POST
When
you
turn
on
the
computer,
it
performs
a
series
of
tests
to
check
the
operation
of
system
components
and
some
of
the
options
that
are
installed
in
the
computer.
This
series
of
tests
is
called
the
power-on
self-test,
or
POST.
If
POST
finishes
without
detecting
any
problems,
the
first
window
of
the
operating
system
or
application
program
appears.
Notes:
1.
If
you
have
a
user
password
set,
you
must
type
the
password
and
press
Enter,
when
prompted,
before
POST
will
continue.
2.
A
single
problem
might
cause
several
error
messages.
When
this
occurs,
correct
the
cause
of
the
first
error
message.
After
you
correct
the
cause
of
the
first
error
message,
the
other
error
messages
usually
will
not
occur
the
next
time
you
run
the
test.
The
possible
types
of
beep
codes
that
the
system
might
emit
are:
Repeating
long
beeps
Indicates
that
a
memory
error
has
occurred.
Ensure
that
all
RIMMs
are
correctly
installed.
One
long
beep
and
two
short
beeps
Indicates
that
a
video
error
has
occurred
and
the
BIOS
code
cannot
initialize
the
video
screen
to
display
any
additional
information.
Ensure
that
the
video
adapter
is
correctly
installed.
Diagnostics
The
Diagnostics
program
uses
a
full
range
of
diagnostic
utilities
to
determine
the
operating
condition
of
the
computer’s
hardware
components.
For
a
complete
list
of
error
codes
and
messages,
