After turning on the computer, the screen is not displayed, and the speaker continues to make a bee

This is a problem that computer gamers often encounter.

In the POST of the computer, if there is a failure, sometimes the bell will ring continuously, and different rings represent different error messages, according to the meaning of these information, it is not difficult to make corresponding diagnoses. The following is an example of the two more common BIOS chips (amibios and awardbios) to introduce the specific meaning of the common POST ringer**:

awardbios

1 Short: The system starts normally. Shows that there is nothing wrong with the machine.

2 Short: General error, please go to CMOSThe setup and reset the incorrect options.

1 long and 1 short: There is an error in the memory or motherboard. Try to change the memory, if it still doesn't work, you have to change the motherboard.

1 long and 2 short: The display or graphics card is wrong.

1 long and 3 short: The keyboard controller is wrong. Check the motherboard.

1 Long 9 Short: Motherboard FlashRAM or EPROM error, BIOS corruption. Try a different block of flashram.

Constant ringing (long sound): The memory module is not plugged in tightly or is damaged. Reinsert the memory module, or replace the memory.

amibios

1 Short: The memory refresh failed. Replace the memory module.

2 Short: The memory ECC verification error is incorrect. Setting the memory option for ECC check to disabled in CMOSSETUP will solve the problem, but the most fundamental solution is to replace a memory.

3 Short: The basic memory check of the system fails. Change memory.

4 Short: The system clock is wrong.

5 Short: There is an error in the CPU.

6 Short: Keyboard controller error.

7 short: The real mode of the system is wrong and cannot be switched to protection mode.

8 Short: A memory error is displayed. If there is a problem with the display memory, try changing the graphics card.

9 Short: BIOS chip check and error.

1 long and 3 short: memory error. If the memory is damaged, it can be replaced.

1 long and 8 short: A test error is displayed. The monitor cable is not plugged in properly or the graphics card is not plugged in properly.

Tell us about the specific voices?

The BIOS self-test bell of the award and its significance.

1 Short: The system starts normally. This is something we hear every day and it also shows that there is nothing wrong with the machine.

2 Short: General error, please go to CMOSThe setup and reset the incorrect options.

1 Long 1 Short: There is an error with the RAM or motherboard. Try to change the memory, if it still doesn't work, you have to change the motherboard.

1 long and 2 short: The display or graphics card is wrong.

1 long and 3 short: The keyboard controller is wrong. Check the motherboard.

1 Long 9 Short: Motherboard FlashRAM or EPROM error, BIOS corruption. Try a different block of flashram.

Constant ringing (long sound): The memory module is not plugged in tightly or is damaged. If it still doesn't work, you can only replace a memory module.

Ringing: The power supply and monitor are not properly connected to the graphics card. Check all the plugs.

Repeated short rings: Power supply issues.

No sound, no display: Power issue.

It may be that the data cable is not connected. I used to have this situation, it was caused by my hard drive not being connected, you can find out if your cable is connected.

Explain that there is no problem with your sound card, try not to do it well with the cable and plug!

There is an alarm sound when the computer is turned on, there must be a problem with the computer hardware, and it is best to use the replacement method to eliminate the problem, and the judgment method:

1. Press the upper and lower case on the keyboard. The light is on, indicating that the graphics card, monitor, and other hardware are faulty.

2. If the keyboard light does not light up, it means that it is a memory, CPU, motherboard, or power supply problem.

Solution: 1. If the keyboard light does not light up, first wipe the memory module with an eraser, and check whether the gold finger of the memory module has any burnt marks. Replace the memory in the slot.

2. Check the capacitors and resistors on the motherboard to see if the capacitors are bulging, whether there is a burning smell on the motherboard, and clean up the dust on the motherboard.

3. Remove the CPU fan, power on and turn on, test whether the CPU has a temperature change by hand, if not, the CPU is not working, either the motherboard is broken, or the CPU is not plugged in properly, and the CPU is re-plugged.

4. Power supply problem, although the power supply is powered on, but the motherboard can not work normally, replace the power supply and try it.

5. If the display card is loose, or oxidation is impulsed, the keyboard light will be on, the screen will not be displayed, wipe the gold finger of the graphics card with an eraser, and check whether the capacitance on the graphics card is bulging.

6. Minimize the test method, only leave the power supply, motherboard, CPU, memory, graphics card, keyboard, monitor, unplug the wires on all the motherboards of the rest of the liquid, and use a screwing knife to short the switch pins.
