So, the first thing you need to convince yourself is the video card. Most of us use discrete graphics cards, and also have a video card built into the motherboard. To avoid wasting your time, the first thing to try to boot your computer through the integrated motherboard, so you will immediately understand that the issue is your external graphics card.
If you perkknut cable from an external graphics card into the built-in, but your computer does not display the image, you must remove the external graphics card and reset the BIOS settings to the main video card in the BIOS is set to build-in video card. You can reset the settings by removing the battery, which is located on the motherboard. Ten seconds is enough, after that put the battery back.
If you have determined that the video card is the problem, then proceed to your external card and start with a visual inspection. The first thing to do is to check the capacitors, sometimes blown capacitors are the cause of all the troubles. If you notice at least one blown capacitor, keep in mind that it must be replaced.
In general, if the video card continues to rotate the cooler, but the video card does not work, then most likely it is about power. First you should check if you have extra power connected to your GPU. Extra power for discrete graphics cards looks like a small wire that goes from the card to the motherboard. Be sure to plug it in.
If the power is connected and all capacitors are alive, then all that remains is to take the card to the repair shop so it was tested and tested with various devices.

Thus, we have tried to give an answer to the question, what to do if the video card does not work, but the cooler rotates.
Old video card
Most of the above mentioned problems are also true for existing graphics cards which are no longer recognized by your computer for some reason. The only thing that can be immediately ruled out is a hardware mismatch, because together the equipment was working properly before.
- Drivers are broken. Installed software can work for years, but then fails after installing new software, updating Windows or for other reasons.
- No contact. Every month or year a lot of dust and dirt accumulates inside your laptop or desktop PC system unit. The penetration of the foreign particles on the pins can cause the absence of a correct signal.
- Malware. Some viruses and Trojans infect and disrupt the Graphics Adapter. Lack of antivirus and visiting doubtful sites increases the risk of infection.
As you can see, there are many possible causes of the problem. In order not to rush among them you can follow the sequence of operations described below.
The first sign of an unusable graphics card is the absence of any image on the screen when you turn your computer on. However, this can happen not only because of the graphics card. Malfunctions of the motherboard should be judged only after checking the functionality of the other computer components.
The first thing to do is to check if the monitor works. For this purpose it is enough to disconnect the cable coming from the computer and then press the power button. If the “No Signal” message appears on the screen, it means that the monitor is in good working order.
The motherboard is a modular device consisting of independent electronic components. If any of them are disabled, both the onboard and pluggable devices, including video cards, may become inoperable.
The easiest way to diagnose the motherboard is to remove the external graphics card and plug the monitor into the socket of the built-in graphics card. If the computer does not have a built-in card, you can check the motherboard by installing another video card. What to do if you don’t have a test tool handy? Alternatively, turn on the computer without a graphics card and pay attention to the following:
- If earlier the speaker beeped when you turn on the PC, but now it does not, perhaps the problem is in the motherboard or power supply unit malfunction.
- Another symptom is that the speaker emits not 1 or 2, but 3-4 or more beeps when turning on the PC. It may be caused by a faulty RAM, CPU or any device built into the motherboard. Judging by the number and sequence of signals, you can determine which device is malfunctioning. This information can be found in the technical documentation of the specific motherboard model and/or BIOS version.
- The computer is capable of booting the operating system even with the video card disabled (removed). Turn on your PC with speakers or headphones connected. If you have heard the “Hello” sound when starting the operating system then you will hear it this time too. If the greeting sound has not been heard before, wait for 1-2 minutes after turning on the computer and then press one of the character or alphabetic keys, e.g. “b”. A short “Exclamation” (Windows) beep will have to be heard in the headphones.
Determining the exact malfunction of your motherboard at home is almost impossible. All you can do is preventive maintenance of your computer. For this you only need basic skills in handling simple tools. During the preventive maintenance the contamination is removed from the surface of the motherboard, the electronic components connected to it, and the power supply, the heat sinks are lubricated with thermal paste, and the fans are lubricated with machine oil. These manipulations can be enough to solve various problems of your computer.
