displays on the screen, the computer might use sounds (i.e., beep codes) to tell you what is wrong. Many of these asus beep codes errors indicate hardware problems that a service technician should fix. However, some errors are easily fixed. For example, keyboard controller errors often mean that your keyboard isn't plugged in. Following are beep codes for

some common brands of BIOS for PCs. For information about Mac beep codes or startup tones, see Apple Support's About Mac computer startup tones. Note: Many BIOSes will have different beep codes even if they appear to be from the same manufacturer. This is because motherboard manufacturers reprogram codes to reflect their own customizations. You can often go to the website for the motherboard's manufacturer to find the updated codes, computer beep codes but you may find cases where the manufacturer simply does not document the changes. For more about beeps and error codes, see ComputerHope.com's Computer POST and beep codes. On this page: AwardAMI (American Megatrends)AST BIOSCompaqPhoenixIBM DesktopIBM ThinkPadMylexQuadtel BIOS Award Award BIOSes typically use more screen errors than beep codes. For Award BIOSes manufactured by Phoenix Technologies, note the following from the Phoenix Technologies AwardBIOS Error Messages page: "The only AwardBIOS beep code indicates that a video error has occurred and the BIOS cannot initialize the video screen to display any additional information. This beep code consists of a single long beep followed by two short beeps. Any other beeps are probably RAM (Random Access Memory) problems." Award BIOSes not manufactured under Phoenix Technologies use the following beeps; this information is from the BIOS Central Award BIOS Beep Codes page: Beeps Meaning 1 long, 2 short Video adapter error: Bad or improperly seated video card Repeating beeps Memory error: Bad or improperly seated RAM 1 long, 3 short Bad video RAM or video card not present High-frequency beeps Overheated CPU: Check fans Repeating high/low beeps CPU: Improperly seated or defective CPU Back to top AMI (American Megatrends) The information below is from the BIOS Central AMI B

CD'. (AMI BIOS) A power-on self-test (POST) is a process performed by firmware or software routines immediately after system timer failure 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, https://kb.iu.edu/d/afzy 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, an https://en.wikipedia.org/wiki/Power-on_self-test 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.

Everything is ok, that is if you see things on the screen. If you don't see anything, check your monitor and video card first. Is everything connected? If they seem fine, your motherboard has some bad chips on it. First reset the SIMM's and reboot. If it does the same thing, one of the memory chips on the motherboard are bad, and you most likely need to get another motherboard since these chips are soldered on. 2 Short Beeps Your computer has memory problems.

An error message gives you a specific place to work from, unlike a vague symptom like a blank screen or no power at all.Important: If your computer is having trouble starting but isn't showing any kind of error message then skip these instructions and instead see How To Fix a Computer That Won't Turn On for a better troubleshooting guide for whatever symptom your computer is experiencing.Difficulty: AverageTime Required: Anywhere from a few minutes to several hours depending on the exact error messageHow To Fix Errors Seen During the Computer Startup ProcessDocument the error message exactly. While this might seem obvious to some, transcribing the error message in its entirety and without mistake is possibly the most important thing you can do when you encounter an error message while your computer is starting.Misspelling a DLL file or writing down the wrong characters in a STOP code could have you trying to fix a problem with a file, driver, or piece of hardware that you don't actually have a problem with. continue reading below our video Ways You're Probably Screwing Up Your Computer As I mentioned above, there are thousands of errors one might see during a computer's startup process.
