Frequently Asked Questions

Does BAD_POOL_HEADER indicate failing RAM?
It can, alongside driver issues — both memory problems and driver bugs can produce this specific pattern of pool corruption, which is why running Windows Memory Diagnostic alongside driver checks is worthwhile.
Is this stop code common?
It's less common than codes like IRQL_NOT_LESS_OR_EQUAL, but it follows similar general troubleshooting logic — drivers, memory, and system file integrity are the main areas to check.
