What should I do if there is no sound in the headphones, stereo and boot after the Great Wall computer reinstalls the system?
Did you install the sound card driver first? Download the driver wizard without installing it and automatically detect and install it. If there is no sound after installation, please uninstall and reinstall. Remember to uninstall the sound card driver before reinstalling. If not, change a CD and reinstall the system. This is because the computer is too old and the new driver is incompatible.
