STOP 0x00000019
BAD_POOL_HEADER
The header that tracks a block of Windows' shared kernel memory was corrupted — a driver wrote past the end of its allocation, or RAM is faulty.
Likely causes, most common first
- A buggy driver overwriting pool memory
- Faulty RAM
- Security or VPN filter drivers
How to fix it
1. Update drivers and test RAM easy
- Update the driver named in the report (or your network/security drivers if none is named).
- Run Windows Memory Diagnostic.
- Uninstall recently added VPN/antivirus utilities temporarily.
