Tips for a great answer:
this motherboard is supposed to have crash free BIOS an overclocking ability and power loss restart
is it happening
on boot up the drivers have not been loaded or might not be detecting a
bootable device the first things to check are the leads motherboard to your
hard drive make sure they are securely seated with no dust built up also the
same with computer ram and cmos battery and make sure the sockets are cleanThis message is generated by computers with SCSI / RAID
controllers when no bootable drive is detected on the controller. This is not
an error message unless you have a bootable drive on the SCSI / RAID or you are
wanting to use a SCSI or RAID drive. If you are not using a SCSI or RAID drive
and your computer has onboard a SCSI or RAID controller, this message can be
disabled by entering the computer CMOS Set up and disabling the onboard SCSI or
During the boot process you will see on the screen to press
delete to enter setup Press and hold delete during the boot up process to enter
BIOS you can load failsafe defaults
or load optimized defaults ,press escape then press f10 to save to cmos
to restart If your computer is unable to boot or you wish to restore
the BIOS back to bootable settings and your computer uses an ACER BIOS, press
and hold the F10 key as you turn on the computer. While continuing to hold the
F10 key, you should hear two beeps indicating that the settings have been
restored. AMI BIOS
Older AMI BIOS could be restored back to bootable settings by pressing
and holding the Insert
key as the computer is booting.
BIOS / CMOS diskettes
Early 486, 386, and 286 computers may
have required a floppy disk in order to enter the BIOS setup. These diskettes
are known as ICU, BBU, and SCU disks. Because these diskettes are unique to
your computer manufacturer, you must obtain the diskettes from them. See the computer manufacturers
list for contact information.
Early IBM computers
Some models of early IBM computers required
that the user press and hold both mouse buttons as the computer was booting in
order to enter the BIOS setup.
Finally, if none of the above suggestions help get you into your CMOS setup you can cause a stuck key error, which will usually cause the CMOS setup prompt to appear and remain until you press a key to continue. To do this press and hold any key on the keyboard and do not let go (you may get several beeps as you're doing this). Keep holding the key until the computer stops booting and you're prompted with an option to enter setup or to press another key to continue booting.
hope this helps
