If the test identifies a hardware problem, the BIOS will display an error message on the monitor. But, if the failure occurred before the BIOS could access the video card, the BIOS will issue special beep codes to alert the user to the problem.In this article, I'll take a detailed look at the beeps that are issued by various BIOS manufacturers, and I'll provide you with a resource for more detailed information. Understanding these noises will allow you to troubleshoot a multitude of hardware problems.Annoying noises, flashing lightsDuring a POST session, your computer has several ways to communicate: Either through flashing indicator lights, the computer's speaker, or via the monitor. Since the monitor is not initialized until later in the process, early failures are communicated by red or absent status lights, such as the power and hard drive activity lights, or by sound in the form of beeps.POST diagnostic cards Another option is to purchase a POST diagnostic card to intercept POST errors at their source via the ISA or PCI bus. Cards are available for either bus and typically contain one or two digital readouts that present the codes, as well as LEDs for monitoring th
