Disclosed are a method and device for detecting system failure, a computer device, and a storage medium. The method includes obtaining, when a system to be detected is powered on or off, a real-time voltage oscillation signal acquired by a voltage sensor arranged in a detection circuits of the system. The detection circuit is a circuit where a source and drain of a switching device in the system are located. A degradation trend of the system is determined according to the real-time voltage oscillation signal and a reference voltage oscillation signal corresponding to the detection circuit of the system. A failure detection for the system is performed according to the degradation trend of the system.
