Case 3 — Boot Process Fails and Monitor is Blank

Before removing the cover, always switch off the display and PC Workstation.
Disconnect the power cord and any accessory cables. When checks have been
completed, close the PC Workstation and reconnect the power cord and accessory
cables. Verify that the PC Workstation boots correctly.
When your PC starts up, its BIOS performs a Power-on Self Test
(POST) to test your hardware configuration for any problems. If a
problem is detected during the POST, an error is displayed on your
PC's monitor.
If, however, your PC is unable to display an error message (for
example, when you graphics controller has failed), it will emit a
buzzing sound. Immediately after the buzzing sound, a series of beeps
is emitted.
If you hear a series of beeps, you should count them as this will help
you detect the cause of the problem.
