Weak current College】 【post drop sound understanding.

<br> <br> We can often encounter boot, the BIOS error tones, if we are familiar with these sounds, we exclude computer failure is very convenient, can in the shortest possible time to solve the problem. <br> <br> .1, "di di ..." continuous short codes <br> <br> In general there is a host of power. But sometimes the output voltage is low, the host and not the police, but there will be a hard disk is .lost, the drive to read disk performance is poor, often panic situation. When that happens, it is best to check the voltage of the output, if low, when the + 5V and + 12V below 10%, it will not appear above on .a regular basis. Because the power supply with voltage output, often mistaken motherboard problems or problems with your hard disk, and waste a lot of time. Result output voltage low because the output section of the filter capacitor failure caused less leakage, DC components decreases ., the power supply of high-frequency AC ingredients, interfere with the Board's work, causing system instability, prone to crash or blue screen. <br> <br> However this situation at INTEL and gigabyte motherboard for a class, if the system has .a "di di ..." continuous short song, and is not a power failure, but a memory fault alarm, this needs attention. <br> <br> 2. a chorus of "uh La La" ambulance sound, accompanied by .a post long rang incessantly <br> <br> This is a CPU overheating of the system, alarm, mostly because in the dust, for the host internal clean CPU heat sink or replace a new CPU fan, because the installation is not in place ., the CPU heatsink and CPU access is not strong, there is a certain space or in the meantime with debris, cause CPU's heat does not powder, a power-on CPU on up to 80-90 ℃. If you are following CPU PIII, .because the CPU temperature is close to the CPU temperature probe near to acquisition, numerical display of the temperature and the actual CPU temperature numerical error of approximately 10-20 ° c difference. And PIV CPU temperature sensor is integrated in the CPU, then the system .displays the CPU temperature is more accurate. General host as long as a post, prompted by the CPU temperature is 50 ° c, this is normal. <br> <br> 3. "di ... Di ..." long continuous .with interval. <br> <br> This is memory alarm sound, usually loose memory, the memory of Goldfinger and bad memory slot, memory of Goldfinger oxidation, a memory chip failure. <br> <br> 4. "di .. .. A "beep" sounds ", two short of continuous tweets <br> <br> This is a video of the police, in General is the graphics card is damaged, loose, or part of the video card power supply motherboard failed. < .br> <br> 5. the "beep" sound after two long nothing, while later hear "gezhigezhi" reading the floppy disk drive. <br> <br> If you have image display prompts the system will boot from the floppy drive, .reading the floppy disk. If you do not have a floppy in the floppy drive, the system prompts are no system fails to boot, the system hangs. <br> <br> 6. in the WIN system by the "CapsLock" and " .NumLock "and" ScrollLock "these three keys, the host PC speaker has" di "similar key codes. <br> <br> For example, of the three emperors PV40ML this motherboard a hint feature that prompts the user to change the keyboard input .state, is not a fault. However, because some people do not understand where the margin of the puppet, we think there is a problem with the motherboard. <br> <br> 7. short "di" of a sound <br> .<br> Normally, this is the system post through, the system starts with a beep. However, some Board post by, in the absence of such a tone, no sound no. Also note that some Board post time may be longer, it .will wait for five seconds before they will hear the "di" sound, you need a little patience. <br> <br> You can alert sounds to judge the length, figure out where the problem <br> AWARDBIOS ringing of general meaning is .: <br> 1 short: system boots. This is what we could hear every day, as well as the machine without any problems. <br> 2 short: General error, please go to CMOSSetup, reset incorrect options. <br> 1 .long and 1 short: RAM or the motherboard. Try changing one memory, if it still doesn't work, had to replace the motherboard. <br> 1 long and 2 short: monitor or display card error. <br> 1 long 3 .short: keyboard controller error. Check the motherboard. <br> 1 long 9 short: motherboard FlashRAM or EPROM BIOS corruption errors. Swap block FlashRAM try. <br> Constantly ringing (long): memory not plug or damage. To plug in the .memory stick, or no, only replace a memory. <br> Non-stop