This is because the video card and sound card driver are not installed. If you have other boards or peripherals in your system, you have to reinstall the driver.

Note: during the installation process, you must install the system files in the same directory as the original system. After such installation, most of the general problems can be solved. More importantly, some previously installed applications can still be used.
