Sometimes after we insert the video capture card correctly, the computer cannot recognize the video capture card. What is the reason? The main reason is that the video capture card is not installed properly, or the driver of the video capture card is incorrect, which causes the operating system to be unable to recognize it. This phenomenon is more common in the WIN7 operating system. Is there a good solution?
If your computer has a video capture card installed but cannot recognize it, you can try the following steps to solve this problem:
1. Check the physical connection:
• Make sure that the capture card is correctly and firmly installed in the corresponding slot of the motherboard (such as the PCIe slot). For external capture cards, make sure that the USB or Thunderbolt cable is stably connected to the computer.
2. Restart the computer:
• After installing new hardware, you usually need to restart the computer to let the system re-detect the hardware.
3. Clean the gold finger:
• If it is a built-in card, turn off the power, remove the capture card, gently wipe the gold finger part with an eraser to remove the oxide layer or dust, and then reinsert it.
4. Replace the slot:
• Try to replace the capture card with another slot of the same type on the motherboard. Sometimes it is a slot compatibility issue.
5. Manually install the driver:
• Visit the official website of the capture card manufacturer and download the latest driver. Usually you can find it on the "Support" or "Download" page.
• Close all unnecessary programs, run the downloaded driver installer, and follow the prompts to complete the installation.
• If the installer does not automatically recognize the device, you can manually add new hardware in the device manager, select "Install from disk", and point to the downloaded driver file path.
6. Check the device manager:
• Go to the "Device Manager" and check if there are any unknown devices with a yellow exclamation mark. This may be an incorrectly identified capture card. Right-click the device and select "Update Driver" or "Uninstall Device" and then rescan for hardware changes.
7. System compatibility settings:
• Confirm the compatibility of the operating system and the capture card. Sometimes you may need to adjust some settings in the BIOS, such as turning on or off certain advanced features.
8. Contact technical support:
• If the above steps do not solve the problem, it may be due to hardware failure or deep system problems. At this time, you should contact the technical support of the capture card manufacturer for professional help.
