What Do The Lights On Motherboard Mean?

Most motherboards have LEDs or LCD displays that display error codes when something is wrong, or not functioning correctly.

In this article, we will look at what the yellow light on motherboard mean, and how to identify which component caused the problem based upon the meaning of the blinking lights.

When the motherboard collects errors, a series of LED lights will be turned on by it. This action is to remind you to check the conditions of computer. But this may be confusing for people who are not familiar with it. In fact, what do the lights mean?

Each color means the error description in different motherboards. When the light blinks, it has some feedback information for you about computer’s system state.

Often the meaning is written in a sticker on the motherboard, or even in the motherboard’s manual. The meaning of each light is not the same on all motherboards, which is why you need to check the manual of your motherboard to know the meaning of each light.

If you see a yellow light, it means there is probably something wrong with the RAM. The presence of the LED lights on the motherboard is a great way to recognize problems within your machine before they become a serious issue.

The meaning of the colors can best be understood by looking at the user manual that came with your computer. While you can use online guides to find out more about the lights on the motherboard, it is better to refer to the user manual as it’s undoubtedly going to be more helpful.

Motherboards have a few different lights by which they can show if there is an error or not but most of the time, the red light is another light that is going to be indicating that something went wrong with your motherboard.

Orange light on motherboard

To minimize confusion, if the orange light on your motherboard is blinking, it is normal but may also means there is an issue with your power supply. In the case of problem with power supply, replace your power supply with a new one that meets the requirements of your motherboard.

If the orange light is static, you likely have an issue with your RAM or one component isn’t properly connected to the motherboard.

The orange light blinks rapidly when the motherboard receives power and it is functioning correctly. This can be a solid light, a blinking light, or a flashing light.

A solid orange light means you have power, but the motherboard is not getting any other signals or receiving any input.

How to fix Yellow / Orange Light on the Motherboard?

The orange or yellow light on your motherboard may mean different thing based on the type of motherboard. It can be caused by a failing power supply, a malfunctioning motherboard, or excessive dust build-up around it.

Before you try any fix, read your motherboard’s manual to know what each light means.

Depending on what you see, try unplugging your computer and waiting for several minutes before plugging it back in again then see if you can get it running again. If not, you need to try the following.

Locate Your Problem

To find out if your motherboard is the cause, you can remove everything connected to it, starting with graphics and other add-in devices like storage devices and RAM.

Remove any case accessories that are attached to the motherboard and put on your computer with one RAM stick to see if the problem stops. This process is called troubleshooting.

If you see constant yellow or orange light again, your motherboard is likely problematic. If you find that there is no problem with these devices, then you should try the next solution.

Remove and Re-insert the RAM Stick

The orange light indication on your motherboard might indicate that there’s a problem with your RAM. Remove the RAM, and then reset it.

Some people may need to clean their RAM by either blowing into it or cleaning it with rubbing alcohol before putting them back into their respective slots. If you still have problem, try inserting the RAM into a different slot. If this doesn’t solve your problem, try the next solution.

Reconfigure Your RAM

If your computer keeps showing an orange or yellow light on your motherboard, check if there is any button near the light; press the button for a few seconds and the problem may be fixed. Pressing the button will reconfigure your RAM based on its setting.

If this does not fix it, try the next solution.

Change GPU Slot

To fix the orange light on your motherboard, you can try removing the GPU and re-insert it just like the RAM. However, if this still doesn’t work, you can try using a different PCIe slot on the motherboard.

Different manufacturers have multiple PCIe slots on their motherboards so that they can support several graphics cards.If this does not fix it, try the next solution.

Change PSU

If the orange light on your motherboard is lit, you will want to first check if the GPU fan and cooling fan are working. If not, this may require you to get a power supply which can provide enough power for the total system.

To check for this, you need the wattage of your entire system, which can be found by searching “total power usage” and “watt-hour”. If this does not work, try the next solution.If this does not fix it, try the next solution.

Update Your BIOS (Basic Input/Output System)

BIOS, short for Basic Input/Output System, is a program built inside your computer’s ROM (read-only memory).

It keeps a small amount of data in the motherboard ready to load and run the operating system and devices connected to it. When you want to update your computer’s BIOS, it means you need to flash the BIOS in your system.If this does not fix it, try the next solution.

What YouShould Do If Your PC Won’t Turn On?

If your computer won’t turn on, there’s a problem. The first thing to do is verify that everything was installed properly and look for incompatibilities.

Look closely at the motherboard manual for understanding the blinking lights.

You should also check your motherboard manual if you see blinking lights when your system boots up.

Problems with hardware and software can cause your computer to stop working. If you are having a problem with your computer not powering on, one of the first fixes to try is to make sure that it is actually getting the right amount of power.

It is common for cables to become loose over time, and some even get damaged. This can lead to power supply issues which in turn result in your computer not turning on. You should check for any possible damage or connection instability in the cable.


Seeing yellow lights on motherboard can be alarming sometimes, but it can be very useful if you use it right. You can easily identify problems with the hardware quickly if you know the meaning of those lights.
