Power-on self-test
Whenever the computer is turned on, the power-on self-test (POST)
routine test various hardware components, including memory, and
compares the actual configuration of the computer with that
recorded in configuration (CMOS) memory. During this time, BIOS
sign-on and POST messages are displayed.
A configuration discrepancy could arise if you have just installed or
removed a hardware option (for example, if you have added or
replaced a SIMM). In this case you may be prompted to invoke the
BIOS Setup utility.
If POST detects a hardware fault, one or more POST error codes
and messages are displayed (see table opposite). You may also be
prompted to "Press the F1 key to continue" or "Press any key when
ready". The computer may be able to continue despite the error
indication (for example, if a memory chip fails POST, the computer
can continue with less memory).
If the problem persists, call your supplier or authorized maintainer.

Your first action should be to turn off the computer, wait at
least 30 seconds, and then turn it on again to see if the error is
transient or persistent. Persistent POST errors may indicate a
fault in the system.
Check that all external cables are securely connected.
Try running the BIOS Setup utility to reconfigure the system.
Open up the system unit and check that all internal signal and
power cables are securely connected.
