If there is a low voltage or disrupted current flow, some components may stop working. If it is not, you will need to replace the power supply. Ensure it is properly plugged in and that the voltage is set to the correct level. The first thing you should do is check the power supply. The power supply is the main component of the CPU that helps provide power to the parts for them to work. Lets get on with the VGA lights fixes but before we move ahead, check out this video for a clearer idea. If one of the components is outdated or does not work, the light would turn on. The compatibility of the motherboard and the graphic needs to be checked first. How to Fix the VGA Light on the Motherboard?īefore fixing the VGA, you should ensure that everything is working perfectly. To fix this issue, you must check your storage devices and see if there are any loose connections. Whenever a red light is lit for the BOOT, the Boot devices cannot be detected by the CPU. You are required to check if the card is correctly plugged in the PCIe slot and if the power connectors are perfectly placed. When the red-lit comes on for the GPU, the system does not detect the graphics card. The clamps that set the RAM on the places must be properly locked, and a clicking noise should come when appropriately selected. You must check your RAM and ensure that they are correctly inserted in their slots to fix this. If the red led on the motherboard turns on for the RAM, the system does not detect the RAM. 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. 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. It is the main component of the computer that is present in the center of the motherboard. Lets look at an overview of the different LEDs present on the motherboard for other components. This usually means something wrong with the video card or with the connection between the video card and the motherboard. One of the most common issues is when the VGA light on the motherboard stays on even when theres no video signal coming from the computer. The motherboard is an essential part of any desktop computer, and when it starts acting up, it can be pretty frustrating. Newer models come with several LEDs on the motherboard connected with different parts of the computer, such as the CPU, RAM, GPU, and Boot. Whenever the light is turned on, it is required to go through all the computer components to detect what is wrong. Older models mostly have one light on their motherboards. 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.ĭepending on the manufacturing year, motherboards may have multiple LEDs on the board for specific CPU components to detect the issue quickly. VGA lights on the motherboard are present there to indicate malfunctioning hardware.
