How To Fix VGA Lights on Motherboard

VGA lights can provide some unwelcome distractions for computer users, but it is possible to solve this problem. If you want to use your graphics card in the dark or are just curious about how to fix VGA lights on the motherboard, then you’ve come to the right place!

What causes VGA Lights to go out on a motherboard?

There are a few potential reasons why VGA lights on a motherboard might go out. One possibility is that the motherboard has gone bad and needs to be replaced.

Another possibility is that something in the system is interfering with the VGA signal, causing it to stop working. Here are some of the most common causes of VGA lights going out on a motherboard:

1. Bad Motherboard – If the motherboard itself is bad, it will likely cause all of the other components in the system to fail as well. It’s important to replace a bad motherboard if one becomes available because it will make fixing any other issues much easier.

2. Graphics Card – If the graphics card is not properly connected or configured, then it could be causing problems with the VGA signal. Ensure all cables are appropriately hooked up, and there are no obstructions between the graphics card and motherboard.

3. Power Supply – A power supply can also interfere with the VGA signal. Ensure that it’s properly plugged into an outlet and that its cables are not twisted or kinked. Also, check to see if anything is blocking any cables from reaching their destination in the system.

4. System Board – If something is wrong with certain parts of the system board, then it could be causing problems with the VGA signal. This includes things like broken connectors or damaged chipsets. In most cases, replacing just part of the system board will fix the VGA issue.

What are the symptoms of a faulty VGA Lights chip?

If you own a computer with a VGA graphics chip that’s not working as it should, there are likely some symptoms.

The most common problem is that the computer won’t be able to display any graphics – whether it’s a simple message on the startup screen or a complex image in an application. Sometimes, the computer may just default to displaying text instead of images.

If your graphics card doesn’t seem to be working, there are also likely to be other problems with your computer.

For example, if you’re having trouble logging in or starting up applications, your computer may also be slow or unstable. In extreme cases, you may even see blue screens or other errors when you try to use your computer.

The best way to test whether your VGA graphics chip is faulty is to check for these symptoms and see if they occur on your system. If they do, it’s likely that the chip is defective and needs to be replaced.

How can you tell if a chip is faulty?

If you have a Graphics card, monitor, or another device that uses a VGA connection, and the lights on the motherboard are not working, there is a good chance that the chip inside the graphics card is faulty.

When you turn on your computer and see only a black screen with some white text or lines moving around (a “flickering cursor”), there might be something wrong with your video card.

If you’re using an older graphics card or don’t have any other display devices connected to your computer, the problem is most likely with your motherboard.

First, remove the video card from your computer to check if your VGA chip is faulty. If you don’t have one, find a replacement video card online or at a hardware store.

Next, connect one end of an old VGA cable to the video output port on the back of your computer (usually blue) and connect the other end to the back of your new video card.

Turn on both computers and see if you can see any images on either screen. If not, your motherboard might be defective and need to be replaced.

How can you fix a faulty chip?

If your motherboard has a faulty VGA chip, you can fix the problem by replacing the VGA chip. This is a relatively straightforward repair and shouldn’t take more than an hour or two to complete.

To begin, you’ll need to remove the motherboard from your computer. If you don’t have a removal toolkit, you can use a Phillips head screwdriver to remove the screws that hold it in place. Once the motherboard is free, unplug all of the cables and set them aside.

Next, you’ll need to locate the VGA chip on your motherboard. It’s likely located near the CPU or RAM slots.

If it’s not located near any of these ports, look for a small board with several ports – this is likely the VGA card. Once you find the chip, flip it over, so its flat side is facing up, and unscrew its four screws. Be sure not to lose any of the components attached to it!

Once the VGA chip is free, slide it out of its socket and replace it with a new one. Reattach the correct cables and re-install the motherboard in your computer. You should now be able to see graphics on your screen again!

Frequently Asked Questions

Why are the VGA lights on my motherboard not working?

This could be due to a few things. If your computer is more than a year old, it might not have the latest video card or motherboard and, therefore, might not have support for the VGA interface. Also, the VGA circuitry may be damaged if your computer has been damaged in some way, such as a power supply or motherboard failure. Finally, if your graphics card does not have its dedicated power supply (or if it’s using an outdated power supply that’s not powerful enough), then the VGA circuitry on your motherboard may also be unable to provide adequate power to run the graphics card.

Can I fix my VGA lights myself?

Generally speaking, there’s no easy way to fix VGA lights on a motherboard without proper technical knowledge and tools. In most cases, repairing or replacing a motherboard will be considerably more expensive and time-consuming than simply replacing the graphics card itself.


If you’re having trouble with the VGA lights on your motherboard, there are a few things you can do to try and fix the problem. First, ensure your graphics card is properly seated in the slot; if it isn’t, it will likely cause problems with your motherboard’s lighting.

You might need to replace your graphics card if that doesn’t work. Finally, you can try using a different power supply or jumper configuration to see if that fixes the issue. Thanks for reading!
