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.