To solve both problems you need to remove the video card from the system unit, and then inspect its contact area for severe soiling. Even a marker trace can cause no contact. To remove contaminants safely, you can use a regular eraser which effectively cleans the copper contacts. To clean the motherboard slot you can use a brush, which should be carried out several times along the connector, where the graphics card is connected. Once cleaned, place the graphics card in its slot until it clicks into place.
Incorrect BIOS settings
The settings stored in the BIOS firmware determine which of the video cards connected to the computer will be the graphics card by default. Also in the BIOS you can manually set which data bus the motherboard will use to work with the video card.
The problem with the incorrect BIOS settings is usually encountered by users whose computers have a built-in graphics card. If you connect an external graphics device to the motherboard, the computer keeps sending a video signal to the embedded graphics card without realizing that the user has installed an external device. Follow these instructions to fix it:
- Remove the reconnected video card and plug the cable from the monitor into the video jack on the motherboard.
- Turn on your computer and enter the user interface BIOS, for which you need to press one of the special keys (you can find out in the documentation to the motherboard) immediately after you turn on your PC.
- Next, you need to find the section with the settings of the devices connected to the motherboard. There are many variations of the names of this section. “Advanced BIOS Features”, “Configuration”, “Advanced Setup”, etc.д. (should also be listed in your motherboard documentation).
- Here you need to find the item for adjusting graphic device parameters. “Primary Display”, “Graphic Device”, “Graphic Configuration”, “Internal Graphic Device”, “Init Display First” and other options.
- Press the Enter key on one of these items. Usually BIOS prompts you to choose which data bus to use for the video card. If the graphics card is intended to connect to a PSI-E slot, you need to select that bus. It can be designated in the settings as “PSI-E”, “PSIE”, “PSIEx”, etc.д. There are also related options, for example. “PSI/PSIE/AGP”.
- Select the desired option, then press “F10” to save your changes and restart your computer.
- Once the monitor screen goes dark you may shut down the computer by pressing the appropriate button or by unplugging it.
- Install an external video card and connect the cable from the monitor to its connector.
- Turn the computer on.
If your motherboard does not have an embedded graphic card, you will not be able to enter the BIOS setup. However, you can try resetting it manually:
- Locate a small (20 mm in diameter) battery on the surface of the motherboard. It serves to power up the BIOS when the computer is switched off.
- Unplug the power cord from the computer.
- Remove the battery, wait 3-5 seconds and replace it.
- The BIOS will be reset.
- Turn the computer on.
If all else fails there may be a more serious hardware problem.
Lack of power
Some modern graphics cards (mostly high-powered gaming devices) require a separate power supply for which they are designed with a special socket. It is easy to guess that one of the plugs of the power supply unit (PSU) of the computer must be plugged into it. And here a problem may arise. the power supply itself may not be enough to power the graphics card and all other devices.
This can be checked by disconnecting certain devices from the power supply, without which the computer will be able to boot at least to the initial boot screen. Such devices include hard drives, optical drives, LED indicators, as well as additional fans. All of these devices can be temporarily disconnected to try and start the computer.
If the PC has booted to the startup screen, the problem is identified. you need to buy a more powerful power supply.
The computer does not see the video card. what to do?
Powerful video cards are bought not only by gamers, but also by people whose profession or hobby is connected with the processing of graphic data. If the computer does not see the new video adapter, you do not need to go to the service center right away. You can try to solve the problem yourselves.
Computer doesn’t see the video card
Today we will talk about such a problem as: your computer stops seeing your video card!
Let’s look at almost all possible options, why this may be. Practically, because no one can really know (other than yourself) what is going on with your computer. In view of the fact that the computer is a complex device consisting of many small, and not very small, details. Every part, down to the smallest capacitor, plays a role in your computer’s hardware circuit. If any part fails, it affects something.
The most common reason why the computer does not see your video card is the lack of drivers. Remember once and for all, for video card, the best way to download drivers from the official website, according to the model purchased, or install directly from the disk, which was (if it was) included with your video card. Also pay attention for what operation system and what bit type of drivers you download. Of course they must meet the requirements of your system! It’s trivial, but not everyone knows about it.
