How to Repair a Motherboard
The motherboard is the main circuit board in a computer and is also known as a printed wire board, main board, or system board. Some of the main components of the computer are attached to the board, so it is essential that the motherboard functions properly. There are some signs that indicate the motherboard is malfunctioning. Some of these problems can be quite easy to fix. In fact, as much as 70% of issues blamed on a motherboard have nothing to do with it. Motherboards are composed of a variety of different components. They include the CPU, chipsets, RAM, cache memory, and expansion buses. Knowing what the parts are and how to repair a motherboard is knowledge that all computer users should not be without.
Identifying Issues with a Motherboard
There are a number of signs that indicate the motherboard is damaged, and the user should be looking out for them. One of the best indicators that the motherboard is having problems is if the computer goes straight into BIOS setup when it is turned on. Other signs are if the user cannot see the CD ROM or hard drive on the computer and if the mouse and keyboard are either not working or work sporadically. Another sign is if the USB ports will not connect. Several components of the computer, including the sound card, may all stop working at once if there is a problem with the motherboard.Some of these problems have simple solutions, and might have nothing to do with the motherboard. They are listed and described in the chart below.
Problem |
Diagnosis |
Solution |
---|---|---|
No Power
|
There are several reasons the computer could have no power, including problems with the power cable itself or the power socket. If the system has no power at all, the fan in the power supply will not turn on. The power light will also not illuminate. | The computer user should check the power cable to see if it is unplugged or damaged in some way. The user can try replacing the cord if it is damaged. If the user thinks there may be a problem with the power socket, he or she should test it in another socket. |
Inoperative System
|
An inoperative system is signaled by the power indicator lights being on and the hard drive spinning. It may be caused by a number of factors, including the expansion cards not being in all the way, or a defective expansion card. | If the problem is the expansion card, the user can press down firmly on both sides of the expansion card to make sure it is securely in the slot. |
System Will Not Boot Up
|
The system may not boot up from the hard drive, or it may not even boot up from a drive. If it will not boot up from the hard drive, the hard disk may be damaged or the connector between the system board and hard drive may be unplugged. | The user should check the cable that connects the system board and hard drive. If the hard drive is damaged, a replacement may be necessary. It is important to back up a hard drive regularly, because if it malfunctions all the data may be lost. |
Error Message
|
There are a number of error messages that the user may receive that indicate motherboard problems. One of them says Sector Not Found error, which could have a number of causes. | If the user sees a Sector Not Found error, he or she should back up all data. Then, the user needs to reformat the hard drive and reinstall the operating system. |
Expansion Card Problem
|
If there is no power to the monitor after the user installed an expansion card, the card could be the problem. Usually, this means that part or even all of the system is inoperable. | The computer user should try to change the RAM address on the new card. The user can check the card's documentation to see how to change the pin settings. |
Invalid Configuration Error
|
If the user gets a screen message saying there is Invalid Configuration Error, or CMOS failure, then it probably has to do with incorrect information getting into the configuration program. | In order to fix this problem, the user should review the system equipment and make sure the correct information was used in the setup. |
Blank Screen
|
If the screen is blank, the monitor may not be hooked up to the computer or there may be no power going to the monitor. | The user should check the power connectors that go between the monitor and computer. Of course the user can also check to make sure the monitor is connected to the display card. If the screen happens to go blank occasionally, it may just be due to the screensaver. An easy way to fix this is by disabling the screensaver. |
Keyboard
|
There may be various problems with the keyboard, including certain keys not functioning or the entire keyboard not working. | If all the keys are not working, the keyboard may just be locked. However, if only certain keys are not working, the user may have to replace the entire keyboard. |
Parts of the Motherboard
The motherboard is the core of the computer and is home to a number of different components. Some of the various motherboard components include RAM, the CPU, cache memory, expansion buses, and chipset, all of which perform different functions for a computer.Part |
Function |
---|---|
CPU
|
The CPU, or Central Processing Unit, can be thought of as the brain of the computer. It is responsible for completing a number of processes, including mathematical calculations and carrying out program instructions. |
RAM
|
RAM, or Random Access Memory, is where data is stored when certain programs are being used. It makes the computer able to run faster because it does not require the computer fetch information from the hard drive every time it is needed. |
BIOS
|
Basic Input Output System is a type of software that controls the operating software. The BIOS acts as an interface between the hardware and operating system. It is also known as device drivers, or drivers. |
CMOS
|
The CMOS, or Complementary Metal Oxide Semiconductor, is a type of RAM that work even when the computer is turned off and prevents reconfiguration when the computer is turned back on. |
Expansion Buses
|
These provide an input and output pathway from the CPU to other device. These buses carry signals, such as power and data, between components. |
Cache Memory
|
This is a small piece of RAM that improves the performance of a computer by preloading information from the slower main memory and transferring it to the processor when needed. |
Chipset
|
This is a group of small circuits that help the flow of data between components. They connect a number of components including the CPU, secondary cache, and main memory. |
