How To Test A Motherboard Outside Of Case? – Full Guide

Are you planning to build a PC by yourself? But, you are unsure whether all the components are working correctly or not! This tutorial will help you. Today, we are going to tell you how to test a motherboard outside of case or how to test the parts outside the case. Stay tuned to know the details!

If you test your motherboard and all the other components outside the case, then you can make sure that all the parts are working fine without any struggle. But in case any of the components or parts are not working or they are a defective product or faulty component, then you can simply exchange that from the manufacturer company before building your PC.

How To Test A Motherboard Outside Of Case?

Your goal is to test the motherboard and enter it into its motherboard BIOS menu. Before starting the entire process you should read the motherboard user manual, don’t forget to touch a piece of metal to discharge the static charge from your body.

I. Install The Main Hardware Components

The very first thing you need to do is to unbox the motherboard box and place it in the motherboard cardboard box or on a piece of the cardboard itself. 

  • Now, bring the motherboard tray, CPU and place it into the socket properly and close the socket clip. After that, apply the thermal paste on the surface of the CPU and place the CPU stock cooler fan in the CPU cooler heatsink that comes with the CPU itself.
  • Then you need to insert the RAM sticks into the RAM slots of your motherboard.
  • After that, if you are going to use any dedicated GPU or video card, then install that also in the PCIe slot properly.
  • You don’t need to connect any kind of storage drive like the SATA 2.5-inch drives or the M.2 storage device because we will just enter it into the BIOS menu.

II. Connect The PSU To The Motherboard:

The very next thing you need to do is to place the PSU near the motherboard and connect the 24 pin ATX power pins connector to the respective place in the motherboard. Then you will also find an eight-pin CPU power connector just beside the socket; connect that also. If you have a dedicated graphics card, then connect it with the PSU also to check the power connection. 

III. Connect The PSU With The Main Power Supply:

Now, if you are done with all the connections to the motherboard, then the next step is to connect the power cables with the main power supply to the PSU or Power Supply Unit with the wall outlet or wall socket.

IV. Connect the output device: 

What we have done here is mainly to check that if we can enter into the BIOS menu or not; for that, we need a monitor. So, connect your monitor to the HDMI or DVI-D port, or if you have a dedicated GPU, then connect to it. After that, connect the monitor to the power supply. To navigate into the BIOS menu, you need a keyboard because you have to press the function key (most of the time). So, connect the keyboard and mouse via PS-2 port or in the USB port of the rear I/O panel.

V. Jumpstart Your Motherboard:

Nowadays, most modern motherboards come with a dedicated power button or power switch for on-off. If you have that, then press it to start the computer. In case if you don’t have the power button, then don’t worry, you can also start your computer by just using a sharp metal object or a screwdriver head. So, take it and start your system if you don’t have that power button on the board.

VI. Enter Into The BIOS Menu: 

After press, the power button or jump-start in the motherboard, you can see, some of the LEDs will start to blink, and the CPU cooler fan will also start functioning. If you have a dedicated GPU in your motherboard installed, then the GPU’s fan will also start to move.

Now, if you can see something on the monitor, then try to follow the mentioned key to enter into the BIOS menu. After going into the BIOS menu, you will be able to check CPU temperature and also see the CPU and Ram capacity mentioned there. It means your system has already detected all of these and has started working properly. Now, leave it for a couple of minutes, and then you can turn off your system.

How to find the motherboard socket type?

You can simply check the motherboard manual book, or in the box itself, you will find the socket type. There is another way to find the description of the motherboard: For that, you need to search the model’s name in Google, and you will find socket details and all these things.

You can install the CPU-Z software in your system, and from that, you will also find the CPU socket details. It will work for the laptop also.

How to know how many fan headers a motherboard has?

If you want to know how many fan headers are there in the motherboard for that, you need to read the motherboard manual. Or, you can google the model’s number and find it on the official website. 

How do I know if my motherboard needs a BIOS update?

When you go to the BIOS menu, there you can see the BIOS version. After that, go to your motherboard company’s website support and find the exact model number of your motherboard. They will have the latest BIOS version for downloading. Compare the version with yours. If you have the backdated one, then download it. Many of the motherboards come with unique software from which you can also upgrade your BIOS.

In the case of laptops, each and every company or manufacturer has its inbuilt help center software; from that also, you can check if there is any BIOS update available or not.

Is there a way to test for a faulty motherboard without installing it in the computer?

You need to install the individual component like CPU and RAM sticks on the RAM slots and power supply cables to the PSU and a monitor to test the motherboard outside the case. After plugging into the power supply, if the motherboard BIOS menu comes, it means it is working fine. If it’s not and if you notice any error code then there is a problem with one of the components or the motherboard itself.
