Abstract
In a system error detection method of a computing device, the computing device includes a graphics controller and a display screen. A frame of an image that is currently displayed on the display screen is obtained from a video memory of the graphics controller at regular intervals. The obtained image is compared with abnormal images of the display screen prestored in a storage system, to detect whether the computing device works abnormally. Characters of the obtained image are extracted when the computing device works abnormally. System errors of the computing device are detected by comparing the extracted characters with system error codes of the computing device that are stored in the storage system.
