How to know problem to error beep codes

Description of beep code

Beep code Means

⑴AMI BIOS beep codes (fatal error) 

1 Beep

 DRAM Refreshing Fails. Try to reseat the memory first. If the error still occurs, replace the memory with known good chips. 

2 Beeps

arity Error in First 64K RAM. Try to reseat the memory first. If the error still occurs, replace the memory with known good chips.

3 Beeps 

as 64K RAM Failure. Try to reseat the memory first. If the error still occurs, replace the memory with known good chips.

4 Beeps

5 Beeps beeps rocess fails

6 beeps 

Keyboard Controller 8042 - Gate A20 is Error. Try to reseat the keyboard controller chip. If the error still occurs, replace the keyboard chip. If the error persists, check parts of the system relating to the keyboard, e.g. try another keyboard, check to see if the system has a keyboard fuse

7 beeps

Processor Virtual Mode Exception Interrupt Error 

8 beeps
