computer error 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.

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
