384655	2005-08-30 12:50:00	Hi I got a ONE LONG BEEP bios codes noise from my computer from time to time when the computer is running. ( no problem to start up the computer) I have the computer checked out by computer shop (I have also run the memory test for 7 hours, not error appear)but the 1 long beep noise still there. Can anyone help to sort out this one beep problem? Gigabye 81915P Duo Pro motherboard. P4 3.2ghz CPU 1g DDR2 Ram Gigabye NX66T128VP PCI-E graphic card 120g h/d Thank you.	chinadoll (682)
384656	2005-08-30 13:08:00	I saved a txt file to my comper concerning Beep codes. I'll copy and paste it below. It's mainly for older computers but It maybe of help to you?....... What is a BIOS Beep Code? When you power on a computer the BIOS immediately takes control of the computer and performs the P.O.S.T (Power On Self Test). At the end of the POST the computer will play an audible 'BEEP' through either the PC's internal speaker of through speakers attached to the sound card (if you have a built-in sound chip). If the POST completed successfully without detecting any problems with then system will play a single short beep to let you know the test is complete and the computer will continue to startup and load the operating system. If during the POST the BIOS detects a problem it will normally display a visual error message on the monitor explaining what the problem is. However, if a problem is detected before the BIOS initializes the video card, or a video card is not present or not detected then the BIOS will play several 'BEEPS' through the speaker to let you know there is a problem. Depending on the type of the BIOS you have the BIOS may play beeps in a specific pattern to indicate what the problem is, or play the same beep a number of times indicating the problem. It is very important that you pay close attention to the number and/or pattern of the beeps your computer plays on startup. Below is a table of the most common AMI, Phoenix and Award BIOS beep codes. AMI (American Megatrends International) BIOS Beep Codes. AMI BIOS uses beeps of the same length and pitch. The error is displayed as a number of beeps. For example, 4 beeps indicated a timer failure. BEEP CODE MEANING POSSIBLE CAUSE 1 Beep (No video) Memory refresh failure Bad memory 2 Beeps Memory parity error Bad memory 3 Beeps Base 64K mem failure Bad memory 4 Beeps Timer not operational Bad motherboard 5 Beeps Processor error Bad processor 6 Beeps 8042 Gate A20 failure Bad CPU or Motherboard 7 Beeps Processor exception Bad processor 8 Beeps Video memory error Bad video card or memory 9 Beeps ROM checksum error Bad BIOS 10 Beeps CMOS checksum error Bad motherboard 11 Beeps Cache memory bad Bad CPU or motherboard Award BIOS Beep Codes Award BIOS uses beeps of varying duration. A long beep will typically last for 2 seconds while a short beep will last only 1 second. Award BIOS also uses beeps of different frequency to indicate critical errors. If an Award BIOS detects that the CPU is overheating it may play a high pitched repeating beep while the computer is running. BEEP CODE MEANING POSSIBLE CAUSE 1 Long, 2 Short Video adapter failure Bad video adapter Repeating (Endless loop) Memory error Bad memory or bad connection 1 Long, 3 Short Video adapter failure Bad video adapter or memory High freq. beeps (while running) CPU is overheating CPU fan failure Repeating High, Low beeps CPU failure Bad processor Phoenix BIOS Beep Codes Phoenix BIOS uses beep code patterns to indicate problems. In the table below the '-' indicates a brief pause between beeps. Example: 1 - 1 - 2 would sound like BEEP <pause> BEEP <pause> BEEP BEEP BEEP CODE MEANING POSSIBLE CAUSE 1 - 1 - 2 CPU / motherboard failure Bad CPU / motherboard 1 - 1 - 3 CMOS read/write failure Bad motherboard 1 - 1 - 4 BIOS ROM failure Bad BIOS chip 1 - 2 - 1 Timer failure Bad motherboard 1 - 2 - 2 DMA failure Bad motherboard 1 - 2 - 3 DMA failure Bad motherboard 1 - 3 - 1 Memory refresh failure Bad memory 1 - 3 - 2 64K memory failure Bad memory 1 - 3 - 3 64K memory failure Bad memory 1 - 3 - 4 64K memory failure Bad memory 1 - 4 - 1 Address line failure Bad memory 1 - 4 - 2 Parity error Bad memory 1 - 4 - 3 Timer failure Bad motherboard 1 - 4 - 4 