At the beginning, this is my 2nd semester and i choose Research method for my course because i was not good at doing research . So i wanted to study research and my journey was good. I learnt many new things and mostly i got some experience regarding doing research. My tutor Dr Clare Atkins is such a nice person and she help me a lot and she motivated me to do my study. she helped me in every thing even i did some mistakes but she never got angry on me and she gave me apologize for that. and i want to thanks her for guiding me. she is such a cheerful tutor and i want to study some more subject. So at glance i want to thanks her for everything and this is our last blog for this session. for this blog, i want to share some important things which is research on “Motherboard”.
The motherboard is a printed circuit board of a computer and it is pre exist on the back side of the computer case. It allocates power to communication to the CPU, RAM and all other Hardware computer components.A motherboard is one the most important part of a computer among other part. It contains several types of components of computer, including CPU, memory, connector for input and output devices and so on. In addition to circuits, a motherboard contains a number of sockets and slots to connect the other components. Here are the sample photo of motherboard.
Motherboard components are below:
- Expansion slots (PCI Express, PCI, and AGP)
- 3-pin case fan connectors
- Back pane connectors
- Heat sink
- 4-Pin (P4) power connector
- CPU Socket
- Screw hole
- Memory slot
- Super I/O
- Floppy connection
- ATA (IDE) disk drive primary connection
- 24-pin ATX power Supply connector
- Serial ATA connections
- Coin cell battery (CMOS backup battery)
- System panel connectors
- Serial port connector
- USB headers
- Integrated circuit
- 1394 headers
Other motherboard components
Below is a listing of other motherboard components that are not shown in the picture above or were part of older computer motherboards.
- Cache memory

- Screw hole aka mounting hole
- Voltage regulator
- Voltage regulator module (VRM)
What was the first motherboard?
The first motherboard was consider to be used in the IBM Personal Computer, that released in 1981. At the time, IBM referred to it as a “planar” instead of a motherboard. The IBM Personal Computer and the motherboard inside it would set the standard for IBM-compatible computer hardware going forward.
How to Design MOTHERBOARD?
A motherboard pass the electrical connections by which helps the other components of the system communicate. Unlike a backbone, it also contains the central processing unit and hosts other subsystems and devices.
A desktop computer has its microprocessor, main memory, and other essential components connected to the motherboard. Other components such as external storage, controllers for video display and sound, and peripheral devices may be attached to the motherboard as plug-in cards or via cables; in modern microcomputers it is increasingly common to integrate some of these peripherals into the motherboard itself.
An important component of a motherboard is the microprocessor’s supporting chipset, which provides the supporting interfaces between the CPU and the various buses and external components. This chip set determines, to an extent, the features and capabilities of the motherboard.
How to replace your pc motherboard?
Replacing a PC’s motherboard will takes time, especially if you’ve never done it before. You could trip on any number of little hurdles during the motherboard removal and installation process.
Why we need to replace it?
It happens because sometimes components fail. Motherboards are no exception. I’ve fried many a motherboard thanks to bad BIOS flashes and failing of power supplies. Things happen, and sometimes those things can irreparably damage your motherboard.
But troubleshooting or replacing a motherboard is a lot of work. Before you start, you want to make very, very sure that your motherboard is not working.. Step one is using one of these handy troubleshooting flowchart to make sure your motherboard is truly the culprit. Assuming your motherboard is confirmed dead, it’s time to consider a replacement.
What to look for in a new motherboard
There are many motherboard manufacturers companies, but only two CPU vendors. The CPU is the core of your PC and so it follows that you need to select a motherboard that is compatible with your CPU, be it from Intel or AMD. Afterthat, make sure the motherboard you chose is compatible with your current (or new) processor. Both companies have multiple different processor sockets for their chips. For example, if you have one of AMD’s recent APUs, you’ll want to buy a socket FM2+ motherboard. Conduct a Google search for your specific processor’s socket type, then look for motherboards built around that socket. Next step is to check board’s size is the next consideration. This decision will be largely dictated by how big of a motherboard your computer case can accept. Moreover, is to decide on a brand of motherboard. Nowadays, motherboards are more alike than they are different. You should not expect to see major differences in performance, power consumption, or overclocking between similarly priced motherboards from different vendors. They do however differ in color scheme, I/O capabilities, and expansion slot layouts.
How to install a new motherboard in your PC
- Once you’ve selected a motherboard and have it in hand now it’s time to install it. But before we get into that remove’s your old motherboard.
- Start by powering down and disconnecting any cables attached to your PC, then open up the side of your computer’s case so that you can access the motherboard. You should have a record of everything that needs to be plugged in before you start disconnecting them.
- The big items like graphics cards and Wi-Fi cards can come out of your motherboard first. Then go for SATA or other interface cables that connect your SSD, hard drive, or optical media drive to your motherboard.
- Finally, it’s time to disconnect all of the power cabling plugged into your motherboard. On most motherboards there will be a smaller 8-pin CPU power connector near the top of the motherboard, and a much larger 24-pin ATX power connector near the middle of the left side of the motherboard. You need to unhook both of these connectors.
- It’s time to break out head screwdriver and remove the screws holding the old motherboard to the mounting points in your PC’s case. Save the screws—you’re going to need them again later.
- Your motherboard should now be freely floating in your case—pull it out. With the old motherboard free, you’ll need to remove its CPU cooler, CPU, and RAM so you can install it into your new motherboard. Be careful! Don’t force anything and accidentally break your pricey hardware.
- Once that’s done, it’s time to get your new motherboard in your PC. You pretty much just have to replace everything you just pulled out of your old motherboard.
- Install the CPU, CPU cooler, and RAM in your new motherboard, insert your motherboard’s I/O shield in the rear of your case, then place the motherboard into your empty case.
- Be sure to use your motherboard’s standoff screws so it doesn’t directly touch the case wall. If you forget to use your standoffs, you risk frying the motherboard when you power up your PC. (Some computer cases come with raised mounting points preinstalled.)
- Reuse the screws that held your old motherboard in place to secure your new motherboard. Follow this up by reconnecting the two power connectors (24-pin and 8-pin) that you removed earlier. Now plug the SATA cables back in and slot your expansion cards back into place. Double-check that all of the internal cables in your PC are connected correctly and that everything is seated firmly in place. Reconnect all of the external cables that were connected to your PC before you took it apart, and power it on.
- Your PC will probably reboot a couple of times as the motherboard adjusts to its new life. Then everything should be back to normal. If you run into problems getting your computer to boot properly after you’ve replaced your motherboard, contact your motherboard manufacturer or ask for help on one of the many computer building forums around the web.
With a new motherboard your PC should be as good as new—and hopefully a bit more stylish to boot.
At the last, I choose this topic because in few days i am going to change my friend motherboard and i will help him to do that. So i did research on how to replace motherboard and now i am pretty much sure that i can replace his pc’s motherboard. This is my second and last post for this session because i forgot to post my blog for last week. So i post two blog.
