电脑硬件故障的常用检查办法（Common inspection methods for computer hardware failures） Common inspection methods for computer hardware failures Master some basic computer maintenance detection method is the basic knowledge necessary to solve the computer fault, if you understand these knowledge maybe when your machine problems do not have to hold to the maintenance station, he will be able to solve, easy and convenient. tapping method This machine is in use process if sometimes normal and not normal circumstances, is often the result of splicing is not strong, and the poor contact caused by weld joints. Then use a small rubber hammer gently tap suspected faulty components, the observation error of the machine back to normal, the normal machine error, and the hand is the suspected parts by hand firmly, and then reboot, if the failure to eliminate. Cooling and warming method Sometimes the computer work for a long time or after the rise in environmental temperature, there is a fault, and shutdown, inspection is normal, and then boot again after a period of time, there is a fault, then you can use warming method to check the machine. Artificially elevated ambient temperatures are used to accelerate some of the less thermally stable components, and local heating is used to observe the waveform changes of the component to determine whether it is broken or not. The cooling method is a method corresponding to the rising temperature method, and also a good way to eliminate the components with poor thermal stability. measurement method The measurement method is a powerful method for the most common fault analysis and judgement, according to the measurement of different characteristic parameters, and can be divided into resistance measurement, waveform measurement method, common measurement tools is multimeter. Minimum system method Refers to the minimum environmental computer can run, namely computer runtime components within the host (at least to insert CPu, memory, graphics card, motherbo
