Yellow Light On Motherboard [Detailed-Guide]

What Does Motherboard Yellow Light Mean

A yellow light on the motherboard is an indication that there is a problem with your memory. if your PC has a strong yellow light, then that indicates a DRAM error while a blinking yellow light indicates normal HDD activity.

Yes, your PC has been doing great so far, but step into issues with your motherboard components, and all hell breaks loose. it happened to me a couple of times and after checking forums and reading manuals I have gotten a hang of the problem

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

What Do The Yellow Lights On MSI, Asrock, Gigabyte, and Asus Motherboard

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

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 a computer. But this may be confusing for people who are not familiar with it. In fact, what do the lights mean?

Often the meaning is written on 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 LED lights on the motherboard are a great way to recognize problems within your machine before they become a serious issues.

Solid Yellow Light On Asus Motherboard Meaning and Fix

The yellow lights on the Asus motherboard are part of the POST-state LED, which checks the DRAM during the booting process of the motherboard. If an error is discovered, the yellow LED will remain illuminated until the problem is resolved.

Troubleshooting and Fix

When I had this issue on my Asus Rog Strix B450-F Gaming AMD Ryzen 5 2600 Motherboard, when I installed  2 x 8GB DDR4 3000MHz – Corsair Vengeance, I solved it by re-seating the big power cable (ATX-24) that connects to the motherboard and then swapped the two RAM positions and everything worked perfectly.

Yellow light Blinking on motherboard

On some computers, a blinking yellow light signifies hard drive activity. When the hard drive is in use, the yellow light may blink in split-second intervals, whereas prolonged blinking indicates that the computer is constantly requesting information from the hard drive.

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

The yellow 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 yellow light means you have power, but the motherboard is not getting any other signals or receiving any input.

How to fix Yellow Light on the Motherboard?

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 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 yellow 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 a 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 a yellow 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 yellow light on your motherboard, you can try removing the GPU and re-inserting 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 yellow 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 that 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 You Should 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.

Conclusion

Seeing yellow lights on the 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.

But be sure to use your motherboard manual to easily identify the exact problem. Meanwhile, we hope that you enjoyed this article, feel free to leave us any comments below!
