chip on the motherboard (CMOS). It controls systems devices and test memory. It allows you to configure specific parameters about the hardware in your computer such as time, date, disk drive parameters and other device settings. Beeps http://www.bndsys.com/SupportDocs/ErrorMessages/BiosBeepCodes.htm are emitted from a computer during the boot process when some problem is encountered and can http://www.techrepublic.com/article/step-by-step-deciphering-bios-beep-codes/ be used to troubleshoot a dead computer. They indicate problems such as bad memory, bad keyboard or bad motherboard. Usually if you hear beeps there is something real wrong and you should immediately turn off the computer and perform some troubleshooting. POST Beeping Error General Codes Bad Motherboard - 1 long and 1 short beep Disk drive related problem / Video card problem - 1 beep codes short beep then nothing happens Bad video card - 1 long and 2 short beeps Bad power supply - 1) continuous beeps, 2) non-stop short beeps Bad memory - 3 short beeps These codes DO vary from one manufacturer to another. Almost all computers list the appropriate codes in the User's manual under technical information or the troubleshooting section, so be sure to check the manual and verify what the codes mean. If no beeps are heard and no display is bios beep codes on the screen, it's most likely the power supply. Check for Keyboard lights or for hard drive/floppy drive lights. If lights come on then power supply is good. Next, inspect the motherboard for loose components. A loose or missing CPU, BIOS chip, Crystal Oscillator, or Chipset chip will cause the motherboard not to function. If there are lights, then it could be one of the I/O cards. Try removing each card one at a time and restarting the computer.

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 the power supply. Since POST codes are more numerous than beep codes (there may be 10 beep codes to 256 POST codes), a diagnos
