Random Access Memory (RAM)

Motherboards have a red led light if the RAM is not inserted well into its slots. It means the system does not detect the RAM. 

To fix this issue, properly insert the RAM in its slots. Ensure that the clamps that hold the RAM are appropriately locked, and the clicking sound should be heard to ensure the RAM is inserted correctly.

Graphics Processing Unit (GPU)

The system not accessing the GPU. The GPU needs a good connection with the motherboard for it to be detected by the system. It should be firmly secured and plugged in properly.

Remove and reseat the GPU, check if the GPU is compatible with the motherboard, test the GPU in another system, and update the GPU drivers to fix the issue. 

You also need the card properly plugged into the PCIe slots and all the power connectors placed.


A red light can be lit when your system book does not detect some of your components, such as the hard disk, CPU and CMOS battery. 

Remove and reseat components like the CPU, RAM, and GPU, check if all cables are correctly connected, test if the PSU is working, and update the BIOS to fix the issue.

Easy Methods to Fix VGA Light on Motherboard

Before we jump into fixing VGA, ensuring every component is working properly is essential. You need to check the compatibility of your graphic and motherboards. The light will turn on if one of these main components is outdated.



That is done. Now it is time to use the appropriate methods to fix the VGA light on motherboard. The methods are simple, and they don’t need any technicality. 

1. Power Supply

The PSU unit is your computer’s main power source. If it is not working correctly, then VGA Light will remain on. To check if the PSU unit is working properly, you can use a multimeter to check its voltage. 

A low voltage reading will indicate a faulty PSU unit, which needs to be replaced. You should also check if the power switches and connections are working properly. 

If they are not, you should replace them as soon as possible. Also, more powerful PSUs (with higher wattage) are usually recommended for computers using multiple components. 

The current flow or power supply disruption can cause the VGA Light to remain on. It is important to check all connections and cables are securely attached. 

Getting a quality PSU unit that meets your system requirements is highly recommended. A high-quality PSU will ensure your system operates properly and avoid expensive damage in the future. 

It is important to remember that a malfunctioning PSU can cause serious damage to your system. So you should take the necessary steps to ensure it stays in proper working condition.

2. Graphics Card

The Graphics Card is responsible for processing and displaying graphics on your computer’s monitor. It is highly sensitive to power fluctuations and can be damaged if the PSU unit does not provide enough power. 

If you notice that the VGA Light is on, it could be a sign of a faulty Graphics Card. Connect your Graphics Card to a different computer with the same configuration to check if it works properly. 

If the light remains on after switching computers, the Graphics Card could be faulty and should be inspected by a professional. 

But what if you don’t have an extra computer to test? Don’t worry. You are trying to boot your system with only one component attached. 

Disconnect all other components from the motherboard and leave only the Graphics Card to see if it can boot up normally. 

3. Checking the Hardware

Hardware is the one that interconnects all the components and makes them run. Ensuring all connections between your motherboard, graphics card and PSU unit are firmly attached is important. This is how to do it like a pro:

  • Disconnect all the components from your system
  • Close-check each component to check if there is any damage
  • If none is damaged, it is time to reassemble them one after the other, but ensuring that you boot the system, each component is added
  • In the end, ensure all cables and connections are firmly attached
  • Try booting your computer

When you plug in the component and the light turn on, remove it and continue with the rest. This is the main culprit.

Hardware, like any other component, can go bad over time. If the VGA Light remains on, a component may malfunction. It is important to check all cables, connections and components for any damage or signs of wear. 

If you cannot identify the problem and every component works well, we should continue to the next step.

4. Remove the Graphic Card and Turn on the PC

Intel processors have dedicated graphic cards. This means they can turn on without the external graphic cards. Can you try this? Disconnect your graphic card and try to turn on your system. If the system boots up with dedicated graphic cards, it is time to buy a new one. 

5. Check for Damages

A fall or a bump in your system may have caused the VGA Light to turn on. If you think that is the case, check all components and cables for any damage. 

The motherboard cannot detect any PCIe slots or the gpu that has stopped working. You need to check the gold line plates on your connector because they enhance communication. The system will not detect the c if any single line is broken. 

Overextended usage of the connectors, dust, stain, and debris build-up. In this case, clean the cable or dust off the slot with a vacuum cleaner and see if it helps solve the problem.

6. Update Drivers and BIOS

The VGA light can remain on if your system’s drivers and BIOS are outdated. To check if this is the cause of the problem, download a driver updating software like Driver Easy, Driver Booster or IObit Driver Booster. Once downloaded, set it to scan for updates and if any are found, install them automatically.
