What is Motherboard and How Does it Work

The motherboard is the most critical component of your computer. Almost every physical part of your computer, including the processor, GPU, RAM, and hard drive, is connected to the motherboard and allows them to communicate to perform the tasks.

Your motherboard will face any failure is quite rare as they are already passed through multiple tests. A computer’s motherboards is the foundation for most of the machine’s components, enabling complicated circuitry to be used without needing a complex circuit.

How to Test Motherboard: Different methods 

There are two main ways to test the motherboard’s operation. A physical inspection for motherboard hardware/capacitor loss and PC diagnostic tools may identify software faults.

Examining the Motherboard Visually

Open the panel of your computer using a screwdriver. It is not necessary to remove the motherboard from the PC box. Examine the capacitors and other circuitry components on the motherboard with a flashlight.

Check for the leaking of capacitors in the motherboard since this is most likely the cause of the motherboard’s malfunction. If you see any leakage or bulging of the capacitor, you must consult a computer mechanic to ensure accurate soldiering.

Tools for Testing the Motherboard

The self-test is the initial way to test the motherboard. If your motherboard is damaged, your computer will not boot, and you will get an error message in the BIOS menu. If necessary, you should upgrade your BIOS.

The motherboard includes several different hardware components. As a result, it will be necessary to test the operation of the Thode components.

Here are several tools for testing components on the motherboard:

Hot-CPU Examiner

A hot CPU Tester is a tool for testing the stability of a motherboard and its components. Specialists use the Hot-CPU tester defect track engine to examine the overall condition. This utility comprises modules that test each element of the motherboard. Only stable parts survive the test after being strained to their ultimate limits.

Advanced Sysinfo Tool (ASTRA)

Astra is a diagnostics and system configuration analysis instrument. It includes a challenging drive health condition checker that shows information about the CPU, motherboard, memory modules, BIOS, etc. You also get information on the device’s system hardware and operating modes. After receiving the findings, you can download the reports in several text formats

PC-Doctor 3

PC doctor is one of the most famous producers of scanning tools for Windows computers. However, this costs $25. The Windows-specific toolbox may be used to troubleshoot PC hardware issues and get comprehensive system and software utility information.

How to Test Motherboard without a CPU

If your motherboard is malfunctioning, your computer will experience several troubles. It consequently needs to locate the issue inside it to solve it. However, most individuals are uncertain whether the motherboard can be tested without the CPU.

Here are the steps for testing the motherboard without a CPU.

Position Your Motherboard Securely

When we begin testing, you must ensure that the motherboard is securely installed. For example, if it is contained inside a case, there is no cause for concern. However, if you have purchased a brand-new motherboard, you will be testing it outside of the casing and will need to secure it accordingly.

First, remove the foam or softer material used to cover the motherboard within the packaging. Next, put the motherboard on the board. Alternatively, the motherboard may be placed on its box, anti-static foam, or other cardboard material.

Ensure that the motherboard is NOT placed on a metallic or conductive surface. Your motherboard’s underside has several solder points, which must not contact any metallic or conductive exterior while powered up. It is a crucial safety precaution since it might damage or destroy your motherboard.

Connect The Energy Connectors

After you have securely installed your motherboard, connect the power connections. When you look at your power supply unit, you should see an 8-pin connection for your CPU and a massive 24-pin connector for your motherboard. There may also be a 4-pin connection, but it is for older CPUs, so disregard it.

Before you proceed, remember that motherboards and electrical components, in general, are highly delicate. To avoid breaking anything, you must use a careful touch. Insert the 24-pin and 8-pin connections with care.

Turn On the Power Supply Unit

After attaching the PSU to your motherboard, you must turn it on by plugging it into a wall outlet. Make sure the PSU is NOT positioned on a bare metallic or conductive surface, just as you would with the motherboard. To set your PSU on, you may use cardboard or anti-static foam.

Remember to ground yourself when working with electrical components, put on non-conductive gloves, and wear slippers. 

Turn On The Motherboard

When everything is plugged in and connected, it’s time to power on the motherboard to see whether it’s functioning. It would help if you first searched for the Power Switch Pins. They are often found on the front panel header on the motherboard. If you cannot locate them, see your motherboard’s documentation for instructions.

The Power Switch wire coming from your case must be connected to these pins next. The cable will resemble the one shown in the illustration. Click the power button on the casing to turn on the motherboard after connecting the wire.

If you were curious, it is only possible if the motherboard is enclosed in a casing. What if, as was previously suggested, I had set the motherboard on a cardboard box? To do so, bring a point next to your motherboard to utilize its Power Switch connection, or you may physically jump-start the motherboard.

The last choice requires some caution since it is a little complicated. Take a flat-head screwdriver, the smaller, the better, and lightly tap the two Power Switch Pins to manually jump-start the motherboard. In this way, turning on your motherboard won’t need a case. However, be careful not to touch any other pins as this might short them.

Is Motherboard Working?

After turning on the motherboard, beeps or LED lights indicate its status. Find flickering lights and beep Life means a functional motherboard.

The LED flashing pattern, beep length, and frequency indicate computer issues, including memory or CPU errors. You’ll get errors as you haven’t plugged anything in. Ignore them—they’ll be repaired when you develop your PC.

What if your motherboard has no internal beep speaker or LED lights? Even if it’s unlikely, there’s a solution. To avoid harm, turn off the motherboard. Connect a fan to the motherboard’s 3-pin SYS FAN1 fan header.

After plugging in the fan, restart the motherboard, and the fan should start spinning. Thus, it is likely dead if your motherboard has internal beep speakers or LED lights and does not turn on.

Key Takeaways

  • To test a motherboard without a CPU:
  • Put your motherboard safely on a non-conductive surface.
  • Connect the motherboard’s 24-pin connection to the CPU’s 8-pin connector.
  • To the wall socket, attach the power supply unit.
  • Please turn on the motherboard by manually starting it with a jumper or by connecting the Power Switch connection from the casing.
  • If you see any flickering LED lights or hears any beep noises, your motherboard are operating.


I’ve explained how to test motherboard in this article. Without a CPU, you may quickly test a motherboard and receive various positive results. However, even if you can turn on a computer without a CPU, you cannot start it. Therefore you cannot do any tasks without it. You may regularly test your motherboard to see whether everything is functioning correctly.

 However, a visual inspection might quickly reveal the circuits. Try the tools mentioned above to investigate the components and activities of the motherboard. You may use these methods to test your motherboard and determine if it is fit for usage. I hope the procedures above will enable you to test your motherboard and save your costly PC swiftly.
