What this code can mean
Windows detected a memory-management-related condition. Drivers, system files and hardware may be involved; the code alone does not prove bad RAM.
Possible causes to investigate
- Driver or software issue.
- Damaged system component.
- Possible memory or hardware instability.
Safer troubleshooting order
- Record the code and recent changes.
- Disconnect newly added devices and check official driver updates.
- Back up data and use appropriate diagnostics if stable.
Check the stop-code pattern and recent changes
This stop code can involve memory management, drivers, system files or hardware, so it does not by itself prove that a RAM module has failed. Note whether it began after a driver, BIOS or hardware change. Back up important files and use supported diagnostic tools before changing firmware or replacing components.
Details to keep: Record the full stop code, any 'What failed' name, frequency, recent changes and results of any built-in memory diagnostics.
Use the code with the full message, Windows version, recent changes and diagnostic evidence. Back up important files before recovery or servicing.
Before applying a code-specific fix
Windows error codes can vary by operation and version. Match the complete message, Windows build and update or driver involved, then follow the diagnostic order on this page before attempting a disruptive recovery.
