5-3 Troubleshooting 5-3-1 Frequently Asked Questions To read more FAQs for your motherboard, please go to the Support & Downloads\FAQ page on GIGABYTE's website. Q: In the BIOS Setup program, why are some BIOS options missing? A: Some advanced options are hidden in the BIOS Setup program. Press to enter BIOS Setup during the POST. In the Main Menu, press + to show the advanced options. Q: Why is the light of my keyboard/optical mouse still on after the computer shuts down? A: Some motherboards provide a small amount of standby power after the computer shuts down and that's why the light is still on. Q: How do I clear the CMOS values? A: For motherboards that have a CMOS_SW button, press this button to clear the CMOS values (before doing this, please turn off the computer and unplug the power cord). For motherboards that have a clearing CMOS jumper, refer to the instructions on the CLR_CMOS jumper in Chapter 1 to short the jumper to clear the CMOS values. If your board doesn't have this jumper, refer to the instructions on the motherboard battery in Chapter 1. You can temporarily remove the battery from the battery holder to stop supplying power to the CMOS, which will clear the CMOS values after about one minute. Q: Why do I still get a weak sound even though I have turned my speaker to the maximum volume? A: Make sure your speaker is equipped with an internal amplifier. If not, try a speaker with power/amplifier. Q: Why cannot I install the onboard HD audio driver successfully? (For Windows XP only) A: Step 1: First, make sure Service Pack 1 or Service Pack 2 has been installed (check in My Computer > Properties > General > System). If not, please update it from Microsoft's website. Then make sure the Microsoft UAA Bus Driver for High Definition Audio has been installed successfully (check in My Computer > Properties > Hardware > Device Manager > System Devices). Step 2: Check if Audio Device on High Definition Audio Bus or Unknown device is present in Device Manager or Sound, video, and game controllers. If yes, please disable this device.

Step 3: Then go back to My Computer > Properties > Hardware > Device Manager > System devices and right-click on Microsoft UAA Bus Driver for High Definition Audio and select Disable and Uninstall. Step 4: In Device Manager, right-click on the computer name and select Scan for hardware changes. When the Add New Hardware Wizard appears, click Cancel. Then install the onboard HD audio driver from the motherboard driver disk or download the audio driver from GIGABYTE's website to install.
