电脑开机各种滴声引起的电脑故障解析大全（Computer fault analysis of all kinds of drop sound caused by computer） 电脑开机各种滴声引起的电脑故障解析大全(Computer fault analysis of all kinds of drop sound caused by computer) When the computer is switched on, the sound is normal. If we find the sound is wrong, in most cases we can judge the problem of the hardware in the computer by the difference of the sound. For example, the boot computer has been dripping, dripping sound, the failure may be memory contact bad or damage, etc., the following computer Pepsi network will give you a detailed description of the computer may appear sound and the emergence of failure. The sound that appears when the computer starts up, that is the sound prompt when the BIOS checks the fault. The meaning of BIOS self-test bell First, the meaning of Award BIOS self-test bell: 1 short: the system starts normally. Congratulations, your machine doesn't have any problems. 2 short: conventional errors, please go to CMOS Setup, reinstall the wrong options. 1 long 1 short: RAM or motherboard error. Try another memory. If it doesn't work, you have to replace the motherboard. 1 length 2 short: monitor or display card error. 1 length 3 short: keyboard controller error. Check motherboard. 1 long 9 short: motherboard Flash RAM or EPROM error, BIOS damage. Try changing block Flash RAM. Constantly ringing (Chang Sheng): memory bars are not plugged or damaged. Re insert memory, if not, only replace a memory. Keep ringing: the power, the monitor and the display card are not connected. Check all the plugs. Repeat short: power problem. No voice, no display: power problems. Two, AMI BIOS self-test bell meaning: 1 short: memory refresh failed. Change memory bar. 2 short: memory ECC more error. In CMOS Setup, the memory of the ECC checksum option is set to Disabled can be resolved, but the most fundamental solution is to replace a memory. 3 short: system basic memory (first 64kB) failed to check. Swap memory. 4 short: system clock error. 5 short: central processing unit (CPU) error. 6 short: keyboard controller error. 7 short: system real mode error, can not switch to protection mode. 8 short: display memory error. Display memory problems, try to change the video card. 9 short: ROM BIOS test and error. 1 long 3 short: memory error. Memory is damaged, replace it. 1 long 8 short: display test error. The display data line is not plugged in or the display card is not plugged in. Three, Phoenix BIOS self-test bell meaning: Self test ring, self test bell meaning 1 short system start normal 1 short, 1 short, 2 short motherboard errors 1 short, 1 short, 4 short ROM BIOS checksum errors 1 short, 2 short, 2 short DMA initialization failed 1 short, 3 short, 1 short RAM refresh errors 1 short, 3 short, 3 short basic memory errors 1 short 4 short 2 short basic memory check error 1 short, 4 short, 4 short EISA NMI mouth errors 3 short, 1 short, 1 short from DMA register error 3 short, 1 short, 3 short main interrupt processing register error 3 short, 2 short, 4 short keyboard controller error 3 short, 4 short, 2 short display errors 4 short 2 short 2 short shutdown error 4 short 2 short 4 short protection mode interrupt error 4 short, 3 short, 3 short clocks, 2 errors 4 short, 4 short, 1 short serial port errors 4 short, 4 short, 3 short digital coprocessor errors 1 short, 1 short, 1 short system power initialization failure 1 short, 1 short, 3 short CMOS or battery failure 1 short 2 short 1 short system clock error 1 short, 2 short, 3 short DMA register errors 1 short, 3 short, 2 short basic memory errors 1 short 4 short 1 short basic memory address line error 1 short, 4 short, 3 short EISA timing device errors 2 short 1 short 1 short 64K basic memory error 3 short, 1 short, 2 short main DMA register errors 3 short 1 short 4 short from interrupt processing register error 3 short, 3 short, 4 short screen memory test failed 3 short, 4 short, 3 short clock errors 4 short, 2 short, 3 short A20 door errors 4 short, 3 short, 1 short memory errors 4 short, 3 short, 4 short clock errors 4 short, 4 short, 2 short parallel port errors Motherboard alarm sound detail 1) the BIOS of AWARD is set as: The long sound keeps ringing: the memory is not tight enough. 2 short: the system starts normally. 2 short: CMOS setting error, need to reset. 1 long 1 short: memory or motherboard error. 1 long 2 short: display or graphics card error. 1 length 3 short: keyboard controller error. 1 long 9 short: motherboard BIOS FLASH RAM or EPROM error. 2) the BIOS of AMI is set as: 1 short: memory refresh fault. 2 short: memory ECC checksum error. 3 short: system basic memory check failed. 4 short: system clock error. 5 short: CPU error. 6 short: keyboard controller error. 7 short: system real mode error. 8 short: display memory error. 9 short: BIOS chip inspection error. 1 long 3 short: memory error. 1 length 8 short: display data line or graphics card is not inserted. 