Embodiment Construction

[0008] Please refer to figure 1 The preferred embodiment of the computer motherboard fault diagnosis device of the present invention includes a controller 10, a voice processor 20, a data storage 30, and a sound player 40. The input end of the controller 10 is used to connect to a PCI (Peripheral Component Interconnect, peripheral component expansion interface) bus port of the south bridge chip of the computer motherboard to be tested, and the output end of the controller 10 is connected to the voice processor 20 The voice processor 20 is connected to the data storage 30, and the voice processor 20 is also connected to the sound player 40. Before the diagnosis starts, a main processing program and a playback program are first burned into the controller 10, and the pre-recorded error warning voice data is burned into the data memory 30.

[0009] After the user turns on the computer under test, the controller 10 receives the power-on self-test data in the South Bridge chip by callin...

Abstract

The invention relates to a computer main board fault diagnosis device, which comprises a controller, a speech processor and a sound player, wherein the sound player is connected with the speech processor, the speech processor is connected with the controller, the controller is used to connect with a computer main board to be measured, after the controller receives power-on self-test data of the computer main board to be measured and locks, stores and decodes the power-on self-test data, corresponding speech addresses are selected, and an address call instruction is sent to the speech processor. The speech processor calls out corresponding speech data according to the address call instruction and sends the speech data to the sound player after the speech data are converted to simulation audio signals, and the sound player plays the simulation audio signals which are received. The computer main board fault diagnosis device is simple, convenient and visual, and users can rapidly and accurately find out the fault reason and positions of the computer main board, thereby timely clearing of fault.

Description

Technical field [0001] The invention relates to a fault diagnosis device for a computer motherboard. Background technique [0002] With the advent of the information society, people’s demand for computers is increasing. Computer motherboard diagnostic cards, namely POST cards (Power on Self Test), came into being under this situation. Its working principle is When the computer cannot boot the operating system, the screen is black, the speaker does not sound, etc., insert the motherboard diagnostic card into the expansion slot, and refer to the BIOS (Basic Input / Output System) of the computer according to the code displayed on the card. ) Type, and then find out the cause and location of the fault represented by the code through the quick look-up table of the code meaning of the mainboard diagnostic card. However, ordinary consumers or primary users are unlikely to be equipped with motherboard diagnostic cards, and the code representation is not intuitive for ordinary users. Summ...
