A computer mainboard with a fault diagnosis function

Abstract

The invention discloses a computer mainboard with a fault diagnosis function. The utility model relates to the technical field of computer hardware, comprises a bottom plate and a mainboard, a plurality of support legs are arranged at the bottom of the bottom plate, slots are respectively arranged at four corners of the bottom of the mainboard, inserting rods are arranged at four corners of the bottom of the mainboard and are matched with the slots for use, components are arranged above the mainboard, and a heat dissipation film is arranged above the components. According to the invention, thenormal operation of the circuit on the computer mainboard can be monitored; once the temperature is too high or the current is too large, an alarm is given, the fan is started for cooling, and when too much dust falls on the computer mainboard, an alarm can be given, so that poor circuit contact or other problems caused by too much dust are prevented, and the computer mainboard fault diagnosis device is very suitable for fault diagnosis of the computer mainboard.

Description

technical field [0001] The invention relates to the technical field of computer hardware, in particular to a computer motherboard with fault diagnosis function. Background technique [0002] Motherboard, also known as motherboard, system board or motherboard; it is installed in the case and is one of the most basic and important components of a microcomputer. The motherboard is generally a rectangular circuit board, on which are installed the main circuit systems that make up the computer. Generally, there are BIOS chips, I / O control chips, keyboard and panel control switch interfaces, indicator light connectors, expansion slots, motherboards and cards. DC power supply connectors and other components. [0003] At present, there are many components on the general computer motherboard, and the circuit connection relationship is relatively complicated. Once a component fails, it is likely to affect the normal operation of the entire computer motherboard, but the inspectors can...

Problems solved by technology

[0003] At present, there are many components on the general computer motherboard, and the circuit connection relationship is relatively complicated. Once a component fails, it is likely to affect the normal operation of the entire computer motherboard, but the inspectors cannot quickly detect the faulty component. Or the faulty circuit brings great obstacles to the repair of the computer motherboard. At the same time, the current in the computer motherboard is too large or too small, which will also reduce the service life of the computer motherboard. Therefore, a computer motherboard with fault diagnosis function is needed.
