So, today we will try to understand why the computer does not see the video card. Unfortunately, recently this error became common among many. Especially among those who prefer to constantly update the operating system. Nevertheless, you do not need to panic at once. After all, if the computer stopped seeing (or did not start at all) the video card, the reasons may not be dangerous at all. And you can easily cope with them without problems. So why is this phenomenon happening? How to deal with it?
Not until the end
The first and most banal option, because of what the computer does not see the video card, is its wrong installation. Actually mainly for stationary variants. After all, it is here that users try to replace themselves from time to time with their iron friend.
So, if your computer does not see the inserted video card, check that it is installed correctly motherboard. Most likely, you did not fully insert it. And so contact is simply not supported. As you can see, there is no reason for panic. It is desirable to simply remove the component, and then install it again until it stops.
Motherboard
Further, more serious cases are already happening. For example, a similar phenomenon can be caused by problems with motherboard. There are different options. For example, she simply broke down. Or the connector for the video card itself is damaged. To diagnose self-failure is unlikely to work. So if you suspect that there are damages to the motherboard, it's better to take it to a service center. Let the master confirm or refute your guesswork. In some cases, you can repair the damaged connector. If this can not be done, it is better to replace the card completely. 
Also, if you do not see the computer nvidia graphics card (or any other), it is worth paying attention to how old your "motherboard" is. The same goes for the card itself. Remember, an outdated motherboard will not work with a new "vidyuhoy", and vice versa. If suspicions are sufficient, replace the components, and then see if the problem is fixed. Most likely, the situation will be fixed without any problems.
Malfunction
It's too early to be happy. If you do not see your computer radeon graphics card or any other, but at the same time the equipment corresponds to each other, we can count on another rather unpleasant outcome. It usually takes place in the presence of old components.
It's about breaking the video card. If something is wrong with it, then the computer simply will not perceive it. Either options are possible, when the graphics card is working, it refuses to do it.
How to be? To begin with it is necessary to carry "iron" in repair or the service center. There you can try to fix the video card. If this is not possible, you will have to buy a new part. Try to pick it up in advance so that there are no problems with the motherboard. This technique will save you unnecessary trouble. And panic, including. 
Incompatibility
Why can not the computer see the video card? There are quite a few options, as you can see. But not all of them are dangerous. In addition to the cases already mentioned, there may be the most common incompatibility of equipment. Either the operating system.
That is, for example, you bought new video card. And your motherboard is not exactly old either. But when you try to connect, you fail. Most likely, the motherboard and video card do not match. Therefore, when buying and replacing the computer components, pay attention to which models and with which cards are combined. Otherwise, you just have to replace the hardware with a new one.
There is also incompatibility of the operating system with your hardware. Actually, basically for users who have installed themselves "Windows 10", or for fans of constant updates. All components of the computer have compatibility or incompatibility with this or that content. This item is prescribed in the characteristics of the device, but users usually do not attach importance to it. And in vain. This would save them from many problems. So, if the computer does not see the new video card because of incompatibility of the software, the second item will have to be changed. For what exactly? Look at the characteristics of your video card. There should be all written. In general, if you have "Windows 10", then you should not be surprised at the lack of work of some connected devices. This operating system is currently famous for its bugs and bugs, which do not allow you to work comfortably with software.
Drivers
Do you have a computer that does not see the card? Honestly, it is not always worthwhile to rush to check computer hardware, run around the shops and study the compatibility of equipment. Often it turns out that for one reason or another in the operating system there are no so-called drivers. This software allows the computer to see the connected devices and work with them.
So what if you have this problem? You can check it with the help of If you do not have any drivers, just download them for your operating system and then install it. After
Pay attention - it is necessary to search for drivers for each company and model of the video card, and also to select them according to your operating system. It's not so difficult - you can download all the necessary content on the manufacturers' websites.
Infection
The last outcome, which is only possible, is the infection of the computer. Viruses often become a huge problem for users. And it is because of them that your computer does not see the video card. This option is considered after you are convinced of the health of the equipment and its compatibility. 
Fix the situation without any problems - just treat the operating system with the help of antivirus. If this is not possible, you will have to perform a full reinstallation and then connect the drivers. And then enjoy the result. As you can see, not everything is as terrible as it seems. In general, the reasons that the computer does not recognize "vidyuhu" very much. If you doubt that you can cope with the problem yourself, it's better to just take the "iron friend" to the service center. There you quickly help to correct the situation!
