Is your computer display hazy? Do you think if your graphics card is dead?

Do you frequently see the message pop up of “corrupt graphics driver”?

If the answers to the above questions are “YES”, then your PC is in serious trouble, and so are you!! Let us first understand:

What is a Graphics Card?

A graphics card (a video card, display card, graphics adapter, VGA card/VGA, video adapter, display adapter, or colloquially GPU) is a computer expansion card that generates the video output feed to display devices like monitors.

An internal device is categorised as a type of display adapter, video card, or GPU (Graphics Processing Unit), designed to handle the visual data, rendering the information clearly at high resolution, vibrant, and in full screen.

A graphics card produces excellent on-screen imagery by calculating the graphic data with sophisticated graphic technology, features, and functions. It has a GPU and dedicated RAM that helps perform graphical processing. Image quality will depend on the GPU, and can be crucial for games and video editing.

A GPU is a specialized electronic circuit designed to manipulate and change data to speed up the building of images stored in a frame buffer which are meant to be displayed on an output display device. GPUs can be found embedded in devices such as mobile phones, personal computers, workstations, and game consoles.

In modern GPUs powerful compute cores handle graphics and image processing. Parallelism is the key here since this approach can be much faster compared to a regular CPU when you need to process massive amounts of data in parallel. A GPU could exist on an add-on video card or built into the motherboard of a PC.

GPU stands for Graphical Processing Unit, which itself is a specific component housed within a graphics card, and it’s the one carrying out the actual graphics processing. A graphics card is responsible for rendering images to your monitor. GPUs can also be confused with graphics cards but there’s a difference. A graphics card is smaller than the motherboard that you have ever seen; it is only a PCB with a processor, memory, and more.

GPUs come in two major forms: integrated and discrete

Integrated GPUs are built into the CPU (and generally not as beefy as a good discrete GPU).

Discrete GPUs are separate from the CPU and have more power than integrated GPUs.

Different components of GPU

There are different components that come into function for the efficiency of a GPU, such as:

1. Graphics Processor

The GPU, which is the key element of any graphics card does all the calculating. It’s an electronic circuit designed to change memory and speed up picture building on a frame buffer meant to be shown to a screen.

2. Video Memory

Video memory is special RAM that helps graphics chip process graphic data fast. That data is stored inside the RAM on the graphics card.

3. RAMDAC (RAM Digital-to-Analog Converter)

The RAMDAC retrieves data from video memory, converts that data into analog RGB signals, and sends them on the video cable to the monitor. It achieves this using a lookup table, converting the digital signals for different colors to analog voltages.

4. Cooling Device

Graphics cards produce a lot of heat, so they need a heat sink to prevent them from getting too hot. The cooling component may be a fan, a heat sink, or a combination thereof.

5. Board

The board is a Printed Circuit Board containing the component parts of the graphics card.

6. Connectors for Graphics Outputs

Graphics cards have output connectors like VGA, DVI, HDMI, and DisplayPort. It can connect your GPU to a monitor or any display device with the appropriate connector.

7. Driver Software

Driver is another name for “Device drivers” in common English. It’s an application that is responsible for translating the instructions and commands sent from an OS like Windows or Linux for the graphics card. It tells the GPU what to draw, and how to do it and also talks with monitors.

Now that you know what is a graphics card let us find out why it is so important in a computer:

Graphics Cards are essential components in any computer, but if your aim is gaming, video editing, 3D modeling, or Machine Learning; it becomes even more crucial. Graphics Card: Graphics cards are used to render images and movies; they can have a massive impact on application responsiveness, user experience.

Here are some of the reasons why a graphics card is so important for your computer:

Graphics Cards are essential components in any computer, but if your aim is gaming, video editing, 3D modeling, or Machine Learning; it becomes even more crucial.

Graphics card plays an important role

1. Gaming

Graphics Cards is vital to playing high graphics game and it’s the same for every other hardware in the system.

Modern games use a considerable amount of processing power for rendering complex graphics and a high-end GPU makes all the difference in a gamer’s experience.

For instance, a strong graphics card would let you enjoy your game titles at higher resolutions and with a higher fps value for an enhanced gaming experience.

2. Video editing

Graphic cards are also utilized for video editing. Video editing software relies on the GPU to speed up rendering of video effects and transitions. This can speed up video editing tremendously, particularly for intricate video endeavors.

3. 3D design

Graphic card is also used for 3D design and modeling tools. The engine uses CUDA for performing ray tracing on the CPU. However, most of the rendering is done using the GPU to render 3D objects and scenes in real time.

This enables 3D artists and visualizers to speed up the creation process with live previews of design.

4. Machine learning

GPUs have also found a place in machine learning applications. Machine Learning Algorithms can take advantage of GPU which allows them to run exponentially faster.

This has caused graphics cards to be a key component for machine learning applications, such as picture recognition, text understanding, and more generally, AI.

Now you know the importance of graphics cards, let us know:

How to check whether the graphics card is dead or not?

1. Make sure your monitor performs its task

The easiest way to check if your graphics card is dead is this. If your monitor goes black for no apparent reason, it may mean that the graphics card is simply not talking to the display at all. Perhaps this was due to a bad graphics card, or perhaps due to issues in the cable connecting the graphics card to the monitor.

To check this, connect your monitor to another video output port on your computer. If you’re using a laptop, then consider attaching the monitor of your laptop to an external display. If the monitor still shows nothing, the GPU is probably bust.

2. Attempt to connect your monitor to another port of the PC

If your computer has additional video outputs, try connecting the monitor to an alternative port. If you find that your screen shows something when plugged into another port of your monitor, this likely means it’s an issue with the port you were initially using with your video output connection. However, if the monitor still wouldn’t turn on even when connecting to another port, then the probability of the graphics card being damaged.

3. Try starting in Safe Mode

If you have a way to boot into Safe Mode, there’s a good reason to believe that your graphics card isn’t the issue. Safe mode means the basic driver is installed (Basic display driver). If it shows something within Safe Mode but does not within Normal Mode, it’s most likely that at least one of your drives is having problems.

Try updating your graphics driver or even uninstall and re-install it. If Safe Mode doesn’t get you anywhere, this might be caused by a faulty graphics card. In any case, here are some other potential explanations: hard drive issues, and OS problems.

4. Try running a diagnostic tool

Various diagnostic utilities exist to scan your video card for issues. Fur Mark and Unigine Heaven are a pair of popular examples. These tests will challenge your graphics card to its limits. With both of these tools, if you find any issues with your graphics card, it’s probably a goner.

If you aren’t familiar with using a diagnostic tool then online tutorials can provide guidance on usage. Contact your PC maker, or take it to a repair shop, for help.

If all these steps fail to solve your problem then only you need to approach to computer maker or computer repair shop.

Some bonus tips:

  •       Always make sure that your graphics card is properly installed.
  •       Find a graphics card that is compatible with your computer.
  •       Make sure you check the temperature of the graphics card.
  •       Always keep your graphics card drivers updated.

These are all the information that you need on graphics card usage and efficiency.

Hope it helps.
