The computer won t turn on, and the host power supply has a high frequency of tweeting

The power supply of the computer is aging and cannot be turned on because the voltage is insufficient. If the sound is too loud, you can clean the power supply fan or replace it with a new one. The fundamental solution to the problem is to spend dozens of dollars to change the power supply of the host.

AMI's BIOS self-test bell and its significance.

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

2 Short: Memory ECC verification error. 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 system basic memory (the first 64kb) check failed. Change memory.

4 Short: The system clock is wrong.

5 Short: Processor (CPU) error.

6 Short: Keyboard controller error.

7 Short: The system is in real mode and cannot be switched to protection mode.

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

1 Long 3 Short: Memory error. If the memory is damaged, it can be replaced.

1 Long 8 Short: Displays test errors. The monitor cable is not plugged in properly or the graphics card is not plugged in properly.

High Frequency Constant Ringing: CPU Overheating Alarm.

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 CMOS setup and reset the incorrect option.

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 2 Short: Wrong monitor or graphics card.

1 Long 3 Short: Keyboard controller error. 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 damaged. Reinsert the memory module, if it still doesn't work, you have to replace it.

One piece of memory. 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.
