When you buy a new computer, chances are you will need to replace the computer mother board. The motherboard is a small computer component that connects to your processor. Most often than not, the motherboard is the first component to fail in computers.
Due to an increase in physical damage, a computer mother board
fails more often than one would expect. Computer components are placed in a case with various insulating layers that protect them from damage. The very first layer to fail on a computer mother board is the dielectric layer that helps keep the components from shorting out.
Since heat is involved in computer operation, the dielectric layer will not conduct electricity. This will cause the computer to malfunction if the component becomes shorted out. The only way to correct this problem is to replace the entire motherboard.
If a defective board continues to fail after several replacements, it will be time to replace the entire motherboard. If you are replacing the motherboard, you should take great care in finding a reputable and experienced computer technician. There are many cases where technicians do not replace the mother board due to the expense and time involved. The fact is, when you buy a computer, you have an obligation to purchase a computer mother board that is of high quality.
When replacing the computer mother board, make sure the connector sticks are out of the way. After the computer has been removed from the case, you should turn the computer off and then remove the power cord from the outlet. Once the computer is turned off, you can find the two connectors near the power supply cord and it is recommended that you move the cord aside. The motherboard connector should be flush with the front face of the CPU heat sink assembly.
If the CPU heatsink assembly has been removed before the motherboard, you will have to disconnect the wires before you can disconnect the motherboard. Next, turn the computer on and make sure the power cord is not attached to the power supply anymore. You can check the voltage from the power supply by turning on the computer, connecting the power cord to the monitor and then turning the computer off. The voltage should read at least 120 volts.
With the computer powered off, you can connect a multimeter to the power connection on the motherboard.
The meter should read between 12 volts and 15 volts. If the voltage is not measured at this level, you will need to consult an expert technician.
While reading the voltmeter on the computer mother board, you will want to check to make sure that all the connections are secure. When the wires are disconnected, make sure the screw connections are still secure. You should also check the screw terminals for corrosion.
You should also check the mainboard connections for corrosion. If the board is scratched, you should replace the computer motherboard. You can buy a motherboard from your local computer store or you can buy a motherboard from a manufacturer that ships to your area.
Before you replace the computer mother board, you should always disconnect the computer from the power supply. Then, you should disconnect the monitor cables and turn off the computer. You should also remove the power cord and turn off the machine by unplugging the power cable.
Once you have done these things, you can now reconnect the wires to the electrical plugs.
- With the wire connections secured, you can reconnect the mother board and power connector.
- Whenever you are replacing a computer mother board, you should always have a certified technician come to your home.
- A trained professional will be able to replace the motherboard quickly and effectively.
