We are using the X7SBA motherboard with a Terratec Aureon 5.1 PCI Card. When the system shuts down, the system stops with the message “It´s now safe to turn off your computer.” The system does not shut down as if ACPI is disabled. Do you have any idea what could be wrong?
This problem has also been reported by other customers. The problem is caused by the Terratec Aureon 5.1 PCI card. Changing to different sound card will resolve this issue.
