PF_DETECTED_CORRUPTION

Page-file corruption detected for PF_DETECTED_CORRUPTION

PF_DETECTED_CORRUPTION is bug check code 0x00000191.

This bug check points at page-file or paging metadata corruption. It is distinct from ordinary low memory: the system detected inconsistent data in a paging path that is required for safe memory management.

How to read it in a dump

  • Check paging file configuration, disk errors, storage filters, and memory-management state.
  • Corruption can originate in storage, memory, or a driver writing to wrong memory.
  • A full or kernel dump is more useful than a minidump.

What to check

  • Run storage diagnostics and memory tests after preserving the dump.
  • Check disk, controller, and filter-driver event logs.
  • Inspect page-file location and recent changes to paging configuration.