NMI port failure Bad motherboard 2 - 1 - 1 64K memory failure Bad memory 2 - 1 - 2 64K memory failure Bad memory 2 - 1 - 3 64K memory failure Bad memory 2 - 1 - 4 64K memory failure Bad memory 2 - 2 - 1 64K memory failure Bad memory 2 - 2 - 2 64K memory failure Bad memory 2 - 2 - 3 64K memory failure Bad memory 2 - 2 - 4 64K memory failure Bad memory 2 - 3 - 1 64K memory failure Bad memory 2 - 3 - 2 64K memory failure Bad memory 2 - 3 - 3 64K memory failure Bad memory 2 - 3 - 4 64K memory failure Bad memory 2 - 4 - 1 64K memory failure Bad memory 2 - 4 - 2 64K memory failure Bad memory 2 - 4 - 4 64K memory failure Bad memory 2 - 4 - 4 64K memory failure Bad memory 3 - 1 - 1 Slave DMA failure Bad motherboard 3 - 1 - 2 Master DMA failure Bad motherboard 3 - 1 - 3 Interrupt controller failure Bad motherboard 3 - 1 -4 Slave IC failure Bad motherboard 3 - 2 -2 Interrupt Controller failure Bad motherboard 3 - 2 - 3 <RESERVED> 3 - 2 - 4 Keyboard control failure Bad motherboard 3 - 3 - 1 CMOS batter failure Bad CMOS battery 3 - 3 - 2 CMOS configuration error Incorrect setting 3 - 3 - 3 <RESERVED> 3 - 3 - 4 Video memory failure Bad video card or memory 3 - 4 - 1 Video init failure Bad video card or memory 4 - 2 - 1 Timer failure Bad motherboard 4 - 2 - 2 CMOS shutdown failure Bad motherboard 4 - 2 - 3 Gate A20 failure Bad motherboard 4 - 2 - 4 Unexpected interrupt Bad processor 4 - 3 - 1 RAM test failure Bad memory 4 - 3 - 3 Timer failure Bad motherboard 4 - 3 - 4 RTC failure Bad motherboard 4 - 4 - 1 Serial port failure Bad motherboard 4 - 4 - 2 Parallel port failure Bad motherboard 4 - 4 - 3 Coprocessor failure Bad motherboard or CPU. 9 - 2 - 1 Video adapter incompatibility Use a different brand of video card	lazydog (148)
384657	2005-08-30 20:14:00	One long beep is (usually) a memory error. Could be anything from a bad contact with the mobo, to memory on its way out. Try reseating the RAM in the motherboard, see if that helps	Myth (110)
384658	2005-08-30 21:46:00	Hi Tazz I only received one long high pitch beep, some time is one short beep no error appear on monitor. My bios is Award Thank you	chinadoll (682)
384659	2005-08-30 22:08:00	Chinadoll, do you have a microphone attached by any chance? (feedback) Just thinking, it may not be a POST code because the computer is up and running. Also, does the beep come from the internal speaker or external speakers? :2cents:	B.M. (505)
384660	2005-08-31 01:26:00	Looks like a fairly new PC If you bought from a shop and it's still under warranty take it back and tell them to sort it. Be careful they just dont disconnect the system speaker though I reckon it's pretty unlikely to be a bios beep if you're already into windows though. If the memory was bad, XP would more than likely not start or crash as soon as the desktop tried to load I'd be looking elsewhere for the problem Does your case have a "Case open notification" option in the bios or through a 3rd party monitoring program, if it does disable it and see if you get the beeping again	bartsdadhomer (80)
384661	2005-08-31 05:08:00	Hi guys It is very new home build computer. No mic attach to computer, only a internal buzzer. I have this problem checked out by the computer shop who I brought the graphic card from. Now, while Im typing this notice I don't get any beep noise. ( from turn on computer to finish this notice, sometimes it does sometimes it doesn't) Any ideas? Thank you.	chinadoll (682)
384662	2005-08-31 05:20:00	If you get a long beep while Windows is running, it's not a BIOS POST error indicator. Once the POST has finished, and the OS is booting, the POST code is forgotten until the next start up. Have a look at the Control panel "Sounds" page, and see if a long beep shows that something meaningful to Windows has happened.	Graham L (2)
384663	2005-08-31 05:52:00	I haven’t experienced the problem "1st hand", but I think on a machine such as yours you can get a “temperature warning beep”. You say it’s home built, so are all the fans running and the heat-sinks properly fitted?	B.M. (505)
384664	2005-08-31 07:12:00	Check to make sure you don't have any stuck keys on the keyboard. I've had my system beeping at me before due to the keyboard buffer overflow alert.	Jen (38)
