The motherboard is a computer’s main printed circuit board onto which all hardware and peripheral components attach in order to function.
What is a Motherboard?
The motherboard also called a logic board in some devices, is the main circuit board of a computer onto which all the hardware components attach. Besides securing the PC components in place, the motherboard also distributes power and enhances communication among the electronics, thus ensuring the smooth running of your computer.
The motherboard ensures connectivity between the CPU, the RAM, hard drive (SSD or HDD), video card, sound cards, optical drives, ports, and expansion cards. So critical is the mainboard to your PC that without it, the computer won’t function. Similarly, when it’s on the fritz, your PC will show serious signs of system malfunction.
How to Check My Motherboard’s Model Number
Knowing how to check the model number of a PC’s motherboard finds use when you want to upgrade some components or maybe replace the entire baseboard. The model number makes it a lot easier to obtain compatible replacements. Besides component upgrades, you can also use this number to get your computer fixed remotely.
In such a case, the remote technician will just request the machine’s model number, and then he or she will figure out or recommend the best way to fix the problem on your PC. For a detailed description of how to check your motherboard’s model, read this article on What Motherboard do I Have?
Motherboards have a wide range of components, all of which work together to keep your PC running smoothly. While motherboard models vary with the PC brand, the actual components are almost the same.
However, it’s worth noting that some motherboards have expansion slots that allow for the attachment of other components, which further enhance the functionality of the computer. Be that as it may, here are some components found on the ASUS P6T Deluxe V2 motherboard:
Also called the processor or mini-processor, the CPU is responsible for executing program files by performing mathematical and logical calculations.
This chipset is tasked with the processing of high-speed electrical signals from the CPU, RAM, AGP, and PCI Express while also communicating with the Southbridge.
Another chip is tasked with the processing of low-speed electrical signals and relays the same to the CPU via the Northbridge. The name is associated with its location to the south of the PCI bus. The integrated hardware includes a network card, and a sound card, and a couple of other low-speed peripherals.
Also referred to as a RAM slot or memory socket. The memory slot allows the RAM (PC memory) to be embedded onto the computer’s motherboard. The majority of the motherboards have between 2 and 4 memory slots, and that determines the type of RAM used.
Links the motherboard to the sound card, network card, graphics card, and other critical components to provide key PC functionalities.
PCIe Express Expansion Slot
Provides a connection point for a network card, video card, sound card, SCSI, among other PC hardware components.
Conveys power to the power switch cable, hard disk indicator light, loudspeaker cable, among other connector cables.
System Panel Connector
Responsible for controlling the PC's power button, reset button, and LEDs. The system panel connector is also referred to as the system panel header, system panel connector, panel, or the front panel connector.
24-Pin Power Delivery Port
An extension of the original 20-pin power supply connector. The 24-pin power delivery port conveys power to the motherboard and its components. The 9th pin powers the entire motherboard.
The 8-Pin Power Delivery Port
Also called 4+4 pin auxiliary connector and it provides additional power to the CPU.
Rear Panel Connection Port
Provides a connection point for peripherals such as speakers, monitor, keyboard, and mouse.
USB Connection Slot
Used to connect USB devices such as a mouse, USB flash drive, keyboard, among others peripherals, to the motherboard.
Front Panel Audio Connection Pin
Provides a connection point for the front panel audio header for your headphone or microphone.
Jack SATA Connection Slot
Provides an interface for connecting a host bus adapter to your mass storage devices such as SATA hard drive or an optical drive such as CD-ROM.
IDE Connector Socket
The Integrated Drive Electronics (IDE) is an interface that links the motherboard to storage drives such as hard drives, CD-ROM, and DVD drives. IDE is often referred to as ATA or PATA.
Floppy Drive Connection Slot
Also referred to as floppy channel or FDD header, the floppy drive connection slot links the floppy drive to the PC’s motherboard.
Types of Motherboards
Motherboards are classified on the basis of their physical size and shape specifications (form factor), chipset, and type of processor sockets. For more information on the specific types of motherboards, check out this article.
Just like any other electronic component or gadget, your PC’s motherboard needs to be maintained to keep your PC working at its optimum. Here are some tips you may want to implement to keep your motherboard in perfect shape:
- Brush off the dust: it’s advisable that you get your PC’s motherboard cleaned of any dust once a month or after every 2 months. Check through to ensure all the components, including the fan, are brushed clean of any dirt or grim.
- Avoid chassis collisions and drops: sudden shocks following knocks, collisions, or drops will damage your motherboard.
- Carefully remove detachable components so as to clean the copper connectors. Remember to reattach them after the cleanup.
- In very humid surroundings, you might want to apply some desiccant on the chassis to prevent motherboard short-circuiting which could potentially damage your PC.
- Confirm that your CMOS battery is still working: that coin-like battery on your motherboard may be drained after years of use. That may lead to inaccurate PC date and other related system malfunctions.
- Ensure the fans are working: Dysfunctional fans will cause the motherboard to overheat thus damaging crucial components and potentially putting your PC on the fritz.
