电脑开机各种滴声引起的电脑故障解析大全（Computer fault analysis Daquan computer boot drops caused by various） 电脑开机各种滴声引起的电脑故障解析大全(Computer fault analysis Daquan computer boot drops caused by various) When the computer is switched on, it is normal to have a sound "drop" sound. If we find the sound is wrong, we can judge the difference of the computer's hardware area in most cases. For example, the boot computer has been dripping, dripping sound, the failure may be memory contact bad or damage, etc., the following computer network will be a detailed description of the computer may appear in the sound and the emergence of faults. Computer boot sound, that is BIOS self-test when the fault detected by the sound prompt. BIOS self check ring meaning First, Award BIOS self-test bell meaning: 1 short: the system starts normally. Congratulations, your machine doesn't have any problem. 2 short: general error, please go to CMOS Setup and reinstall incorrect options. 1 long 1 short: RAM or motherboard error. Try another memory. If it doesn't work, you'll have to replace the motherboard. 1 long 2 short: monitor or display card error. 1 long 3 short: keyboard controller error. Check main board. 1 long 9 short: motherboard Flash, RAM or EPROM error, BIOS damage. Try another Flash RAM. Keep ringing (Chang Sheng): memory bars are not plugged or damaged. Re insert memory, or if not, only the replacement of memory. Keep ringing: the power, the monitor is not connected to the display card. Check all the plugs. Repeat short sound: power problems. No sound, no display: power problems. Two, AMI BIOS self-test bell meaning: 1 short: memory refresh failed. Change memory bar. 2 short: memory ECC than error. In CMOS Setup, the memory option for ECC validation is set to Disabled, but the most fundamental solution is to replace one 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, cannot switch to protection mode. 8 short: display memory error. Show memory problems, try replacing video cards. 9 short: ROM, BIOS test and error. 1 long 3 short: memory error. Memory corruption, replace it. 1 long 8 short: display test error. The monitor 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 check ring 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 error 1 short, 4 short, 2 short, basic memory checksum error 1 short, 4 short, 4 short, EISA NMI error 3 short, 1 short, 1 short, error from DMA register 3 short, 1 short, 3 short primary interrupt processing register errors 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 numeric coprocessor errors 1 short, 1 short, 1 short system power initialization failed 1 short, 1 short, 3 short, CMOS, or battery failure 1 short, 2 short, 1 short system clock errors 1 short, 2 short, 3 short, DMA page register errors 1 short, 3 short, 2 short, basic memory error 1 short, 4 short, 1 short basic memory address line errors 1 short, 4 short, 3 short, EISA timing device errors 2 short, 1 short, 1 short, pre 64K basic memory error 3 short, 1 short, 2 short main DMA register errors 3 short, 1 short, 4 short, error from interrupt handling register 3 short, 3 short, 4 short screen memory tests 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 to: Long sound constantly sound: memory is not inserted. 2 short: the system starts normally. 2 short: CMOS settings error, need to reset. 1 long 1 short: memory or motherboard error. 1 long 2 short: monitor or video card error. 1 long 3 short: keyboard controller error. 1 long 9 short: motherboard BIOS FLASH RAM or EPROM error. 2) the BIOS of AMI is set to: 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 long 8 short: display data lines or graphics cards are not inserted. 3) Phoenix BIOS 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 sequencer error 1 short, 4 short, 4 short: EISA NMI 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: numeric coprocessor error 4) compatible with BIOS alarm tone code 1 short: the system is normal 2 short: system power on self check (POST) failed 1 long: power error, if not shown, is a 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 long 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 Generally, there is a problem with the power supply that is common to 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 drive performance is poor, often crashes. When these conditions occur, it is better to check that the output of each voltage is low and that these problems occur irregularly when +5V and +12V are below 10%. Because the power supply has voltage output, it often wastes a lot of time by mistake 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 situation in the INTEL and Gigabyte some kind of motherboard, if the system appears "didi"..." The continuous chirp is not a power failure, but a memory failure alarm, which requires attention. 2., "toot, toot," ambulance sound, accompanied by the long sound of the boot 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 DEG C as soon as it is turned 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 PIV's CPU temperature sensor is integrated inside the CPU, when the system shows the CPU temperature is more accurate. General host as long as one boot, the system prompted CPU temperature is about 50 degrees Celsius, which is normal. 3. "didi"... Didi..." A long continuous sound with intervals. 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, the general graphics card loose, graphics card damage, or the motherboard's graphics power supply failure. 5. beep twice long after no movement, will hear "read floppy creak" sound. If an image indicates that the system will start from the 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. in the WIN system, press the "Caps Lock" and "Num Lock" and "Scroll Lock" these three keys, the host's PC horn has "didi" similar tone. 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. However, because some people do not understand where the false edge, it is considered a motherboard problem. 7. a short beep Normally, this is the sound that the system checks through and the system starts up normally. However, some boards do not have this cue sound when they are checked through themselves, and nothing sounds. Also note that some of the motherboard self-test time may be longer, will wait five or six seconds before you hear "didi" a sound, you need a little patience. I believe you are familiar with the above knowledge, you can simply deal with some of the computer failure, so that the accumulation of knowledge slowly, and soon you can become a computer master Oh.
