Rendszernhiba

Rendszernhiba is a Hungarian term meaning "system error" and is used to describe faults that affect the functioning of a computer system at the level of the operating system, drivers, firmware, or hardware rather than at the level of user applications. It encompasses issues that prevent normal operation or lead to unexpected behavior, and it can be non-fatal (producing error messages while the system continues to run) or fatal (causing a crash, reboot, or kernel panic).

Common causes include hardware faults (defective memory, failing disk drives, overheating), firmware or driver problems, corrupted system files, resource exhaustion, and misconfigurations. Software bugs in system components can also trigger rendszernhiba, often manifested by freezes, hangs, or system-wide error dialogs.

Symptoms vary by platform but can include error messages, system freezes, blue screens, kernel panics, or automatic reboots. In diagnostics, administrators review system logs, such as event logs or kernel logs, run hardware diagnostics, and examine recent changes or updates.

Troubleshooting typically involves isolating faulty components, updating or rolling back drivers and firmware, repairing or reinstalling system files, restoring from backups, and ensuring adequate cooling and power stability. Preventive measures include regular maintenance, monitoring, redundancy, and adherence to tested updates.

Rendszernhiba is a broad category and is distinct from application-level errors, which are produced by user programs rather than core system software. In multilingual and regional contexts, the term is used similarly to describe system-wide faults.
