incorrect results that may not be readily apparent. An example of a non-critical
error would be a memory chip failure.
In general, if the POST detects a system board failure (a critical error), the computer
halts and generates a series of beeps. If failure is detected in an area other than the
system board (such as the display, keyboard, or an adapter card) an error message is
displayed on the screen and testing is stopped. It is important to remember that the
POST does not test all areas of the computer, only those that allow it to be
operational enough to run diagnostic programs.
If your system does not successfully complete the POST, but displays a blank screen,
emits a series of beeps, or displays an error code, consult your dealer.
