Resetting the BIOS to default may correct it. From within system BIOS >> Main Menu, choose either Load Fail-Safe or Load Optimized. Save and Exit.
From the software DVD which shipped with your motherboad >> Application Software, install Face Wizard. This app allows you to reload the default BIOS screen or to load an image of your choice (new image must be .pcx or .bmp format, max size 640x480)
