Signals when you turn on the computer
When the computer is turned on, the BIOS tests the basic hardware to make sure that all hardware is working properly before you begin the process of further loading the operating system.
If the computer passes the test, published one short beep (for some motherboards two short beeps). If when you start the computer the BIOS does not complete the test, or the audio signals will not or will be generated by the combination of signals that tells the user the source of the problem.
Signals when you turn on the computer may indicate faulty RAM, graphics card or motherboard.
