Error code 0xC000021A, also known as STATUS_SYSTEM_PROCESS_TERMINATED, is a Blue Screen of Death (BSOD) error that indicates a critical system process has stopped working unexpectedly. This often happens when essential system files like Winlogon.exe or Csrss.exe encounter problems.
This error can occur for various reasons:
- Corrupt system files: Damaged or incomplete system files can cause Winlogon or Csrss to malfunction.
- Failed upgrade: A problematic Windows update or an incomplete upgrade process can leave critical system files in a corrupted state.
- Hardware issues: Faulty RAM, a failing hard drive, or a problem with other hardware components can lead to the error.
- Third-party software conflicts: Incompatible or malfunctioning software can interfere with system processes and trigger the error.
If you encounter this error, you might see a blue screen with the error code 0xC000021A and a message like "Your PC ran into a problem and needs to restart."
