Frequently Asked Questions

Is PFN_LIST_CORRUPT a memory-related error?
Yes — it specifically relates to corruption in how Windows tracks physical memory pages, which points strongly toward either a driver bug or genuinely faulty RAM as the underlying cause.
How reliable is Windows Memory Diagnostic at catching this?
It's a solid first check, though a more extended, dedicated memory-testing tool run overnight can sometimes catch intermittent faults the quicker built-in test misses.
