Troubleshooting :
Fail to update BIOS


Solution Fail to update BIOS

If you fail to update BIOS which results in no POST :

1. Please clear CMOS and test again ( refer to motherboard manual for details .)

  • Use CMOS Jumper :
    a.) Turn OFF the computer and unplug the power cord
    b.) Move the jumper cap from pins 1-2 ( default .) to pins 2-3. Keep the cap on pins 2-3 for about 5-10 seconds, then move the cap back to pins 1-2.

    c.) Plug in the power cord and turn ON the computer.
    d.) Hold down the "Del" key during the boot process and enter BIOS setup to re-enter data.

  • Use the CMOS switch on the back I/O of the motherboard.
    a.) Press down the “clr CMOS” switch on the back I/O.
    b.) Hold down the "Del" key during the boot process and enter BIOS setup to re-enter data.
    ( It is the CLRTC_SW jumper .)


    Note :
    1. The “clr CMOS” switch will not function if the CLRTC_SW jumper is moved to the disable position.
    2. Ensure to re-enter your previous BIOS settings after you clear the CMOS.
    3. You do not need to clear the RTC when the system hangs due to CPU overclocking. With the C.P.R.( CPU Parameter Recall .) feature, shut down and reboot the system so the BIOS can automatically reset CPU parameter settings to default values..)


2. If the PC still cannot POST after updating the BIOS, there may be something wrong with the BIOS chip/ CMOS. Please consider contacting your retailer to have a further check if the motherboard is still under its 3 years warranty.



If you fail to update BIOS and result in the error message as the following screenshot :


  • Please use the CrashFree utility to recover the BIOS step by step.
    First, please check what revision of CrashFree BIOS utility your motherboard supports:
    If using CrashFree BIOS utility, you can recover the BIOS from a floppy disk.
    If using CrashFree BIOS 2 utility, you can recover the BIOS from the support CD or from a floppy disk.
    If using CrashFree BIOS 3 utility, you can recover the BIOS from the support CD or from a USB flash disk.

  • To recover the BIOS from the support CD :
    a.) Turn on the system.
    b.) Insert the motherboard support CD into the optical drive.
    c.) The utility displays the following message and automatically checks the CD for the BIOS file.

    When found, the utility reads the BIOS file and starts flashing the corrupted BIOS file.

    ( Note : DO NOT shut down or reset the system while updating the BIOS! Doing so can cause system boot failure! )
    d.) Restart the system after the utility completes the updating process.

  • To recover the BIOS from a floppy disk :
    a.) Remove any CD from the optical drive, and then turn on the system.
    b.) Insert the floppy disk with the original or updated BIOS file to the floppy disk drive.
    c.) The utility displays the following message and automatically checks the floppy disk for the original or update BIOS file.

    Jika CD tidak ditemukan, utilitas secara otomatis mengecek floppy drive perihal file BIOS. Kemudian, utilitas akan menjalankan proses perbaikan file BIOS yang rusak/corrupt.
    ( Note : DO NOT shut down or reset the system while updating the BIOS! Doing so can cause system boot failure! )
    d.) Restart the system after the utility completes the updating process.
    ( Note : The recovered BIOS may not be the latest BIOS version for this motherboard. Visit the ASUS website www.asus.com to download the latest BIOS file. )

  • To recover the BIOS from a USB flash disk.
    a.) Insert a USB flash disk that contains the BIOS file to the USB port.
    b.) Turn on the system.
    c.) The utility will automatically checks the devices for the BIOS file. When found, the utility reads the BIOS file and starts to flash the corrupted BIOS file.
    d.) Restart the system after the utility completes the updating process.
    ( Note : DO NOT shut down or reset the system while updating the BIOS! Doing so can cause system boot failure! )
    ( Note : The recovered BIOS may not be the latest BIOS version for this motherboard. Visit the ASUS website www.asus.com to download the latest BIOS file. )


2. If the BIOS could not be recovered successfully, please clear the CMOS ( refer to the manual introduction .)


3. If the problem still persists, please contact your retailer to have a further check.
