When repairing a computer motherboard, there are a variety of issues to consider. It is often possible to repair a motherboard to prevent the need to replace it, but there are circumstances in which the motherboard cannot be fixed. Before attempting to repair a motherboard, it is important to determine the cause.
The motherboard can fail if the computer overheats, if one of the memory chips goes bad, or if there is a power surge, especially due to one caused by lightning storms. If the motherboard is poorly made, then it is more likely to fail. It is important to check the motherboard to make sure it is in good shape, and to check the other hardware in the computer to make sure it is working and is not having an adverse effect on motherboard functionality.
When fixing a motherboard, it is important to prevent conducting static charges. After taking the side panel off the computer to get at the motherboard, be sure to make contact with a piece of metal that is not found on the computer. This will prevent static shock and further damage to the motherboard.
At times the motherboard can stop functioning if the plugs or other components become loose. To fix this issue, locate the power supply plug, disconnect it, and then reconnect it, ensuring it is secure. It is also a good idea at this point to inspect the other plugs to be sure they are connected tightly. If they have become loose, your motherboard may not be receiving enough power. If you are updating an old system by installing new add-ons, this may cause a problem as far as power, because your old motherboard may not be equipped to handle the power needs of these new components.
Occasionally pins in the motherboard can become bent. This issue can be fixed by turning off the computer’s power and using pliers or tweezers to bend the pin back into shape. If the pin is broken or it becomes broken when an attempt to bend it is made, then it cannot be fixed. A new motherboard will need to be purchased.
Sometimes the motherboard can become cracked if it is poorly made, or if it was not soldered properly. If the motherboard doesn’t have the right kind of support to ensure flexibility, it may crack when cards are placed into it. If this happens, the motherboard cannot be fixed, and it will need to be replaced.
