PFN_LIST_CORRUPT

What it means

Windows' list of physical memory pages got corrupted, usually by a driver or bad RAM.

Common causes

• Faulty RAM
• A buggy driver

How to fix it

1. Test the RAM: run Windows Memory Diagnostic (search mdsched) or MemTest86 from a USB stick. Any error means a stick or its speed setting is the problem.
2. Undo any overclock or undervolt, including XMP/EXPO memory profiles, and test at stock settings for a day.
3. Open the crash dump in WhoCrashed or BlueScreenView: it usually names the driver file that caused it (for example nvlddmkm.sys is the NVIDIA driver).
4. Update the graphics, chipset and network drivers from the maker's site (NVIDIA, AMD, Intel or your board vendor), not from a driver-updater tool.