Cases when the video card is not detected or the computer does not see it is a frequent occurrence among beginning computer users. To a greater extent, this applies to users, who often update system.
Solve this problem, often, quite simply. It may be faulty drivers, problems with BIOS, or generally incorrect connection. There are many reasons for this, let us consider the most common ones.
Incorrect card installation
ConnectorsThis reason is relevant for users of standard system blocks. If after replacing the video card the system completely refuses to see the controller, then first of all it is necessary check system unit .
Chances are that the card is not fully inserted, or it was inadvertently installed in the wrong slot. Most often this malfunction is accompanied by sound signals from the system unit, but sometimes the speaker is simply not installed.
In this case, it is necessary open block, remove the video card and check if it is properly installed. After, again insert controller into the socket and start the system.
Problems with the motherboard
This is a more serious malfunction. Without the availability of special tools here can not do and most likely will have to carry the motherboard to the service center.
But it is possible to carry out a number of actions and yourself:
- First of all, it is necessary reset BIOS, closing the necessary jumper on the motherboard or pulling out the battery for a few minutes.
- Using a flashlight, you can inspect the connector on the board to damage the contacts. Probably, something got between contacts (dust, insects, pieces of paper, etc.)
- Also it will not be superfluous check the graphics card on another computer. If it works, then it's in the motherboard.
- If the card is working, then you need to insert another video controller into the connector of your computer and check if the PC is being booted.
The last two items will allow localize breakdown. There may be options:
- The computer did not work with another card - the problem is motherboard
- The video controller did not work on another PC - the problem is map
The last option is when the controller is running on another PC, and your computer is working with another card. This is banal incompatibility of equipment. And there's nothing you can do here.
Card malfunction
Burned graphics card A very unpleasant situation is the breakdown of the card. It is complicated by the fact that it is not always possible to determine if the device is broken. However, if the controller not recognized by computers, artifacts appear when starting up, or the PC downloads the image from case to case, it is necessary to contact the service center where they can specify the reason.
Ownly, in this case, nothing will be done, because The device is soldered with microcontrollers that can be test only on special equipment.
Incompatibility of equipment
We mentioned incompatibilities a little higher, but here we will consider in more detail. Usually this problem is encountered when buying new equipment. A video controller can be simple incompatible with hardware: motherboard too the new or old, incompatible technologies and many other factors that must be taken into account when updating PC components.
Not always users pay attention to them, and in consequence receive a non-working PC.
Also, can occur software incompatibility . For example, older video controllers may not have drivers for Windows 10. This also works in the opposite direction - a new card can not earn on Windows XP, because drivers for this OS are almost not released.
Incorrect Drivers
Unidentified device The last thing to advise is check the driver. Often the device may not be recognized precisely because of damages or simple lack of drivers.
In the absence of drivers in the system, in Device Manager We'll see question mark with an inscription - . Perhaps this is your controller.
The best option is to find on the official website the driver for your video card model, download him and establish. If this did not work, then we return to the previous paragraphs. Perhaps your device is simply incompatible with the installed OS.
A number of PC users may encounter a situation where their video card does not appear in the list of Device Manager video adapters. Especially often this happens if there are two video cards on the computer - built-in and discrete, and the latter can suddenly "disappear" from the list of available modules on the PC. In this article I will tell you why the video card is not visible in the device manager, what the specificity of this dysfunction is and how to fix it.
In most cases, this problem occurs suddenly, and for no apparent reason. If previously two video cards were visible in the Task Manager, then after the appearance of the dysfunction only one (usually built-in) can be displayed, "unknown device" often appears, and the quality of the graphics drops to the base level.
All attempts to somehow detect the second video card or install drivers on it usually do not give results. If you try to install drivers for a missing discrete graphics card, the installer may signal that this card is not on the computer.
Why the video card does not appear in Device Manager
So, why is the video card not visible in the device manager? This can occur for the following reasons:
The video card disappeared on the computer - how to fix it
How can I fix a situation in which the video card is not displayed in the Device Manager of your computer? I recommend doing the following:
- If the problem occurs with the laptop - shut it down, unplug the power cord from the outlet, and then remove the battery from your laptop. Wait a minute, then return the battery and turn on your PC;
- Display hidden devices in the Task Manager. Go to Task Manager (click the "Start" button, enter devmgmt.msc in the search bar and press enter), click on "View" at the top, and select the option "Show hidden devices".
If the missing card is displayed - delete this device by right-clicking on it and selecting "Delete". Then try to reinstall the driver to your video card (you can use special programs to install driver level DriverEasy or DriverPack Solution).
