It is possible that after installing a dedicated video card in your PC you will notice that it does not give video. If this is your case, then we recommend you read this article with which you will learn Why when I connect the video card the PC does not give video? – Solution
What is a video card?
Have you ever wondered what a video card is and what is it for? A video card or also called “graphics card” is a component that is attached to the motherboard of a computer. The video card processes the data sent by the CPU or “Central Processing Unit” and converts it into understandable information that can be displayed by an output device such as the monitor.
Video cards use a GPU o “Graphics Processing Unit” that reduces the CPU load in order to increase the computer’s performance when processing 3D images.
What are the components of a video card?
The components of a video card are the GPU, the RAMDAC, and the GRAM. The GPU allows graphics processing and it is the most relevant component of the video card; while RAMDAC is a digital signal converter that produces the PC to analog signal that can interpret the output device.
For its part, GRAM is the graphics memory random access which allows the transport and storage of information in memory chips. Outside of the technical aspects, if you want to know what type of video card you have in your PC, you can easily use the device manager in Windows.
Why when I connect the video card the PC does not give video? – Solution
Sometimes when we connect a video card the PC does not give video. In this situation, it is important know the cause or origin of the failure because it will be a determining factor that will allow us to apply an accurate solution.
Next, we explain the possible causes why the PC does not have a video output when we connect a graphics card and the solution that we can execute against this problem.

Causes why a PC does not give video when connecting a graphics card
One of the causes that produces problems when you connect the video card and the PC does not give video it may be a wrong connection. The deterioration of the monitor, some failure in the PC, a problem in the video card or in the RAM memories.
Check the connection if the PC does not give video
If we want to use a dedicated video card in a PC, it is necessary to connect the monitor to the port of this component. Sometimes, we connect the monitor to the integrated card of the motherboard and for this simple reason the PC does not give video.
Test if the monitor works
The monitor may be faulty or damaged. To find out, try the output device on another computer to rule out this possible cause.
Check your PC
Check if the power supply is working properly. To do this, check if your fan is working, the CPU heatsink emits heat, the hard drive emits a slight noise when the system starts, and if the power button is not faulty.
In case the equipment presents any fault you can reset the bios. To achieve this, locate the “clear cmos” button on the ports panel or change the position of the jumper (located next to the battery if the motherboard is old) towards pins 2-3 for a few seconds and place it back on the pins. pins 1-2. On the other hand, you can choose to update the motherboard’s UEFI BIOS to its latest version in order to keep your computer in good condition.
Check RAM memories
If the video card that you have connected to your PC still does not give video, we recommend check RAM memories in order to detect if any of them are faulty. In this sense, install the RAM memories on another computer in order to rule out this problem. You can also change the RAM modules if these components are damaged.

Check the operation of the video card
Finally, check that the video card is inserted correctly into the PCIe slot. Install the component on another PC to see if it is healthy. Connect the monitor to the video port of the motherboard and if the PC gives video, then the video card may have a problem. If the component does not work, you will have to change the graphics card of your PC for a new one.