Next, move on to the more complicated parts of why the computer can’t see your video card.
Often the reason why your card cannot be seen is that the graphics card is not properly locked in the slot. It happens quite often. Please note, if you use PCI-Express plug to connect your graphics card. Usually this connector has a latch which should click into place very snugly. If the latch does not click into place, it means that your graphics card is not seated tightly in the slot. Gently insert the video card into the slot, first from one side then the other! After that, snap the latch and boot the computer. When logging into the operating system, you should see a message that your video card found a new device. After that, you must proceed to install drivers.
The next thing, because of which your video card is not visible to the computer is an outdated Windows and BIOS. Let’s start with the first obsolescence option.
Your Windows operating system must meet all of your graphics card requirements. If it says in the specs of your graphics card that it only works with Windows 7 and above, and only the 64-bit variants of Windows 7, then you must have Windows 7, Windows 8, or Windows 10, not Windows Vista, Windows XP, etc.д. over your operating system must be 64-bit only. You can check the bit depth of your operating system in the Control Panel, in the System!
An outdated BIOS can also be the reason why your computer cannot see your video card. If your BIOS version is very old it might not know about these newer, fancy video cards. The only way to fix this problem is to update your BIOS. Also pay attention to your BIOS settings, maybe the reason why the computer does not see the video card lies in them.
The extreme case, because of which your computer does not see the video card is a malfunction of the video card itself, or of the slot where you install it. Try to install your video card into another motherboard slot, if you have one, and also try to install another video card to check if both the slot and your video card with which you have problems are working.
So, we have considered almost all the cases in which your computer may not video card. Why is it practically? Read at the beginning of the article! And don’t forget to check our site periodically for updates every day!
Removing old drivers
First you need to remove all previously installed video drivers, to avoid conflicts between different versions of the software.
- Open “Device Manager”. Where to find it on Windows XP/7/8/10 is described here;
- Find the video adapter;
- Right-click on it and select “Properties” in the context window;
- Go to the “Driver” tab and click “Uninstall”;
Now the old software will be uninstalled. In some cases, the system may prompt for confirmation, so you will need to confirm your action. After that it is recommended to reboot the computer.
It should also be said that sometimes you need to uninstall the software, which was installed at the time together with the utilities for the graphics adapter. To do this, you will need to:
- Open “Control Panel/Programs and Features”.
- If your computer is equipped with AMD Radeon video card, you need to uninstall all programs related to Amd Catalyst.
- If your video card is nvidia geforce, remove files related to NVIDIA.
This way you will get rid of unnecessary programs.
Some more quick and efficient ways to uninstall are described in this article.
How to fix the problem?
Doctors say that the best way to cure a disease is to prevent it. The following rules will help you to prevent video adapter malfunction:
If you can not avoid the breakage, never turn to “homemade” methods of repairing graphics cards. This you can only worsen the situation.
Computer Repair: Fix No Display For Integrated Graphics
In professional conditions the repair algorithm is as follows. If the communication between the graphics card and the motherboard master restores the contact pads, thereby eliminating the problem. If the structure of the video chip is damaged or its contact with the chip is broken, the only solution is to replace the chip or graphics card in general.
Service will quickly and efficiently fix the problem of any complexity. Do not torture your video card, trying to fix the malfunction yourself. turn to the masters of their trade!
Your computer doesn’t see your discrete graphics card
This problem is often encountered by those who have reinstalled operating systems, when an error occurred during installation. The solution is possible if you reboot your OS, or boot from Livecd.
Another solution is possible when you uninstall all drivers which mention Nvidia, disable the folder with the name Nvidia. Clean registry. Disable Internet, antivirus, reboot and install drivers again. BUT if the proposed manipulations don’t help, you have to apply to a service center. There will help to solve repair and tuning problems.
The most popular problem related to this component is when the computer doesn’t see the video card in the device manager. The proposed solutions will work for Nvidia, AMD Radeon and other video cards.