- Try to remove all drivers for the missing graphics card, and then install them from scratch. To remove drivers to the graphics card, use the DDU (Display Driver Uninstaller) functionality. Download and install this program, reboot your computer to " Safe Mode"(Safe mode), start DDU.
Then select the driver for your missing card (NVIDIA, ATI, etc.), and click on the "Clean and Restart" option. The program completely removes the driver to your card, then the system reboots and tries to reinstall the driver to your graphics card (or do it yourself by downloading the fresh drivers to your card from the manufacturer of your graphics card (or your laptop)).
An alternative to DDU can be the use of another similar utility - Driver Fusion c with similar functionality and corresponding direction of action;
- Try to roll back the system to the point of recovery, in which problems with the "disappearance" of the video card was not observed. Click on the "Start" button, enter rstrui in the search bar and press enter. Then select the desired recovery point and roll back the system to a stable level;
- Check the system for viruses (Dr.Web CureIt !, Malware Anti-Malware and several others will help);
- Try to update your BIOS to the latest version (look for the latest version of BIOS on the site of the motherboard manufacturer of your PC).
Conclusion
If you are interested in how to return a video card to Device Manager, I recommend that you follow through with the entire set of tips I proposed above. The most effective option among the above is the complete removal of drivers to the missing video card using DDU or Driver Fusion, and then installing the latest drivers for the video card downloaded on the manufacturer's website. This method showed its greatest efficiency when correcting the problem I considered. "The video card is not visible in the device manager".
When installing a new system unit or replacing graphics cards, or bundled with various accessories, the computer may not determine the new one graphics adapter. Even if the computer before it worked stably.
Often the computer does not see the video card, although it is installed and even the driver can not find the installed device. Determine the cause, because of which the computer does not work in normal mode and decide how to fix it, you can and yourself. To solve such issues in the network, there are many sites with detailed descriptions production settings. But if the user is a beginner, is not very confident in knowing the structure and software of computer equipment, it is better to contact the service center for repair and maintenance of computers.
The simplest method is to test the system. This is a visual study of the computer and its layout and connections between the blocks. Examination of all blocks and connecting wires is made, their connection among themselves, whether or not there are any violations during connection.
If the video card does not work and everything is fine with the connections, turn it on and start the computer restart. If the result is negative after rebooting, you should check the BIOS ( basic system input / output).
Information that the computer displays on the monitor on reboot allows you to determine what actions you need to take to solve the problem with the video card. If the monitor has an inscription - Press DEL to enter setup - click, following the rules according to the instruction (on laptops, instead of DEL, you need to press F2 to enter the BIOS). Then go to the settings menu. In the settings we find the settings for the video card
- Graphic
- Video
- Display
Activating Video. VGA and Primary Display
Video card bus:
The F10 key stores the settings. After the reboot, we check how the video card is displayed in the list:
- Discrete card: AMD Radeon
- AMD Radeon Mobile Graphics
If the computer does not see the video card after that, you need to install it on another device to determine its operability. If the video card is working, you may need to replace the motherboard. During the test, different situations may arise:
- Overheating of the video card
- Starting an emergency restart
- Availability of viruses
- Obsolete drivers
- Defective graphics card
How to enable a video card on a laptop
Completion of laptops of some manufacturers, and now almost all, includes two video cards (video adapters), discrete and integrated, with the ability to automatically switch.
A discrete graphics card is an analog of video cards of a desktop PC.
An integrated graphics card is part of the processor or is on the motherboard.
Old versions of discrete ATI cards (AMD) are managed by the Catlyst Control Center utility.
Automatic switches require drivers. By setting the BIOS "Switchable" to the "Display Mode" menu.
How to disable the built-in graphics card
To disable the built-in video card when help with BIOS or with using Windows go to computer management and select - video adapters in the Device Manager tab. Click on the right button to disable it.
To determine which video card, in Google search we find the definition. To disconnect external adapter - We perform all the same operations. To turn off the integrated graphics card, go to the BIOS.
To go to BIOS, you need to boot Windows press: Del (for PC), F2 or F10 (for laptops).
In the settings responsible for the equipment, we have: Intergration Video, Primary Video Controller. Define Disable. But due to different BIOS versions, the names of the settings are different. You can disconnect the video card on the laptop the same way. The difference is only in BIOS versions.
How to switch video card
If the AMD processor and ATI / AMD graphics card for video card switching, you need to install the Catalyst Control Center utility on both video drivers by the drivers.
