When you start your computer, the screen remains blank and beeps twice. Which of these would be the most likely cause of this issue?
A) The boot device is not connected
B) The memory is faulty
C) The operating system has become corrupted
D) The PC is infected with malware
E) Beep-beep, beep-beep, yeah!
The answer: B) The memory is faulty
The POST (Power On Self-Test) is the initial diagnostics that checks for a good hardware foundation. If any of the tests fail, a message will appear on the screen. If the failure is to a system that prevents the screen from displaying a message, the BIOS will provide a number of beeps instead. If you check your system documentation, you can determine what the error is based on the number of beeps during startup.
