Main article: Computer cooling
Motherboards are generally air cooled with heat sinks often mounted on larger chips, such as the Northbridge, in modern motherboards.[5] Insufficient or improper cooling can cause damage to the internal components of the computer, or cause it to crash. Passive cooling, or a single fan mounted on the power supply, was sufficient for many desktop computer CPU's until the late 1990s; since then, most have required CPU fans mounted on their heat sinks, due to rising clock speeds and power consumption. Most motherboards have connectors for additional case fans and integrated temperature sensors to detect motherboard and CPU temperatures and controllable fan connectors which the BIOS or operating system can use to regulate fan speed.[6] Alternatively computers can use a water cooling system
instead of many fans.

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.
A computer owner should be aware of some of the common problems with the motherboard. This will make it easier for the user to identify and even fix some of these issues.

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.
These parts of a motherboard are vital to the computer functioning properly.


Checking the Motherboard

If the user thinks that there is a problem with his or her computer's motherboard, it may be a good idea to take a look at the component. In order to look at the motherboard, the user needs to unplug the computer and take the battery out if it is a laptop. The user should take off the computer's cover, which may slide off or need to be unscrewed. The motherboard is a large flat board toward the back of the computer with many wires and cords connected to it. The computer owner should look at the capacitors, which are tiny cylinders. These might be rusted, which would indicate that the motherboard could be damaged. The user should also keep a lookout for bent or broken components. Loose screws in the case should be removed because they may also cause problems. A user should be very careful when working inside the computer and avoid getting any dirt or liquid inside the machine. It is a good idea to work on a table and keep careful track of all the screws and small components.

Finding Motherboards on eBay

If it turns out that a computer user needs to replace a motherboard, he or she can search for a replacement on eBay. The first step is to go to the Electronics portal and then select the Computer, Tablets and Networking category. From there, you can go to the Motherboards category and browse around. You can also search for particular motherboards using keywords. If you want to purchase a Lenovo laptop motherboard,, type it into the search engine and look through the results that the site's search engine returns. If you are having trouble finding a motherboard or other component for your computer, you can try posting a description on Want It Now.. This will let the eBay community know what component you want to buy and a seller will contact you if they have the right motherboard.

Conclusion

A computer user should be aware of some of the basic indicators that there is something wrong with the motherboard. This includes the keyboard or mouse not working properly and the computer starting up in BIOS mode. There are a range of problems that can occur with a motherboard and some of them are easier to fix than others. For instance, there may be just a cable disconnected. On the other hand, the hard drive may need to be reformatted or the entire motherboard may need to be replaced. There are many reasons why a motherboard may not be working correctly, so a user should try to diagnose the problem by looking at the symptoms. The user may also want to open up the computer to check for obvious signs of damage. If a user is unable to fix his or her computer, then it should be taken to a specialist for proper repair.
