starting the remainder of the boot process. If the computer passes the POST, the computer may give a single beep (some computers may beep twice) as it starts and continue to boot. However, if the asus beep codes computer fails the POST, the computer will either not beep or generate a beep gigabyte beep codes code that tells the user the source of the problem. If your computer has an irregular POST or a beep code not hp bios beep codes mentioned below, follow the POST troubleshooting steps to determine the failing hardware component.

I get 2 beeps at POST which supposedly means parity circuit failure. I tried playing with the RAM (make sure it seated properly, tried different slots, tried different memory sticks) but that wasn't the problem. I thought it might be the motherboard so I replaced the MOBO and also purchased http://forums.devshed.com/motherboards-106/boot-2-beeps-post-187734.html new RAM. Last night the problem returned.....the house power flickered for a second, the computer went down and then tried to re-boot itself but couldn't. It just gave the two beeps. I completely shut it down for about five minutes then came back and tried booting it and it booted fine. This has happened in the past also where the house power flickers, computer won't re-boot, turn it off for 5-10 minutes and then it starts fine. The problem has also occurred on some cold boots in the morning but that is pretty rare. It's obviously not the MOBO or RAM. What else can cause the 2 beeps? Any thoughts? Thanks.

by introducing more precise citations. (October 2010) (Learn how and when to remove this template message) The first stage of a typical POST operation. (AMI BIOS) The second stage of a POST. Sometimes, https://en.wikipedia.org/wiki/Power-on_self-test it is shown 'Boot from CD'. (AMI BIOS) A power-on self-test (POST) is http://www.bndsys.com/SupportDocs/ErrorMessages/BiosBeepCodes.htm a process performed by firmware or software routines immediately after a computer or other digital electronic device is powered on. This article mainly deals with personal computers, but many other embedded systems such as those in major appliances, avionics, communications, or medical equipment also have self-test routines which are automatically invoked at power-on. The beep codes results of tests run by the POST may be displayed on a panel that is part of the device, output to an external device, or stored for future retrieval by a diagnostic tool. Since a self-test might detect that the system's usual human-readable display is non-functional, an indicator lamp or a speaker may be provided to show error codes as a sequence of flashes or beeps. In post error code addition to running tests, the POST process may also set the initial state of the device from firmware. In the case of a computer, the POST routines are part of a device's pre-boot sequence and only once they complete successfully is the bootstrap loader code invoked to load an operating system.

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.
