Why does the computer host call, and the desktop computer host beeps?

If the temperature is too high, it will automatically shut down the protection.

Prompt for boot self-test, under normal circumstances, everyone hears a "drop" sound when they turn on the computer, and the computer starts successfully, but if the host hardware fails, such as no beep, the computer does not respond, or there are multiple honey sounds of different lengths, then this is the host failure.

phoenix bios1 Short: The system starts up normally.

1 short, 1 short, 1 short: The system 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 verification error.

1 Short, 2 Short, 1 Short: The system clock is incorrect.

3 Short 2 Short 4 Short: Keyboard controller error.

3 Short 3 Short 4 Short: A memory error is displayed.

3 Short 4 Short 2 Short: Error is displayed.

4 Short, 2 Short, 1 Short: Clock error.

4 Short 2 Short 2 Short: Shutdown error.

4 Short, 3 Short, 1 Short: Memory error.

4 short, 4 short, 1 short: The serial port is wrong.

4 short, 4 short, 2 short: the parallel port is wrong.

ami bios1 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 CMOS Setup 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.

award bios1 Short: The system starts normally. Shows that there is nothing wrong with the machine.

2 Short: General error, please go to CMOS 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 Flash RAM or EPROM error, BIOS corruption. Try a different block of flash ram.

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

1. Excessive dust accumulation in the CPU fan: Regularly clean the dust on the fan blades and heat sink with a small brush.

Chunhuai chain 2, the CPU temperature is too high: reduce the standby time of the computer and shut down the computer in time after use.

3. Aging of the computer host: It can be solved by replacing the aging parts inside the computer.

4. Hard disk overload: Close multiple large applications running at the same time and release computer memory to solve the problem.

5. Blockage of the main engine vent: Move the computer host away and keep the distance between it and the wall to solve it.

6. The voltage is not enough to stabilize the computer: click the "Power" button to turn off the computer, and restart the computer after increasing the voltage.

There are several reasons and solutions:

1. Didi continuous short tone, in general, it is common to have problems with the power supply of the host. In addition, sometimes when the output voltage of the power supply is low, the host does not alarm, but the hard disk is lost, the reading performance of the optical drive is poor, and it often crashes;

2. The sound of the rescue and destruction of the ambulance, accompanied by the long sound of the boot, this situation is the alarm sound of the CPU overheating system, mostly because of the dust removal inside the host, cleaning the CPU radiator or because the new CPU fan is replaced, because the installation is not in place, the CPU radiator and the CPU are not in good contact, there is a certain space or there are debris added in between, resulting in the heat emitted by the CPU can not be dissipated in a positive bend;

3. The continuous interval long sound of Di Di is the sound of memory burning alarm and alarm, which is generally due to loose memory, poor contact between the gold finger of the memory and the memory slot, oxidation of the gold finger of the memory, and failure of a chip in the memory.

Causes: 1. Poor contact of simple mining memory modules. Remove the memory module, use a hair dryer to clean the memory module slot, and then use an eraser to wipe all the gold fingers of the memory module, and then install the memory module correctly, and fasten the clips at both ends of the memory module to change the phenomenon of poor memory contact.

2. CPU fan. Open the host to the core of the barricade, sweep the electric blind source fan and the CPU fan to the floating soil, check whether there is a lack of oil, and add a few drops of lubricating oil to the rotating shaft.

Memory ECC verification error. X0D X0A3 Short Beeps: The self-test of the basic memory (the first 64KB capacity) of the system fails.

CPU error. x0d x0a6 beep: Keyboard controller error.

Displays memory errors (such as showing memory corruption). X0D X0A9 Beeps: Motherboard FlashROM or EPROM verification error (e.g. BIOS corrupted by CIH virus).

x0d x0a1 long 3 short beeps: memory error (e.g. memory chip corruption). x0d x0a1 long 8 short beeps:

x0d x0a2 short beep: General error. You should go to CMOSTathe and reset the incorrect options.

Wrong monitor or display card. x0d x0a1 long beep 3 short beeps: The keyboard controller is wrong.

The memory is not plugged in properly or the chip is damaged. X0D X0A keeps ringing: The monitor is not connected to the graphics card.

You can refer to the above explanation, and then repair the mistakes according to the mistakes.
