  Some users reported that after the video capture card was installed on the computer, the system automatically installed the driver, but the software could not be run. What should I do if this happens?
  There may be several reasons why the video capture card driver cannot run normally after installation:
  1. Driver incompatibility or error: The installed driver may be incompatible with your operating system version, or the driver file may be damaged during the download or installation process.
  2. Installation error: An error may occur during the driver installation process and it is not installed correctly in the system. Check if there are devices with yellow exclamation marks or question marks in the device manager, which usually indicates that there is a problem with the device driver.
  3. Hardware conflict: There is a resource conflict between the capture card and other hardware devices, such as resources such as interrupt request lines (IRQs) or I/O addresses being occupied by other devices.
  4. BIOS setting problem: Some video capture cards may require specific settings in the BIOS, such as turning on or off certain functions, to be correctly identified and used.
  5. Physical connection problem: The video signal cable is not connected properly, or the capture card is not properly installed in the PCI/PCI-E slot of the motherboard.
  6. System configuration issues: Certain operating system settings may cause the capture card to not work properly, such as power management settings that limit hardware performance.
  7. Resolution or display mode mismatch: The resolution supported by the video capture card does not match the display or software settings, resulting in the inability to display the picture.
  8. Outdated system updates: System updates may sometimes introduce new compatibility issues that affect the normal operation of the driver.
  Solutions usually include:
  • Reinstall the driver: Uninstall the original driver first, then download the latest driver that is compatible with your system from the official website and reinstall it.
  • Check the hardware connection: Make sure that the capture card and all related cables are connected correctly.
  • Update BIOS: If you suspect that it is a BIOS setting problem, you can try to update the motherboard BIOS to the latest version. • Check system settings: Adjust the relevant settings in the operating system to ensure that there is no configuration that limits hardware performance. • Troubleshoot hardware conflicts: Check and resolve possible hardware resource conflicts in the device manager.
  • Reset or update the system: As a last resort, you can consider refreshing or reinstalling the operating system, but this should be the last choice to solve the problem.
  If the above steps cannot solve the problem, it is recommended to contact the manufacturer of the capture card for technical support, or seek professional IT help.
