4-2 Troubleshooting
Below is a collection of general asked questions. To check general asked questions based on a specific
motherboard model, please log on to www.gigabyte.com.tw
Question 1: I cannot see some options that were included in previous BIOS after updating BIOS. Why?
Answer: Some advanced options are hidden in new BIOS version. Please press Ctrl and F1 keys after
entering BIOS menu and you will be able to see these options.
Questions 2: Why is the light of my keyboard/optical mouse still on after computer shuts down?
Answer: In some boards, a small amount of electricity is kept on standby after computer shuts down
and that's why the light is still on.
Question 3: How do I clear CMOS?
Answer: If your board has a Clear CMOS jumper, please refer to the Clear CMOS steps in the manual.
If your board doesn't have such jumper, you can take off the on-board battery to leak voltage to clear
CMOS. Please refer to the steps below:
Steps:
1. Turn off power.
2. Disconnect the power cord from MB.
3. Take out the battery gently and put it aside for about 10 minutes (Or you can use a metal object
to connect the positive and negative pins in the battery holder to makethem short for one
minute).
4. Re-insert the battery to the battery holder.
5. Connect power cord to MB again and turn on power.
6. Press Del to enter BIOS and load Fail-Safe Defaults(or load Optimized Defaults).
7. Save changes and reboot the system.
Question 4: Why do I still get a weak sound after turning up the speaker to the maximum volume?
Answer: Please make sure the speaker you are using is equipped with an internal amplifier. If not,
please change another speaker with power/amplifier and try again later.

these beeps usually stand for?
