How to Fix PFN LIST CORRUPT in Windows 10 (BSOD).
Windows 10 uses an index called the page frame number (PFN) database to distinguish between free and allocated portions of physical memory. It consists of several lists – “Active”, “Standby”, “Modified”, etc., which provide the operating system with the necessary information.
However, if the list in the PFN database is corrupted, you will most likely experience a complete system crash with its accompanying blue screen of death (BSOD) stop code PFN_LIST_CORRUPT.
Outdated or faulty device drivers and conflicting system settings are common causes of the PFN_LIST_CORRUPT BSOD. Seriously though, disk related errors and faulty RAM (random access memory) can also damage PFN lists.
If you continue to encounter the PFN_LIST_CORRUPT BSOD repeatedly, you can fix it by going your way through the list of solutions below.
Note. If BSOD PFN_LIST_CORRUPT prevents Windows 10 from booting, try booting the operating system in Safe Mode.
Update Device Drivers
The latest device drivers help fix most BSOD errors in Windows 10, so it’s best to install them on your computer first.
You can get new drivers for hardware components such as graphics card and motherboard by searching the websites of manufacturers – NVIDIA, AMD, Intel, Dell, HP, etc. Alternatively, you can use a driver update tool such as DriverPack, DriverUpdate or Driver Booster to speed up the process.
Microsoft also releases driver updates from hardware manufacturers through Windows Update. You can access them by going to Start> Settings> Update & Security> Windows Update> See All Additional Updates> Driver Updates.
Update Windows 10
In addition to the drivers, you should also update Windows 10. This should fix any known operating system issues related to PFN database corruption.
Open the Start menu and select Settings> General> Windows Update to find and apply the latest operating system updates.
Roll Back or Reinstall Drivers
If the PFN_LIST_CORRUPT BSOD problem started immediately after applying a specific driver update, you should rollback or reinstall it. You can use Nirsoft’s free BlueScreenView applet to analyze BSOD dump files and identify the problematic driver.
Roll back driver
Press Windows + X and select Device Manager to open Device Manager. Then find and right-click the driver you want to rollback and select Properties.
In the Properties dialog box that appears, go to the Driver tab and select Roll Back Driver. This should revert the driver to its previous version.

If you have a third-party antivirus program installed on your computer, check if disabling it helps. so if, uninstall it and go back to using Windows Security.
If you keep Windows 10 up to date and take precautions when surfing the Internet, Windows Security should provide adequate protection.

Fix Corrupt System Files and Drive Errors in Windows Recovery Environment
Let’s say the PFN_LIST_CORRUPT BSOD issue is severe enough that you can’t boot Windows 10 in Normal or Safe Mode. In this case, you can run the System File Checker and Check Disk utility by entering the Windows Recovery Environment (WinRE). In WinRE, select Command Prompt and run the following commands.
If necessary, use the DiskPart command-line utility to identify (and replace) the drive letters associated with the boot volume and Windows 10 partition.
Run the System File Checker
Copy and paste the following command into the command line console and press Enter:
sfc / scannow / offbootdir = C: / offwindir = D: Windows
Run Check Disk Utility
Run both commands one after the other to fix disk errors on both the boot volume and the Windows 10 partition.
Boot volume: chkdsk C: / r
Windows 10 partition: chkdsk D: / r
Check the RAM on Your PC
Defective RAM modules can also lead to the PFN_LIST_CORRUPT BSOD. Run the Windows Memory Diagnostic Tool to check for bad memory.
To do this, press Windows + R, type mdsched.exe and select “Open.” Then select Restart Now and check for problems.
When the tool finishes scanning your computer, press Windows + X and select Event Viewer.
In the Event Viewer window that appears, select Windows Logs> System in the left pane. Then choose Action> Find and search for Memory Diagnostics to open the Windows Memory Diagnostic Report.
If you see any errors, you need to replace your computer’s RAM.
Reset Windows 10
If none of the above fixes helped, you need to restore Windows 10 to factory settings. You can keep your data intact or completely reset your operating system.
To reset your operating system, go to Settings> Update & Security> Recovery> Get Started and follow any on-screen instructions.
Alternatively, you can reset Windows 10 through the Windows recovery environment. Once WinRE has loaded, select Troubleshoot> Reset this PC.
Reinstall Windows 10
If restarting your computer doesn’t work, try erasing your computer and reinstalling Windows 10 using a bootable installation USB drive.
Since reinstalling the operating system will permanently delete all data, be sure to back up your data beforehand.