3) BIOS Phoenix self-test bell and its significance 1 short system start normal 1 short 1 short 1 short: system power initialization failed 1 short 1 short 2 short: motherboard error 1 short 1 short 3 short: CMOS or battery failure 1 short 1 short 4 short: ROM BIOS checksum error 1 short 2 short 1 short: system clock error 1 short, 2 short, 2 short: DMA initialization failed 1 short, 2 short, 3 short: DMA page register error 1 short 3 short 1 short: RAM refresh error 1 short 3 short 2 short: basic memory error 1 short, 4 short, 1 short: basic memory address line error 1 short 4 short 2 short: basic memory check error 1 short, 4 short, 3 short: EISA timing device error 1 short 4 short 4 short: EISA NMI mouth error 2 short 1 short 1 short: previous 64K basic memory error 3 short, 1 short, 1 short: DMA register error 3 short 1 short 2 short: main DMA register error 3 short 1 short 3 short: Main interrupt processing register error 3 short, 1 short, 4 short: error from interrupt handling register 3 short, 2 short, 4 short: keyboard controller error 3 short 1 short 3 short: Main interrupt processing register error 3 short 4 short 2 short: display error 3 short 4 short 3 short: clock error 4 short 2 short 2 short: shutdown error 4 short 2 short 3 short: A20 door error 4 short 2 short 4 short: protection mode interrupt error 4 short 3 short 1 short: memory error 4 short, 3 short, 3 short: clock 2 error 4 short 3 short 4 short: clock error 4 short, 4 short, 1 short: serial port error 4 short 4 short 2 short: parallel port error 4 short, 4 short, 3 short: Digital coprocessor error 4) compatible with BIOS alarm tone code 1 short: the system is normal 2 short: system power self-test (POST) failed 1 long: power error, if not displayed, is the display card error 1 long 1 short: motherboard error 1 long 2 short: video card error 1 short 1 short 1 short: power error 3 length 1 short: Keyboard error When the maintenance of the computer, we often encounter the boot, BIOS error sound, if the reason we are familiar with these sounds, that we exclude computer fault is very convenient, can solve the problem in the shortest possible time. 1, "didi"..." Continuous tone In general, there is a problem with the power supply that is common in the host computer. However, sometimes the power output voltage is low, the host does not alarm, but there will be hard disk loss, CD-ROM disk performance is poor, often crash situation. When these conditions occur, it is best to check the output of each voltage, whether it is low, and when +5V and +12V are less than 10%, the problem will occur irregularly. Because the power supply has a voltage output, it often wastes the time of the motherboard or the hard disk. The cause of low output voltage is part of the output filter capacitor loss or leakage caused by the reduced DC component, high frequency AC component in power supply increase, would interfere with the normal operation of the main board, which makes the system unstable, prone to crashes or blue screen phenomenon. However, this is on a INTEL and Gigabyte motherboard, if the system appears "didi"..." Continuous short song, not the power failure, but memory failure alarm, this need attention. 2., "blare, blare, sound" ambulance sound, along with the starting sound long non-stop This is the CPU system overheat alarm sound, mostly because in the main internal dust, clean the CPU radiator or because of the replacement of the CPU fan is new, because the installation is not in place, CPU radiator and CPU contact is not strong, there is a certain space or in with debris, causing CPU heat from the normal shed, CPU is up to 80-90 centigrade as soon as it is switched on. If the PIII is below the CPU, because the temperature test is adopted in CPU temperature probe near CPU to collect the temperature values of temperature and CPU of the actual numerical display there are some errors about 10-20 degrees of difference. And the PIV CPU temperature sensor is integrated in the CPU, when the system displays the CPU temperature is more accurate. The general host as long as the boot, the system prompted CPU temperature is about 50 degrees Celsius, which is normal. 3. "didi"... Didi..." A continuous interval of long tones. This is the memory alarm sound, generally loose memory, memory gold finger and memory socket bad contact, memory gold finger oxidation, memory of a chip failure and other reasons. 4. "didi"... Tweet, continuous didi the unexpected accidents This is the graphics card alarm, generally graphics card loose, graphics card damage, or motherboard graphics power supply failure. 5. beep twice long after no movement, will hear "read floppy creak" sound. If an image shows that the system will start from floppy disk, the floppy disk is being read. If there is no floppy disk in the floppy drive, the system will indicate that no system cannot start and the system hangs up. 6. under the WIN system, according to "Caps Lock" and "Num Lock" and "Scroll Lock" these three keys, the host's PC horn has "didi" similar tone keys. For example, the emperor PV40ML, this is a reminder of the motherboard, prompts the user to change the input state of the keyboard is not a fault. But because some people do not understand the false edge, it is considered that the motherboard is a problem. 7. a short note of "beep" In general, this is the voice of the system through the normal boot of the system. However, when some boards pass the test, there is no such hint, and there is no sound. Also note, some motherboard self-test time may be longer, will wait for five or six seconds to hear "didi" a voice, need to be a little patience. I believe that you are familiar with the above knowledge, you can simply deal with some of the computer failure, so that the accumulation of knowledge slowly, you will soon become a computer master Oh.