Switching to a graphics card is more automatic, depending on which program is used by the amount of information, a network or autonomous work is connected. The manual control is also performed by the Catalyst Control Center utility from the tray as well.
If the processor is Intel. ATI / AMD card, use Catalyst Control Center.
To automatically turn on or switch, the manufacturer's website offers a driver. We enter in the BIOS parameters Switchable in the menu Display Mode. BIOS download produced at the time of turning on or restarting. If the moment is missed, you need to wait until it loads windows program and reboot again.
The main hot keys are:
- F1- Lenovo
- F2 - main BIOS key (Aser, Asus, Samsung, Sony, Simens, Panasonic, Dell, Lenovo.)
- F10- Hewlett. Packard. Dell.
- Esc- Toshiba
Laptop does not see the video card
Similar situations, when the laptop does not see the video card, arise when the operating system is reinstalled windows systems. To solve such problems, you must first remove all the drivers installed earlier so that the program does not conflict with the newly installed software. In the manager of downloads we find the video card, right click on the (properties). On the Driver tab (delete) and OK.
To uninstall previously installed programs with video card drivers. On the control panel open (Programs and components).
For cards AMD Radeon, remove everything related to AMD (for older video card models - ATI Catalyst).
For the video card nVidia - remove everything where nVidia is mentioned.
This is also true for Intel HD Graphics.
To solve the issue of installing video card drivers, you need to go to the manufacturer's website to find your device and the necessary oS.
Among the many offered, we find the necessary drivers for a video card and install. After installing the drivers, restart the computer.
This method determines and adjusts the computer when the computer does not see the Nvidia graphics card or when the video card is turned off.
The computer does not see a discrete graphics card
This problem is often encountered by those who reinstalled operating systems when an error occurred during installation. The solution is possible if you reboot the OS, or boot from Livecd.
Another solution is possible if you remove all drivers with the mention of Nvidia, disable the folder named Nvidia. Clean the registry. Disable the Internet, antivirus, restart and install the driver again. BUT if the proposed manipulation does not help, you need to contact the service center. They will solve problems with repair and adjustment.
The video card is responsible for the process of converting graphics to display on the monitor. Stripes on the screen, self-reset, black screen and other signs, indicate a malfunction or lack of the necessary components.
As a rule, there can be several reasons:
- incorrect bIOS settings;
- there are no drivers;
- the video card was improperly installed or it failed.
2. BIOS check
If the computer does not see the video card, then you need to make sure the monitor is working, and only then check the BIOS settings. To do this, when you start the PC, press F2 and find the video adapter section and set the necessary parameters that correspond to the video card model (find out this information from the instructions or official manufacturer's website). Save the settings by pressing F10, and reboot the system.
3. Installing drivers
Another way to fix an error, in which the distortion periodically disappears or the system does not always load, is to update the drivers. Sometimes, they do not match the video chip, or are outdated, and require reinstallation. Therefore, go to the control panel and in the video card section, update the driver. Also, you can download the necessary components yourself. Go to the official site of the manufacturer (Nvidia, AMD, Intel, etc.) and in the corresponding section "Drivers", enter the model and version of the operating system.
4. Checking the graphics card for damage and cleaning the system
If your PC does not boot and only the black screen is displayed, then check the correct installation of the video card, as well as possible damage. After turning off the PC, disconnect the system unit from the mains and wires, then, take a screwdriver and unscrew the side wall. After you have removed the part of the case, you must clean the device of dust and debris. Very often, the contamination of the cooling system leads to overheating of the video card, which can lead to the failure of the motherboard, therefore, it is necessary to clean the PC on time, and also, the replacement of thermal paste.
Remove dust with:
- special brushes;
- compressor, compressed air or vacuum cleaner.
When working, be careful, check that all screws and parts are securely fastened. Also, do not touch the cards with your hands, so as not to damage them. Then, unscrew the fixing screw of the video card and find the connection on the motherboard. After disconnecting it, remove the fastening latches and carefully remove the video card. Inspect it for defects. If visible on the surface of swelling, chips or oxidation of the contacts, the part must be replaced.
5. Replacing the video card
When choosing a new component, it is necessary to take into account all characteristics: model, system data, volume, size, power and type of connection. Install the graphics card in the connector, connect to the motherboard, tighten the screw, then, assemble the case. After shutting down the computer, install new drivers (usually they are included) and test the work.
If for some reason you could not find out why the computer does not see the video card, or are afraid of damaging the motherboard when replacing it, we recommend that you turn to a professional for help.
