You’re probably wondering what to do if the VGA light on the motherboard isn’t working. You’re not the only one who feels this way. This is a typical problem that many people have but don’t know how to fix.

Fortunately, you can take a few simple actions to repair the situation. We’ll explain what causes light to turn on, how to troubleshoot it and how to prevent the problem from happening again.

What is the VGA Light on the Motherboard?

VGA lights on the motherboard are present there to indicate malfunctioning hardware. If hardware, most commonly the GPU (Graphics Processing Unit), is not running correctly, the light will turn on and remain on until the error is fixed.

Depending on the manufacturing year, motherboards may have multiple LEDs on the board for specific CPU components to detect the issue quickly. 

Older models mostly have one light on their motherboards. Whenever the light is turned on, it is required to go through all the computer components to detect what is wrong. Newer models come with several LEDs on the motherboard connected with different parts of the computer, such as the CPU, RAM, GPU, and Boot.

The motherboard is an essential part of any desktop computer, and when it starts acting up, it can be pretty frustrating.

One of the most common issues is when the VGA light on the motherboard stays on even when there’s no video signal coming from the computer. This usually means something wrong with the video card or with the connection between the video card and the motherboard.

Let’s look at an overview of the different LEDs present on the motherboard for other components.

  • Central Processing Unit

It is the main component of the computer that is present in the center of the motherboard. If there is any problem with the CPU, a red light turns on the CPU, which indicates that the system is unable to detect the CPU.

There are multiple reasons for the light to be lit, such as the CPU fan is not correctly plugged in, the CMOS battery running out, and it needs charging.  

  • Random Access Memory

If the red led on the motherboard turns on for the RAM, the system does not detect the RAM. You must check your RAM and ensure that they are correctly inserted in their slots to fix this. The clamps that set the RAM on the places must be properly locked, and a clicking noise should come when appropriately selected.

  • Graphics Processing Unit

When the red-lit comes on for the GPU, the system does not detect the graphics card. You are required to check if the card is correctly plugged in the PCIe slot and if the power connectors are perfectly placed. 

  • Boot

Whenever a red light is lit for the BOOT, the Boot devices cannot be detected by the CPU. To fix this issue, you must check your storage devices and see if there are any loose connections. 

How to Fix the VGA Light on the Motherboard?

Before fixing the VGA, you should ensure that everything is working perfectly. The compatibility of the motherboard and the graphic needs to be checked first. If one of the components is outdated or does not work, the light would turn on.

Let’s get on with the VGA lights fixes but before we move ahead, check out this video for a clearer idea.

  • Power Supply

The power supply is the main component of the CPU that helps provide power to the parts for them to work. The first thing you should do is check the power supply. Ensure it is properly plugged in and that the voltage is set to the correct level. If it is not, you will need to replace the power supply.

If there is a low voltage or disrupted current flow, some components may stop working. Your system needs an adequate PSU to work efficiently. Various online Power Supply Calculators show the requirement of your system’s supply.

  • Checking the Hardware

Every hardware is interconnected with the VGA Light. If there is any problem with a single component, the light may turn on. It is recommended to remove all hardware one by one to determine where the problem arises.

After removing all the hardware, place each one of them one by one to see where the problem arises. 

  • Graphics Cards Placement

The graphic card needs to be appropriately placed. Otherwise, the VGA lights may turn on if loose on the PCIe slot. Therefore, it is recommended to remove the graphic card by removing all the cables connected to it and detaching it from the PCIe slot.

After removing the card, again re-insert it and check if it’s fixed correctly in the place. 

  • Turn On the PC Without the Graphic Card

Many systems run the Intel processor, and it has the capability of booting the system without any dedicated graphics card as it has its dedicated graphic card. If the PC runs fine without the graphic card plugging, you need to replace it to function correctly. 

  • Check for Damages

If your PC gets damaged from a fall or any other unforeseen circumstance, there is a high chance that the PCIe slot or the GPU may stop working as the motherboard would not detect it. The Graphic Card contains a connector, which, if it gets damaged, the communication between the motherboard and the graphic card may halt.

There are small delicate gold-plated lines on the connector, and even if a single line gets damaged, the communication will happen. 

Although there might be a chance that your gold-plated lines can get stained due to extensive use, it is recommended that you clean them properly with cotton and rubbing alcohol. Otherwise, it would need to be changed completely. 

  • Check For Any Stains on the PCIe

Fixing VGA lights on the motherboard is not a daunting task. However, there are many possible reasons for this issue, and some essential troubleshooting tips can help you resolve the problem. In this article, we will explore some of these solutions.

One of the first things you should check is any stain or dirt on the PCIe slots on your motherboard. If there is, then use a soft cloth to clean it off. Make sure that there is no accumulated dust around the video card and its ports. You can do this by using a compressed air duster.

If the video card is damaged in any way, then you will need to replace it. Consult with your hardware vendor to find out the exact model of the video card that is compatible with your motherboard.

  • BIOS Setting

The BIOS (Basic Input/output system) is the most important component for improving a computer system. It allows you to turn on or off the components connected to your motherboard. A change in the BIOS setting might result in errors. However, resetting the entire BIOS to its factory default can resolve this problem quickly.

There are various ways to reset the BIOS setting. The most common method is resetting the BIOS setting by directly assessing it and resetting it using the Complementary Metal Oxide Semiconductor, which stores the BIOS setting in a small device.

Another way is by resetting the BIOS setting through a CMOS Jumper. 

  • Updating the BIOS

Mostly the VGA Lights issue gets fixed after a BIOS update, as an old running software can malfunction after a given time. You can easily update the BIOS setting using the flash BIOS button on the Input/output Panel.

  • Check Everything

The first thing you need to do to fix the VGA light is unplug everything. There are different steps that you need to follow one by one. 

  • Reconnect the power cord
  • Check that the video card is seated correctly
  • Reseat the RAM
  • Replace the CMOS battery
  • Test the PSU

If all of those steps don’t work, it might be time to bring your computer in for repair. Problems with the solder joints cause many motherboard issues, which can only be fixed by a professional.

If your computer is still under warranty, you might consider sending it in for repair. Otherwise, you can try to fix the motherboard yourself, but it’s not recommended for beginners.
