Our blog about what component of a motherboard is not considered to be a field replaceable unit. This can be used to replace the motherboard during a new build or simply replace it with a backup unit should it break. The post details the replacement steps required as well as the motherboard’s pinout and connections.</p>

The motherboard

<p>The motherboard used in this example is a Gigabyte GA-H81M-S2H motherboard. It has an Intel P4S800 CPU running at 3.4GHz. The motherboard has a total of four SATA ports. There is also an additional 6 pin IDE port on the motherboard. The motherboard has a 16MB ATI Radeon 9800 Pro AGP card installed on it.</p>

<p>The motherboard has a total of nine pin connectors. I have highlighted the ones that are not a field replaceable unit in red. The ones in green are not highlighted as they are only used for installation and do not need to be replaced.</p>

Pinouts

<p>The motherboard has a total of nine pin connectors. The motherboard has a total of nine pin connectors.</p>

<p>The motherboard has a total of nine pin connectors. There are three connectors on the left side of the motherboard. These are the motherboard’s power connector. The power connector is located on the motherboard’s left side.</p>

<p>As we all know, the modern motherboard consists of a number of field replaceable units (FRUs) which are soldered to the PCB. The PCB is the foundation of the motherboard and provides the electrical and mechanical connections between the various components on the motherboard. The FRUs are used to replace the various components that have failed. For example, a faulty CPU will be replaced with a new one, or a faulty graphics card will be replaced with a new one.</p>

Video card replacement

<p>There are two video cards on the motherboard. One is a PCI Express video card and the other is an AGP video card. The PCI Express video card is installed on the motherboard’s right side. The AGP video card is installed on the motherboard’s left side.</p>

<p>Besides the PCI Express video card, there are no other components installed on the motherboard. The PCI Express video card is installed on the motherboard’s right side. The AGP video card is installed on the motherboard’s left side. Besides the PCI Express video card, there are no other components installed on the motherboard.</p>

<p>The PCI Express video card has a total of six pins. The AGP video card has a total of four pins. The video card has a total of six pins. The video card has a total of four pins.</p>

(PCI)

<p>The motherboard has a total of three PCI Express video cards installed on it. The PCI Express video cards are installed on the motherboard’s right side. The PCI Express video cards are installed on the motherboard’s right side.</p>
