3 , plug Law
 
The reason pc failure of many systems , motherboards own fault , i / o bus failure , failure can lead to a variety of card system is not functioning properly . Using simple plug repair method is a method in motherboard failure or i / o devices OK. The way is shut down to remove the plug-in board -by-block , pull out a board on each machine running boot observed , once pulled out a piece of the normal operation of the motherboard , then the cause is that the plug-in board failure or the corresponding i / o bus slots and load circuit faults. If you pull out all the plug-in board is still not normal after system startup , then the fault is likely on the motherboard .
 
Another method is to plug meaning : some chips , boards and slot is bad , these chips , boards re- inserted correctly after removing the computer component failures can be solved by installing improper contacts .
 
4, the exchange
 
The same type of plug-in board , consistent with the way the bus , the same function plug-in board or chip mutual exchange of the same model , based on changes in symptom judgment failures. This method is easy to swap the maintenance of the environment , such as memory self-test error , exchangeable same memory chips or memory to determine the fault location , fault -free exchange between chips, fault phenomenon remains the same, if the exchange after symptom change , then the exchange has a chip is bad, the site can be further determined by block through the exchange . If you can find the same type of computer components or peripherals using the exchange method can quickly determine whether the quality of the component itself . Exchange method can also be used in the following situations: without the same type of computer components or peripherals, but have the same type of computer host, you can put the computer components or peripherals plugged determine whether it is normal on the same type of host.
