0x0000004AIRQL_GT_ZERO_AT_SYSTEM_SERVICE — a thread returned to user mode from a system call while its IRQL was still above PASSIVE_LEVEL.
0x00000050PAGE_FAULT_IN_NONPAGED_AREA — invalid system memory was referenced (a wrong or freed memory address).
0x0000005CHAL_INITIALIZATION_FAILED — the Hardware Abstraction Layer failed to initialize during startup.
0x0000007BINACCESSIBLE_BOOT_DEVICE — Windows lost access to the system partition during startup.
0x0000007ESYSTEM_THREAD_EXCEPTION_NOT_HANDLED — a system thread generated an exception the error handler did not catch.
0x0000009FDRIVER_POWER_STATE_FAILURE — a driver is in an inconsistent or invalid power state during a power transition.
0x000000A0INTERNAL_POWER_ERROR — the power policy manager experienced a fatal error.
0x000000BEATTEMPTED_WRITE_TO_READONLY_MEMORY — a driver tried to write to a read-only memory segment.
0x000000C2BAD_POOL_CALLER — the current thread made a bad kernel memory pool request.
0x000000C4DRIVER_VERIFIER_DETECTED_VIOLATION — the general bug check Driver Verifier raises when it detects a fatal driver error.
0x000000C5DRIVER_CORRUPTED_EXPOOL — the system tried to access invalid memory at an IRQL that was too high while the pool was corrupted.
0x000000D0DRIVER_CORRUPTED_MMPOOL — the system tried to access invalid memory at an IRQL that was too high.
0x000000D1DRIVER_IRQL_NOT_LESS_OR_EQUAL — a kernel-mode driver accessed pageable memory while the IRQL was too high.
0x000000E2MANUALLY_INITIATED_CRASH — the user deliberately triggered a crash dump from the kernel debugger or keyboard.
0x000000EFCRITICAL_PROCESS_DIED — a process critical to system operation terminated.
0x000000F4CRITICAL_OBJECT_TERMINATION — a process or thread crucial to system operation unexpectedly exited or was terminated.
0x00000101CLOCK_WATCHDOG_TIMEOUT — an expected clock interrupt on a secondary processor was not received within the allotted interval.
0x00000109CRITICAL_STRUCTURE_CORRUPTION — the kernel detected corruption of critical kernel code or data.
0x00000124WHEA_UNCORRECTABLE_ERROR — a fatal hardware error reported through the Windows Hardware Error Architecture (WHEA).
0x00000133DPC_WATCHDOG_VIOLATION — the DPC watchdog fired due to a long-running DPC or prolonged time at DISPATCH_LEVEL or above.
0x00000139KERNEL_SECURITY_CHECK_FAILURE — the kernel detected the corruption of a critical data structure.
