Solved Random BSOD PFN_List_Corrupt

[gunner6486]

Lately I have been finding the computer on bsod occasionally. It has PFN_List_Corrupt at the top and I read a post to run verifier. when I restarted computer it kept going to bsod before it could even load up windows completely and said a driver was causing the problem. But I don't know which one. I turned verifier off in safe mode and tried to read .dmp file but was denied access. I have all files generated by sf diagnostics and I will upload them here. Any help would be appreciated

Welcome to Seven Forums.

MSINFO32:
Please go to Start and type in "msinfo32.exe" (without the quotes) and press Enter (you can also press Win and R at the same time to open the Run dialog - then type in msinfo32.exe and press Enter)
Save the report as an .nfo file, then zip up the .nfo file and upload/attach the .zip file with your next post.
Also, save a copy as a .txt file and include it also (it's much more difficult to read, but we have greater success in getting the info from it).

If you're having difficulties with the format, please open an elevated (Run as administrator) Command Prompt and type "msinfo32 /nfo C:\Users\Public\Desktop\TEST.NFO" (without the quotes) and press Enter. Then navigate to the C:\Users\Public\Desktop directory to retrieve the TEST.NFO file. If you have difficulties with making this work, please post back.

Avast! antivirus is often a cause of BSOD's on some systems. Please remove it using its removal tool from here:

• Uninstallers (removal tools) for common antivirus software - ESET Knowledgebase

Microsoft Security Essentials is recommended from a strict BSOD perspective.

• Microsoft Security Essentials, Free antivirus for windows
• Malwarebytes Anti-Malware Free
• Good and Free system security combination

   Warning

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.

Use the System File Checker tool (SFC.exe) to determine which file is causing the issue, and then replace the file.

To do this, follow these steps:

• Open an elevated command prompt. To do this, click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator. If you are prompted for an administrator password or for a confirmation, type the password, or click Allow. Use the System File Checker tool to troubleshoot missing or corrupted system files on Windows Vista or on Windows 7
  
• At the command prompt, type the following command, and then press ENTER: sfc /scannow
• The sfc /scannow command scans all protected system files and replaces incorrect versions with correct Microsoft versions. http://www.sevenforums.com/tutorials/1538-sfc-scannow-command-system-file-checker.html

Take memtest. Run for 8 passes and test each stick in a know good slot for an additional 6 passes.

   Note

Pay close attention to part 3 of the tutorial in order to rule out the faulty stick.

   Information

Errors are sometimes found after 8 passes.

   Tip

Do this test overnight, before going to bed.

Let us know the results.

Haven't had an instance since last post. Avast has always worked well for me on the last 3 or 4 computers. I have malwarebytes already and run regularly. Nothing dangerous found. I will attach msinfo file. I was just trying to find out what dmp file said was causing the problem.

• Please uninstall DAEMON Tools and any Alcohol % software. 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​

• Keep less stuff at the start-up. Only anti-virus, this helps avoid driver conflicts and improves time to log in to windows.
