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 computer fails the POST, the computer will either

CD'. (AMI BIOS) A power-on self-test (POST) is a process performed by firmware or software routines immediately after msi beep codes 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, http://www.computerhope.com/beep.htm or medical equipment also have self-test routines which are automatically invoked at power-on. The 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, https://en.wikipedia.org/wiki/Power-on_self-test an indicator lamp or a speaker may be provided to show error codes as a sequence of flashes or beeps. In 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.

numbers may be flashed across the screen. This alert is able to give the user an idea of any system problems that may be present and how to go about solving them. The beeps are different and http://www.liutilities.com/articles/bios-error-codes-beep-signals/ each one is specific to a particular error code. This distress signal uses a Morse code http://www.pcstats.com/articleview.cfm?articleID=1223 kind of pattern to execute its tasks but unless the PC has a diagnostic card to give details of the problem, users might have to decipher the problem by use of computer error chats. Below is a run down of the BIOS beep codes. One short beep is an indicator that the system is okay but make sure that the screen has images if not check beep codes on the monitor. Two short beeps are not a good sign since they signify memory irregularities. At this point if there is no error message on the screen, then it means that there is an error in the initial 64k memory. The SIMM’s should be checked and reset. If the computer is rebooted and if the problem persists, then the trouble could be with the PC’s memory chips. Five short beeps indicate that there is a problem with the motherboard. The memory should motherboard beep codes be reseated and the machine rebooted. Incase this does not work, then a different motherboard may be required. Six short beeps means that the motherboard chip which controls the keyboard is not working. A different keyboard should be tried and if this does not work then the chip for control of the keyboard should be reseated. If there is no improvement then the chip needs to be replaced. Seven short beeps means that the CPU could be broken and the solution to this is either replacement of the whole CPU or purchase of another motherboard. Eight short beeps shows that the video card is not in a working condition. It needs to be reseated in its position and if the beep is still present, then the entire card could be corrupted or it has problems. If the beep continues then the card needs to be replaced. Nine beeps means that the BIOS has irregularities Ten beeps indicates a problem in the CMOS Eleven beeps means that the cache memory is experiencing trouble. Ensure that the right diagnosis is made before acting on any BIO error code. Whenever IBM computers are turned on, their hardware normally runs a POST (Power-On Self Test) and if errors are encountered, they are displayed through an audio beep or a code number that flushes through the screen. With a guide on BIOS error codes, it is possible to determine the part of the system with problems and resolve the problem. Drive
Review Beginners Guides: Computer Error Beep Codes Price Check: $/£/€ Abstract: When the computer makes those funny sound via the system speaker, it's not doing it because it wants to be heard. Table of Contents Filed under: Beginners Guides Published: Author: External Mfg. Website: None Sep 17 2002 Colin Sun Home > Reviews > Beginners Guides > None Beginners Guides: Computer Error Beep Codes Since I'm the "computer expert" among my friends and family, I often get those late night phone calls and e-mails asking me what's wrong with their computer. I'll be honest. It does get quite frustrating and annoying at times when people start off with "What did I do?" I understand that they're only asking me because they trust I can do a good job, and they really don't have anyone else to turn to. When I start fixing a computer, 99% of the problems I see are software related. Most of the time it is you, the user that wrecks, breaks, crashes, or kills your computer. Sorry, I have to be blunt about it, but it's true. New processors, hard drives, video cards, memory and motherboards are just inanimate objects we can lay blame to. Most of the time the main problem with these broken computers I tend to are due to too many programs loading up at start up. All those little programs add up, and sometimes eat up all the system resources. Every now and then though, I do see a hardware problem and the first thing I do when I turn the computer on is listen to how it beeps. When the computer makes those funny sound via the system speaker, it's not doing it because it wants to be heard. The computer is trying to talk to the operator/technician and tell them what's wrong. In testing computer components on and off for the last three to four years, I find that almost all motherboards adhere to the IBM BIOS standard beep codes... I think a few OEM's have developed their own or use Phoenix or AMI beep codes, but for the most part motherboard manufacturers uses the
