Computer boot alarm

Today, a friend asked me why I had an alarm when my computer turned on. I believe many people have encountered such problems.

There are many kinds of boot alarm sounds.

1 long 9 short: The Flash Ram or EPROM on the motherboard is incorrect, and the BIOS is damaged.
Constant sound (long sound): the memory stick is not plugged in or damaged.
The power supply and display are not connected to the video card.
Duplicate short response: power supply problems.
No sound, no display: power supply problems.

Awi bios:
1 short: failed to refresh the memory. Solution: Replace the memory stick.
2 short: Memory ECC verification error. Solution: Go to the CMOS settings and disable ECC verification.
3 short: the system basic memory (1st 64kb) Check failed.
4 short: system clock error.
5 short: CPU error.
6. Short: the keyboard controller is incorrect.
7. Short: The system real-time mode is incorrect and cannot be switched to the protection mode.
8: memory error is displayed. Note: the memory of the video card is short for video memory.

1 long 3 short: memory error.
1 long, 8 short: The test error is displayed.
