18 Fatal Errors Found
0x0000000A
IRQL_NOT_LESS_OR_EQUAL
Likely Cause
A kernel-mode process or driver attempted to access unpaged memory at an interrupt request level (IRQL) that was too high.
Actionable Fix
Update or roll back recent device drivers. Check for hardware compatibility. Run Windows Memory Diagnostic.
Kernel Level Halt
0x0000001A
MEMORY_MANAGEMENT
Likely Cause
A severe memory management error occurred. Usually indicates failing RAM sticks, mismatched memory, or corrupt page files.
Actionable Fix
Run memtest86+ overnight to test Physical RAM. Increase virtual memory. Update BIOS.
Kernel Level Halt
0x0000003B
SYSTEM_SERVICE_EXCEPTION
Likely Cause
An executing routine transitioned from non-privileged code to privileged code incorrectly. Often graphic driver related.
Actionable Fix
Update your GPU drivers explicitly. Disable third-party antivirus temporarily. Run 'sfc /scannow'.
Kernel Level Halt
0x00000050
PAGE_FAULT_IN_NONPAGED_AREA
Likely Cause
Requested data was not in memory. The system looked for data in the paging file, but the area requested was marked as nonpaged.
Actionable Fix
Check RAM for faults. Ensure you aren't aggressively overclocking CPU cache. Remove newly installed hardware.
Kernel Level Halt
0x0000007B
INACCESSIBLE_BOOT_DEVICE
Likely Cause
Windows lost access to the system partition during startup. Often caused by changing SATA modes (IDE/AHCI) in BIOS, or failing SSD controllers.
Actionable Fix
Verify SSD/HDD connections. Change BIOS storage mode. Run bootrec.exe /rebuildbcd in recovery.
Kernel Level Halt
0x0000007E
SYSTEM_THREAD_EXCEPTION_NOT_HANDLED
Likely Cause
A system thread generated an exception that the error handler did not catch. Extremely common generic driver crash.
Actionable Fix
Boot into Safe Mode. Identify the crashing driver (.sys file) using BlueScreenView or WinDbg and update/remove it.
Kernel Level Halt
0x000000C2
BAD_POOL_CALLER
Likely Cause
The current thread is making a bad pool request. A driver tried to free a memory allocation that was already completely freed.
Actionable Fix
Almost always a buggy device driver. Avoid utilizing unverified peripheral hardware drivers.
Kernel Level Halt
0x000000D1
DRIVER_IRQL_NOT_LESS_OR_EQUAL
Likely Cause
A driver tried to access a pageable (or completely invalid) address while the IRQL was too high.
Actionable Fix
Identify network or graphics drivers. Very common with outdated Wi-Fi adapters. Update via manufacturer site.
Kernel Level Halt
0x000000EF
CRITICAL_PROCESS_DIED
Likely Cause
A crucial system process (like csrss.exe, wininit.exe) died or was forcefully terminated.
Actionable Fix
Run DISM /Online /Cleanup-Image /RestoreHealth. If recurring randomly during load, check SSD health via S.M.A.R.T.
Kernel Level Halt
0x00000109
CRITICAL_STRUCTURE_CORRUPTION
Likely Cause
The kernel detected that critical kernel code or data had been corrupted.
Actionable Fix
Remove aggressive virtualization or anti-cheat software. Check for failing RAM. Avoid invasive modding tools.
Kernel Level Halt
0x00000116
VIDEO_TDR_ERROR
Likely Cause
An attempt to reset the display driver and recover from a timeout failed.
Actionable Fix
Ensure GPU isn't overheating. Clean dust. Perform a clean wipe of Video Drivers using DDU in safe mode.
Kernel Level Halt
0x00000124
WHEA_UNCORRECTABLE_ERROR
Likely Cause
A fatal hardware error has occurred. This bug check uses the error data provided by the Windows Hardware Error Architecture (WHEA).
Actionable Fix
Major hardware failure warning. Usually CPU voltage instability (turn off overclocking/undervolting) or failing physical hardware.
Kernel Level Halt
0x00000133
DPC_WATCHDOG_VIOLATION
Likely Cause
A Delayed Procedure Call (DPC) watchdog executed, either because it detected a single long-running DPC, or because the system spent a prolonged time at an IRQL of DISPATCH_LEVEL or above.
Actionable Fix
Ensure SSD firmware is completely up to date. Common on specific NVMe drives with outdated controller firmware.
Kernel Level Halt
0x00000139
KERNEL_SECURITY_CHECK_FAILURE
Likely Cause
The kernel has detected the corruption of a critical data structure.
Actionable Fix
Check memory for defects. Ensure aggressive anti-virus or memory-hooking software isn't conflicting with OS kernel protection.
A lock tracked by AutoBoost was acquired while executing at DISPATCH_LEVEL or above.
Actionable Fix
Usually a Bluetooth or Wireless adapter driver flaw. Update peripheral drivers.
Kernel Level Halt
0xC000021A
STATUS_SYSTEM_PROCESS_TERMINATED
Likely Cause
The WinLogon or CSRSS subsystem process died fatally. The OS transitions into kernel mode and triggers a blue screen.
Actionable Fix
Usually corrupted system hives. Run System Restore from recovery. Run SFC /scannow.
Kernel Level Halt
0x0000009F
DRIVER_POWER_STATE_FAILURE
Likely Cause
A driver is in an inconsistent or invalid power state. Very common when waking from Sleep/Hibernate.
Actionable Fix
Update Intel Management Engine (IME) or ACPI drivers. Disable Fast Startup in Windows power settings.
Kernel Level Halt
0x00000024
NTFS_FILE_SYSTEM
Likely Cause
A problem occurred within ntfs.sys, the driver file that allows the system to read and write to NTFS drives.
Actionable Fix
Run 'chkdsk /f /r' immediately. Indicates heavy sector corruption on the primary Windows drive.
Kernel Level Halt
If this is the first time you've seen this Stop error screen, restart your computer. *** STOP: 0x000000FE (0x00000008, 0x00000006, 0x00000009, 0x847075CC)
