Hi

EG:

LED blinks 5 times

Main-Board

General Main-Board failure.

Test the Main-Board with the minimum hardware and reseat all the connections.

If the error persists, replace the Main-Board.

LED blinks 6 times

BIOS

BIOS authentication failure.

Restore BIOS if available.

Press the Windows

 

+ B keys to do a BIOS recovery or replace the Main-Board.
