The computer POST (Power On Self Test)
tests the computer, insuring that it meets the necessary system requirements and that all hardware is working properly before starting the remainder of the boot process. If the computer passes the POST the computer will have a single beep (with some computer BIOS manufacturers it may beep twice
) as the computer starts and the computer will continue to start normally. However, if the computer fails the POST, the computer will either not beep at all or will generate a beep code, which tells the user the source of the problem.
This issue can be caused by any of the below situations.
- New hardware conflicting with old hardware.
- Bad or failing hardware device.
- Connections not connected or connected properly.
- Recent electrical storm that caused a surge that damaged computer.
- Other hardware issue.
you can determine the meaning of your beeps finding out with your BIOS System installed on your machine.
Usually you probably have some memory problem.
