At some time or another as computer owners, we may
all experience motherboard problems, and feel that we need
a motherboard replacement. Issues such as
booting problems, and general computer instability can be
caused by a fault in your motherboard's BIOS.
The BIOS of a PC software is
built into the PC, and is the first code run by a PC
when powered on. The primary function of the BIOS is to
enable your computer to start and load the operating
system. The BIOS initializes and identifies system
devices such as the video card, Keyboard and mouse, Hard
Drive, CD/DVD drive, and other hardware.
BIOS software is stored on a ROM
chip, on the mother board and thus many hardware related
computer problems can be "troubleshot" by first....
"Clearing the CMOS." ("clearing
cmos")
Clearing the CMOS will
restore the default settings in all BIOS menus. Clearing
the CMOS won't however; restore the original BIOS
version (such as in the event of a failed BIOS update).
Signs that you may need to clear CMOS on your computer
are:
1.)You
made changes to the BIOS settings and now your computer
won't boot or is unstable.
2.)You
want to make BIOS changes but you can't remember your
system password, and the system has "locked" you
out.
3.)Your
Windows clock, date and time are incorrect and change
frequently without you making the changes.
4.)Your
BIOS settings have become "corrupted" and either won't
save your preferences, or won't allow you to return the
BIOS back to "default settings."
Follow these
instructions to troubleshoot your particular
issues:
1.) Disconnect your power by either shutting off
the power switch on the back of your power supply or by removing
the power cable entirely.
--------------
2.)Allow the power
supply and transistors in the motherboard to discharge;
several minutes to make sure. You can also
press (and hold) the power button several times on the
computer case, which will drain the stored
power.
--------------
3.)Move the CMOS
jumper to the "clear" position. This is mostly done by
moving the jumper from the original "1-2 position", to
"2-3 position" as demonstrated in the photo
below.
** If you can't
locate the jumper on your motherboard, you may need to
refer to your motherboard manual
**
---------------
4.)Return the CMOS
jumper to it's normal position (pin 1-2), after waiting
approximately 30 seconds. (see picture above)
--------------
5.)Plug your power cord back into the
computer and power
it on !
