Page Frame Number (PFN) list is a database that tracks the allocation of memory used by processes. This way, your system can check for available memory locations to allocate new processes.
Corruption of this list disables your PC from properly running system processes, thereby causing a Blue Screen of Death (BSOD) error.
In this article, we explain the reasons for the PFN_LIST_CORRUPT BSOD error and possible solutions.
There are a few reasons possible for the PFN list to get corrupted. Some of them are as follows:
Damage to RAM
Defective or outdated drivers
System file corruption
Overclocked memory
The most common causes for PFN list corruption include drivers and physical memory errors. So troubleshooting for such is certain to fix this issue.
Please find the methods to fix corruption in the Page Frame Number List below. We recommend following these methods in the mentioned order.
Deployment Image Servicing and Management and System File Checker scan and fix system file errors. They might fix this error if corrupt system files are the underlying reasons. Follow these directions to run these tools:
Type cmd on the Run tool (Windows + R). Then press Ctrl + Shift + Enter to launch the Elevated Command Prompt.
This error can also occur due to bad sectors or logical file errors in the system drive. Running the CHKDSK tool will likely fix this issue. Please follow the steps below:
Open the Elevated Command Prompt.
Operating System Updates include fixes for many preexisting bugs. It is best to keep your system fully updated to avoid system problems. You may be able to fix the PFN_LIST_CORRUPT error after updating Windows. Here’s how you can do so:
Press Windows + I to open Settings and go to Update & Security.
Overclocking your CPU can cause many memory issues. It might be one of the reasons for the PFN_LIST_CORRUPT error.
Note: Disabling overclocking is necessary before trying out many of the fixes below.
The standard method to disable overclocking is to restore BIOS to the default settings. Here are the steps to do so:
Restore your UEFI settings to default.
You’ll most likely find shortcuts or buttons for restoring to default on the UEFI settings screen. If not, don’t hesitate to get in touch with the manufacturer.
A faulty RAM is one of the most common reasons for this error. PFN list contains information about virtual and physical memory allocation states. So, a defective physical memory device, i.e., RAM, can cause this list to become corrupt.
Follow the instructions below to check for RAM defects:
Open the run tool and enter mdsched to run Windows Memory Diagnostic.
Wait for the result message after the reboot. It may take a lot of time.
The error message may be due to RAM or the motherboard slot. Test by using separate RAM sticks on different slots, and run this program to check for faulty hardware. Then replace the defective device to fix the issue.
You can also download and use other memory testing software if the Memory Diagnostics detects the error but fails to narrow down the cause.
A system crash creates a minidump file in the C:WindowsMinidump directory. You can use a debugger to open and analyze the minidump file to find out the cause for the crash.
Follow the instructions below to use the minidump file to determine the cause for the error:
Mount the ISO file on your PC and launch WinSDKSetup.
Follow the on-screen instructions while keeping the steps below on your mind.
Choose to install the software development kit on your computer.
Only check the Debugging Tools for Windows for features you want to install.
After installing the debugger, open the Elevated Command Prompt.
Now, search for and run WinDbg as administrator.
Press Ctrl + S on the WinDbg program.
Then, go to C:WindowsMinidump and open the minidump file created due to the system crash. Please be patient while WinDbg is loading the kernel symbols.
After the analysis, search for MODULE_NAME and probably caused by to determine the cause.
Search the internet for more information on the file responsible for the error. Then, remove, uninstall or reinstall the related programs.
Software error in faulty drivers is also a major reason for memory corruption. You can update all your available drivers or select problematic ones by analyzing the minidump file to resolve this issue. Follow the steps below to update your drivers:
Open the run tool and enter chúng tôi to launch the Device Manager.
Expand the device category.
Pick Search automatically for drivers
If your drivers are fully updated, you can try reinstalling them to solve errors in the driver software. Follow these instructions to do so:
Open the Device Manager and expand the device category.
Restart your PC. Your system automatically detects and installs any missing drivers.
If reinstalling proves useless, try rolling back to the last version. Also, make sure to use this method if you start encountering the PFN error after driver updates. Here’s how to rollback the drivers:
Launch the Device Manager and expand the device category.
Select Rollback Driver.
Driver Verifier performs various tests on your drivers to detect bugs and failures. You can carry out this test on multiple drivers at once. But it is recommended to only test the non-Microsoft drivers.
Note: This method puts heavy stress on your system. It may also cause further system problems. So, make sure to create a restore point before running Driver Verifier.
Enter verifier on run command to open the Driver Verifier Manager.
Here, select Create custom settings (for code developers) and hit Next.
Here, select all drivers except those provided by Microsoft.
Restart your PC and use your system normally.
Wait for your PC to crash. It will crash after about 24-72 hrs.
After rebooting, check the minidump file created due to the system crash using.
There may be unresolved bugs in a new system update. If you encountered this error after a system update, please uninstall it. Then, check if the issue resolves. If it doesn’t, you can install the update again anyway.

Malware programs are responsible for numerous system problems. It is always recommended to keep your system protected from any external threats. Please make sure to enable real-time protection and even cloud-based protection on a reliable antivirus.
Perform a full system scan or even a boot-time scan with your antivirus program whenever you encounter a BSOD error. Errors due to malware will likely get fixed after removing them.
Older versions of Windows (before Windows 10 version 1809) also have a Blue Screen Troubleshooter. Follow these steps to run this tool:
Open file explorer and paste Control PanelAll Control Panel ItemsTroubleshooting on the address bar.
Follow the on-screen instructions.
System Restore is a tool to revert the system to a restore point. This way, you can remove all system errors if you have an appropriate restore point. Follow these directions to perform a system restore:
Enter rstrui on the Run command (Windows + R). It will launch the System Restore tool.