ring: power supply, the monitor does not display card and connected. Check out all of the plug. <br> Repeat a short ring: power problems. < .br> No sound no show: power problems. <br> <br> <br> AMIBIOS ringing of general meaning is: <br> 1. a short tones, memory refresh failure. Memory corruption more serious, I'm afraid I have .to replace the memory is not available. <br> 2. two short tones, memory parity errors. You can enter the CMOS setting memory Parity parity options turned off, which is set to Disabled. But in General, the memory stick with parity and .open in the CMOS settings, this parity on the stability of the computer system. <br> 3. the three short tones, basic memory (1 of 64Kb) check failed. Replace the memory. <br> 4. four short tones, the .system clock. Repair or replace the motherboard. <br> 5. five short tones, CPU error. But not necessarily all of the wrong CPU itself, or CPU socket or there is a problem somewhere else, if this CPU in other motherboard correctly, .then certain errors in theTo the motherboard. <br> 6. six short tones, keyboard controller error. If the keyboard is not plugged in, it's easy to plug in the line; if the keyboard is connected properly but there is an error, you .may wish to exchange a good keyboard, try it; otherwise it is keyboard controller chip or relevant part of the problem. <br> 7. seven short tones, real mode error, you cannot switch to the protected mode. It also belongs to the .motherboard. <br> 8. eight short tones, video memory read / write errors. Video storage chip may be damaged. If the storage is detachable, as long as you identify bad patch and replace the line, otherwise the video need repair or replacement .. <br> 9. nine short tones, ROMBIOS inspection errors. Heat exchanger blocks of the same type BIOS try, if well prove that there is a problem with the BIOS, you can override even hot-swappable method attempts to recover. <br .> 10. ten short tones, register read / write errors. Can only be to repair or replace the motherboard. <br> 11. eleven short tones, cache error. <br> 12. If you don't hear a beep sound ringtones .do not see the screen display, first you should check the power supply is connected, when in the often oversights and repair, not connected to the motherboard power is power-on test. Secondly, have a look at is what little plug parts, such .as CPU, memory, etc. Once again, unplug all questionable card, only display cards a try. Finally found the motherboard clear (clear) CMOS jumper settings, clear the CMOS settings, BIOS back to factory State. If the monitor or display card .and line work, CPU and memory are also no problem, after the above steps, the computer when powered on or has no display or ring the Bell, it can only be the motherboard. <br> <br> <br> POENIX BIOS beep .sound (former boss, there are many POENIX, can now be acquired AWARD) <br> 1 short system boot normal <br> 1 short and 1 short and 1 short system power-up initialization failed <br> 1 short and 1 short 2 .short Board errors <br> 1 short and 1 short 3 short CMOS or battery failure <br> 1 short and 1 short 4 short ROMBIOS checksum error <br> 1 short short short 1 2 system clock errors <br> 1 short short short 2 .2 DMA initialization failed <br> 1 short short short 3 2 DMA page register error <br> 1 short 3 short 1 short RAM refresh error <br> 1 short 3 short 2 short basic memory error <br> 1 short 3 short 3 short .basic memory error <br> 1 short 4 short 1 short base memory address line errors <br> 1 short 4 short 2 short basic memory parity error <br> 1 short 4 short 3 short EISA series for errors <br> 1 short 4 short .4 short EISANMI mouth errors <br> 2 short 1 short and 1 short front 64K basic memory error <br> 3 short 1 short and 1 short DMA register failure <br> 3 short 1 short 2 short master DMA register failure <br> 3 .short 1 short 3 short Master interrupt register error <br> 3 short 1 short 4 short from interrupt processing register error <br> 3 short 2 short 4 short keyboard controller error <br> 3 short 1 short 3 short Master interrupt register error <br .> 3 short 4 short 2 short display error <br> 3 short 4 short 3 short clock errors <br> 4 short 2 short 2 short shutdown errors <br> 4 short 2 short 3 short gate A20 errors <br> 4 short 2 short .4 short protection mode interrupt error <br> 4 short 3 short 1 short memory error <br> 4 short 3 short 3 short clock 2 errors <br> 4 short 3 short 4 short clock errors <br> 4 short 4 short 1 short serial .port error <br> 4 short 4 short 2 short parallel port error <br> 4 short 4 short 3 short numeric coprocessor error <br> <br> <br>.
