[b]STOP: 0x0000000A
IRQL_NOT_LESS_OR_EQUAL
This Stop error, which can be caused by either software or hardware, indicates that a kernel-mode process or driver attempted to access a memory location it did not have permission to access or a memory location that exists at a kernel interrupt request level (IRQL) that was too high. A kernel-mode process can access other only processes that have an IRQL that's equal to or lower than its own.
