[. . . ] When you installing AGP card, please make sure the following notice is fully understood and practiced. If your AGP card has "AGP 4X/8X(1. 5V) notch"(show below), please make sure your AGP card is AGP 4X/8X(1. 5V). AGP 4X/8X notch Caution: AGP 2X(3. 3V) card is not supported by VIA® KT400A. Please insert an AGP 4X/8X(1. 5V) card Example 1: Diamond Vipper V770 golden finger is compatible with 2X/4X mode AGP slot. It can be switched between AGP 2X(3. 3V) or 4X (1. 5V) mode by adjusting the jumper. [. . . ] If the case have been opened, "Case Opened" will show "Yes". If you want to reset "Case Opened" value, set "Reset Case Open Status" to "Enabled" and save CMOS, your computer will restart.

[. . . ] Answer: Gigabyte motherboards will auto-detect the external VGA card after it is plugged in, so you don't need to change any setting manually to disable the onboard VGA. Please refer to the user manual and check whether you have connected any cable that is not provided with the motherboard package to the USB Over Current pin in the Front USB Panel. If the cable is your own cable, please remove it from this pin and do not connect any of your own cables to it.
