Part 1. What Is A Bad Pool Header?

A bad pool header indicates a problem with the computer’s memory allocation, but can also be caused a lot of factors including disk writes, RAM, device drivers, and some routers.

Pool refers to the memory pool in Windows which allocates memory. A header is the header annotation that determines how parts should use certain values and parameters. Thus, a bad pool header may happen when the memory pool header is corrupted due to some processes that may have affected the memory.

Usually, the most common scenarios would be:

• Faulty RAM
