm was that my fan seems to be running quite often compared to normal.

I would appreciate any advice as this is relatively a new laptop.

Recommended from a strict BSOD perspective, compatibility & stability compared to other antiviruses/internet security software. It is free and lightweight:-

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.

Please uninstall DAEMON Tools/Alcohol 120%. 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

Thank you for the detailed reply koolkat77. It is unfortunate that I must get rid of those two programs as I like them both very much. Do newer versions of the programs cause any issues?

As for anti-virus, you suggest I use both MSE and Malware bytes? Isn't it generally a bad idea to have two anti-virus?

I will print this out and remove them later today. (I'm off to work for now but I can hopefully get to fixing this up tonight!)

Security essentials is an antivirus, Malware bytes is an anti malware app.

You may try the newer version of bit defender but I would suggest you to use MSE for the time being and see if the BSOD-s reoccur.

  • Removed Alcohol 120% (BSOD on first attempt to uninstall - restarted in safe mode and uninstalled it)
  • Ran tool to disable driver
  • Removed BitDefender
  • Installed MSE
  • Ran MSE
  • Installed MalwareBytes AntiMalware
  • Ran MalwareBytes (found 2 BHO / browser hijacker and removed them: Trojan.Happili & Trojan.BHO) -- that explains why my browser was so slow and the cache was always 170mb+
  • Started SFC /scannow - BSOD again (was browsing on firefox when it happened)

It was doing well for a good amount of time before I got the BSOD again.

Restarting SFC /scannow

To Do:
  • SFC /scannow found no issues
  • Disk Check
  • Reduce Start-up Programs
  • Troubleshoot App Conflicts by Performing a Clean Startup


Will keep updating post as I complete each new task.

Another update, SFC scan completed without issues.

I accidentally opened FireFox again (default browser) and surprise, BSOD (same one stop at 0x0000051). Do you think the two BHOs have something to do with this? Perhaps attached to my default browser and caused an issue? I'm using chrome at the moment as a backup.

If FireFox could be the issue, I should be able to keep my bookmarks without issue, correct?

Lastly, I recall why I switched from MalwareBytes to BitDefender...MalwareBytes blocks many sites that I like to use. I never took the time to fix the firewall settings since I didn't want to do it for 2 dozen websites.

I'm also about to start my Disk Check (it will require me to reboot - about to do so)

Could be as the usual causes for that bug check have "security issues" listed.

Code:
STOP 0x00000051: REGISTRY_ERROR  

Usual causes:  Hardware failure, File system corruption, Security issues
Maybe you should uninstall and reinstall the browser.

Disk check went fine.
Removed a few start up apps.
Will look into setting up a clean start up tomorrow.
Going to export bookmarks in firefox, uninstall it, then reinstall it (then head to bed).

Is there any type of log you'll need when I come back tomorrow? (aside from wanting to hear if I'm still getting BSOD when Firefox is reinstalled)


Edit

Uninstalled firefox
Reinstalled firefox and set it to default browser
Got BSOD again. Rebooted computer and chrome won't even start up now. (stuck using IE until further notice)

Will check in tomorrow when I wake up. I'm thinking I should start booting up in safe mode with networking.
