[0029] Figure 2 This is a flowchart illustrating a method for resolving a computer's inability to start normally, provided by an embodiment of this disclosure. Figure 3 This is a flowchart illustrating a method for locating a computer that cannot start normally, as provided in an embodiment of this disclosure. Figure 4 This is a flowchart of a method for resolving a computer's inability to start normally, provided by an embodiment of this disclosure. Figures 2 to 4 ,right Figure 1 The computer fault detection methods described in this paper will be further described.

[0030] Specifically, this disclosure provides a method for detecting computer startup failures and resolving or locating the problem of a computer failing to start normally, which makes it easier for users to resolve or locate the problem of a computer failing to start normally more efficiently and optimizes the user experience.

[0031] The motherboard is soldered and fitted with a digital display tube, a Flash chip and a microcontroller, and a log reading serial port.

[0032] After the computer is powered on, the Flash chip records the printing log information. The microcontroller reads the printing information and checks whether there are any errors in the printing information through a pre-set detection command. When the microcontroller detects an error, it outputs a signal to the digital tube, which then displays the corresponding error message based on the signal.

[0033] Users can locate faulty hardware based on the information displayed on the digital tube, and resolve computer problems by reinstalling the corresponding hardware and restarting the computer.

[0034] If the computer still malfunctions after reinstalling the hardware, an external device can be connected to the computer's log printing serial port to restart the computer and record log information. By reading the recorded log information, the cause of the computer's inability to start normally can be investigated, thereby locating the fault.

[0035] In summary, this disclosure presents a method for detecting computer startup failures and resolving or locating the cause of a computer's inability to boot normally. First, the Flash chip prints log information. The microcontroller analyzes this log information, identifying the fault location during the startup process by detecting the instructions within the printouts. Upon receiving a fault instruction, the microcontroller sends a command to the computer's motherboard digital display. Using pre-set error codes, the digital display shows nine different error messages (00-08), allowing the user to pinpoint the fault location and eliminate hardware-related startup failures. If reseating the hardware and restarting the computer does not resolve the issue, a serial port tool can be used to capture the computer's logs. By reviewing the logs for error messages during the startup process, the specific fault location can be determined.

[0036] This disclosure utilizes a Flash chip to print a computer boot log. A microcontroller analyzes the boot log, identifies the fault location based on the log content, and sends instructions to a digital tube display. Based on the error messages displayed on the digital tube, the computer hardware is reinstalled to resolve the computer's boot failure. When reinstalling the hardware fails, the log information printed by a serial port tool allows for precise fault location, thus pinpointing the cause of the computer's boot failure.

[0037] This method can be used to conveniently resolve or locate computer startup problems during computer use. When a computer fails to start, the information displayed on the digital tube on the motherboard can be checked to determine the location of the hardware fault corresponding to the code. Reinstalling the hardware and restarting the computer can resolve the startup problem. If the above methods are ineffective, a serial port tool needs to be installed on the computer's serial port to record the computer's log from startup to the fault location. By reading the log, the fault information of the computer's startup failure can be checked, and the fault location can be pinpointed, facilitating targeted repair work by technicians. This invention facilitates users in quickly resolving or locating computer startup problems, improves user experience, and saves users time and money when encountering computer malfunctions. By analyzing the log information printed by the Flash chip using a microcontroller, the microcontroller sends error commands to the digital tube based on the printed information. Based on the displayed commands, the corresponding hardware is reinstalled to repair the computer's startup failure. When reinstalling the hardware is ineffective, a serial port tool is connected to the computer, and the specific fault location is analyzed based on the printed information recorded by the serial port tool, resulting in a more efficient and faster computer repair.

The computer motherboard digital tube displays different error messages through pre-set error codes, so that the user can determine the fault location based on the error messages displayed on the digital tube, thereby eliminating the power-on failure caused by hardware reasons. The fault location determination module 503 is used to capture computer logs via a serial port tool and view the error information during the computer's startup process to determine the specific fault location when the computer still fails to operate normally after re-plugging and re-plugging the hardware device and restarting the computer.

[0039] In some embodiments, Figure 5 The device is also used to build a machine learning model based on historical fault logs; real-time acquired Flash chip logs and serial port logs are input into the machine learning model; the machine learning model outputs a root cause analysis and a fault probability prediction of the fault, wherein the root cause analysis is used to distinguish whether the fault is caused by physical hardware damage, driver conflict, firmware version mismatch or poor hardware contact; the fault probability prediction is used to assess the risk level of a specific hardware component failing during future startup and generate preventive maintenance recommendations.

[0040] In some embodiments, Figure 5 The device is also used to identify the layout of a computer motherboard through a camera connected to the computer or an AR application on the user's mobile device; in the AR display interface, the error codes of the digital tube or the analysis results of the serial port log are overlaid on the corresponding hardware locations on the actual computer motherboard in the form of highlights, arrow markings or 3D animations; the AR interface provides interactive troubleshooting guidance including demonstrations of the correct hardware insertion and removal methods, gold finger cleaning instructions and replacement compatibility checklists.
