Part 1. Understanding The Cause Behind Video Cards Not Detected
Before resolving the issue, you need to understand why your system displays a graphics card not found error. In many cases, simple troubleshooting steps resolve the problem, while in others, deeper system adjustments are needed. Below are the most common reasons your video card might not be detected:
Causes | Description |
Defective Slot | If the card slot on the device is damaged, the system may fail to detect it. Thus, you should test the card in a different slot or on another motherboard to identify the real problem. |
Improper Placement | When the graphics card isn't seated correctly in its primary slot, the system may fail to detect it. That's where you should reseat the card and clean the slot to restore its functionality. |
Power Connection | Most dedicated video cards require external power from the PSU. So, you need to verify that the correct power connectors are plugged in securely and your power supply meets the requirements. |
Damaged GPU | Sometimes, physical damage to the graphics card can prevent its detection on your device. In such a case, you have to test the GPU on another system to confirm whether it’s working or not. |
Old Video Card | In case your graphic drivers are old or missing, your system might not recognize the card. Here, you should reinstall or update drivers through your device’s manager to resolve the issue. |
Part 2.Potential Solutions Behind "Graphics Card Not Found"
Upon understanding the possible reasons, it's time to apply practical solutions. As we discussed, no video card detected error can disrupt gaming, editing, or general system use if this issue is not addressed timely. So, let’s dive below to explore the 5 proven solutions to help you resolve this problem.
Way 1. Check the Card Slot
The most common reason for a VGA card not detected error is an improperly seated video card. When it isn’t securely installed in the designated slot, the system may fail to recognize it. Here, you need to turn off your device and open its case. Afterward, carefully remove the graphics card and clean the video card slot to remove dust.
Going ahead, just reinsert the card firmly by ensuring it clicks into place, and the locking mechanism is engaged. Plus, if your motherboard has multiple card slots, you should try inserting the card into a different one. After reseating the card, simply power on the system and check if it is recognized.
Way 2. Reinstall Essential Drivers (Device Manager + Reinstallation)
When checking the card slot didn't resolve the issue; you should try to reinstall your graphic driver. Sometimes, a computer not detecting video cards often results from missing or incompatible drivers, which prevents proper GPU communication with the system. Thus, follow the detailed steps below to learn how to fix your video card not detected problem by using this method:
Step 1. You need to navigate to “Device Manager” on your desktop and locate your inserted video card driver. Afterward, click the right mouse button on the driver under the “Display Adaptors” section and choose the “Uninstall Device” option.

Step 2. Upon seeing a small dialog box, press the “Uninstall” button to successfully delete it. After a few seconds, you need to restart your device, and your deleted driver will be automatically reinstalled on your PC.

Way 3. Manage BIOS Settings
Another problem that might cause this issue is incorrect BIOS settings on your device. A VGA not detected error can occur when the system prioritizes integrated graphics instead of the dedicated GPU. So, go through the instructions below to explore how you can manage these settings and resolve this problem:
Instruction. To fix this, restart your PC and enter the “BIOS” by pressing the designated key (usually F2 or F12). Upon accessing it, look for display settings and set the primary graphics adapter to PCIe instead of integrated graphics. Afterward, save changes, restart your system, and check if the GPU is recognized.

Way 4. Update Device Drivers
If the above methods don’t resolve the issue, you have to update your drivers to fix the laptop not detecting the graphics card problem. In case your video card is not detected, it means that your system is running an old driver version. Without wasting any time, follow the steps below to update your video card driver:
Step 1. To commence the task, open “Device Manager” and locate your GPU under the “Display Adapters” section. After that, right-click on the driver that is not detected and select the “Update Driver” option.

Step 2. Going ahead, choose “Search Automatically for Drivers” and let the system update it. After updating, you need to restart your system and check if the GPU is detected.

Way 5. Check If Video Card is Faulty
A video card not recognized error can also occur if the card is defective. In such cases, you need to test it on another computer to check your video card status. In case the card isn’t detected there either, it’s likely damaged. Along with that, you can also try a different GPU in your system to confirm whether the issue is with the card or your device.
