POST

• Every computer has a diagnostic program built
  into its BIOS called the power-on self-test
  (POST). When you turn on the computer, it
  executes this set of diagnostics. Many steps are
  involved the POST, but they happen very quickly,
  theyre invisible to the user, and they vary
  among BIOS versions. The steps include checking
  the CPU, checking the RAM, checking for the
  presence of a video card, and so on. The main
  reason to be aware of the POSTs existence is
  that if it encounters a problem, the boot process
  stops. Being able to determine at what point the
  problem occurred can help you troubleshoot.
