After updating the driver of the video card with the driver wizard, an exclamation mark will appear on the video card, indicating that Windows cannot verify the digital signature of the driver required by the device. This is because you updated the graphics card driver, but the previous driver file was not deleted (uninstalled), which caused the new graphics card driver to fail to load normally.

Solution: Start the operation, enter devmgmt.msc in the device manager, uninstall the graphics card driver, then restart the computer and update the graphics card driver.
