The 0x0000001B or PFN_SHARE_COUNT error is related to the Page Frame Number (PFN) list, which is used by your system’s memory manager. The PFN list is a system data structure that OS uses to determine the current status of a page of physical memory.

This error may occur due to issues with your system memory, hardware problems, outdated or corrupted device drivers, system file corruption, or even due to software incompatibility.

How to fix:

  1. Update System and Drivers: Ensure your system and device drivers are updated to the latest version. Outdated drivers can lead to incompatibility and instability.
  2. Check Your Hardware: The issue might be a result of a hardware problem, so it’s a good idea to check your hardware components. If your computer has multiple RAM sticks, try removing and then reseating them, or try running the computer with one RAM stick at a time to identify if a specific stick is faulty.
  3. Run Memory Diagnostics: Use Windows Memory Diagnostic or a third-party tool to check your system for memory errors.
  4. Check for Disk Errors: Use the built-in Windows Check Disk utility to scan your system for hard drive errors. You can do this by opening Command Prompt as an administrator and typing “chkdsk /f”.
  5. System File Checker (SFC): Use the System File Checker tool to find and fix potential issues with your system files. You can do this by opening Command Prompt as an administrator and typing “sfc /scannow”.
  6. Perform a Clean Boot: Sometimes, third-party software can cause conflicts leading to a BSOD. Performing a clean boot can help isolate the software causing the problem.

Remember to back up your data before making significant changes to your system. If the problem persists, consider seeking help from a professional or Microsoft Support.
