Troubleshoot PC According to Asus Beep Codes

About Asus Beep Codes

I’m having a hardware failure when booting and I need to know the exact beep-code definitions for the Asus M5A97 LE R2.0. Could someone provide me the beep-codes of that motherboard? I can’t find them in the ASUS webpage and other beep-codes that I’ve found are not exact for this UEFI. — superuser.com

Like other PCs, Asus PCs also use buzzers to troubleshoot monitor display issues. But most people may don’t know what Asus beep codes mean. To know what Asus beep codes, you can do as follows:

Step 1: Check the motherboard model. You can check that in BIOS or on the sticker label attached on the bottom panel of your PC.

Step 2: Search this model online to find Asus support site for this model. Open this web page and find the user manual of this model. Open this manual to see whether Asus has mentioned beep codes.

Asus will not explain the beep codes in all motherboard models. For example, it has explained the Asus beep codes in the manual of M5A97 LE R2.0, but it doesn’t explain that in the manual of Asus Z97-A/USB3.1.

If you have tried all of the above methods but the issue persists still, Asus suggest you try clearing CMOS, which may help to recover the motherboard, as this will restore the BIOS defaults. To clear CMOS, you can use the following 2 ways.

Way 1: Use CLRTC Pin

• Turn off the computer and unplug the power cord.
• Make two CLRTC jumper caps short-circuit with a metal conductor. Keep the conductor connected to the jumper caps for about 5-10 seconds. The location of the CLRTC is generally in the lower right corner of the host version.
• Plug-in the power cord and turn ON the computer.
• Hold down the <Del> key during the boot process and enter BIOS setup to re-enter data.

Ways 2: Use Battery

• Turn off the computer and unplug the power cord.
  Open the computer case.
  Locate the battery on the motherboard.
  Unplug the battery on the main board, then short-circuit the positive/negative terminal of the battery holder for about 1 minute, and then re-install the battery.
  Reconnect the power and turn on, enter the BIOS, reset the time and date, and Load Optimized Defaults.
