This blog is an introduction to the major parts of a computer.

CPU -Central Processing Unite controls the entire system and it is metaphorically compared to a human brain as it is responsible for the arithmetic and logical functioning.

Chipset -A chipset(North/South bridge) is a mediator that communicates with the CPU and the memory and other internal hardware units.

RAM -Random Access Memory is a temporary storehouse of data which are written and read almost at the same time by the CPU. If the information is not save the information would be lost

ROM -Read Only Memory is another device that stores data and as its name says, the data are only read from the chip but not written. It is a non-volatile memory unit which means that the data will stay in the chip regardless of the power supply.

Keyboard – It is the main input which aids in inputting letters and symbols

Mouse – Hardware to control the cursor in a monitor by hovering over a flat surface and performs selection and moving tasks.

Printers and Scanners – Devices that help in printing and scanning. The uses and types change with every environment.

Webcams – Video cameras that stream live video during video chat or record video.

DVD drives – Drives that read and write information from a compact disk.

Graphic cards – Components that help in controlling and enhancing graphics.

How To Perform A Motherboard Repair

1.Check Your Monitor

Perhaps your screen is not powered on? Make sure to check that your video cable(VGA/HDMI) is properly connected and that any loose connections are not occurring through unplugging and plugging the cable back in.

2.Check Your Graphic Hardware

If you have a graphic card connected to your computer motherboard, take it out and plug in your monitor’s video cable into the motherboard and then restart your device. If your computer boots up with no issues, you have a damaged graphic card that needs to be repaired or replaced.

3.Check Your Internal Hardware

There may be additional hardware installed in your desktop computer. To operate suitably, a motherboard only requires the following: RAM, Processor, colling Fan, and powersupply-smps. You can try to remove the additional hardware devices to test if the issue. Once removed, you can turn on your computer and see if it boots normally. If it does, that mean there is a problem with one of your interior hardware systems. You can test each part to see which one needs to be repaired or replaced.

4.Check Your CMOS Battery.

Your computer motherboard issue may be that your CMOS battery is drained. To assess the battery, remove the CMOS battery then start your computer up again to see if the problem is solved.

5.Check Your Ram card

A common computer motherboard issue is that your RAM (random access memory) is dead, causing your motherboard not to work. If you happen to have two RAMs, test each by removing one and turning your computer on. If the RAM is indeed the problem, then you need to repair or replace the RAM card.
