All these fixes are explained in detail below:

1] Check the cable connections

Check the cable connections. The cables might be loose due to which the VGA light is turned on. You can also try connecting the cable to another port (if available). The VGA light on the motherboard also turns on if the cable connecting your graphics card to the motherboard is faulty. If possible, connect the graphics card to your motherboard with another cable. This will let you know whether the cable is faulty or not.

2] Turn on your monitor

In some computer models, the VGA light turns on when the monitor is turned off. Turn off your computer. Now, turn on the monitor and then the computer. See if the display appears this time.

3] Do you hear any beep sound?

Do you hear any beep sound? Motherboards of different computers make different Beep sounds when a hardware failure is detected. You can know the type of hardware fault in your computer by decoding the beep codes. The list of beep codes and their meanings is available in the user manual or you can contact your computer manufacturer support for more information.

4] Reset CMOS

Resetting CMOS can also help fix such types of issues. This action will also reset your BIOS settings to the default values. Follow the steps provided below:

Turn off your computer and unplug the power cord to avoid electric shock.
Locate the CMOS battery on your motherboard.
Gently pull it out of the socket.
Wait for a few minutes and reinsert the battery with the correct polarity.
Turn on your computer and see if the issue persists.

5] Clean your PC of dust

Dust can be one possible cause of this problem. If dust accumulates inside the ports, your graphics card will not be detected. Clean your PC (if it has not been cleaned for a long time). Completely turn off your computer before cleaning it.

6] Reseat the GPU

Make sure that you seated the GPU properly, so your motherboard detects it. Remove the GPU from the slot and reinsert it properly. It is better to clean the GPU and its slot before reinstalling it. Also, ensure you have installed the GPU in the right slot.

7] Set your BIOS to use the PCIe graphics

Certain settings in the BIOS can sometimes cause such issues. Open your BIOS settings and set it to use PCIe graphics. This will disable the integrated graphics card in the BIOS, and your computer will use the external graphics card.

Different brands of computers have different BIOS settings. Hence, you must refer to the user manual or visit the official website to learn how to access this setting in the BIOS.

8] Hardware fault

Hardware fault may also be one possible cause of this problem. The issue may be with your Power Supply Unit, the graphics card, or the motherboard itself. You can connect your graphics card to your friend’s computer to find out whether it is faulty.

The last resort is to get a professional help. Take your computer to a professional computer repair technician to resolve this issue.
