It is normal for the computer to make one or two short beeps during the startup process or during a BIOS update. Let the process continue and do not interrupt it. However, if the computer beeps and Windows does not start properly, a more serious hardware problem exists. The most common problems that cause beeping sounds are: Memory and heat-related failures caused by a build-up of dust in critical cooling areas A keyboard key is stuck A memory DIMM or hard drive cable is not seated properly A component on the motherboard has failed A basic computer function was unable to start What to do when beep codes occur Listen to the beeping sound and write down the number of beeps before each pause, if the beeps are long or short, or if the beeps high or low in tone. Once a pattern is determined, use the following beep code table to identify which component might be causing the proble

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 di
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 are emitted from a computer during the boot process when some problem is encountered and can 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 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 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.
