Beeps Computer

• 1 short beep
     Normal - system is ready to operate under appropriate circumstances.
 
• 2 short beeps
     Error - an error code is displayed on the screen;
 
    -Could not start the computer;
 

    -This problem is caused by a serious failure in any component, that the BIOS was not able to identify the problem is usually on the motherboard or the memory modules.
  
• Continuous beep, repeated short beeps.
 
    -Power supply,
    -System Problem,
    -Keyboard.
 
• Do not beep.
 
    -Power supply,
    -System problems,
    CPU-unplugged
    -Sound disconnected.
 
  
• 1 long beep and two short beeps or one long beep and 3 short beeps.
 
     -Video adapter with the problem.
     -Problems with the video card BIOS.
    -Resolution: Try removing the card, pass a vinyl eraser on contacts and place it in another slot. Most often this problem is caused by poor contact.
 
  
• 1 long beep: Refresh failed (refresh Failure):
 
    -The refresh circuit of the motherboard is faulty.
    -Can be caused by damage to the motherboard or faults in the RAM modules.
 
  
• 2 long beeps: Parity Error:
 
    -During POST has detected a parity error in RAM.

 

• 3 long beeps:
 
    -It was detected a serious problem in the first 64K of RAM (Base 64k memory failure)
    -Cause:
        'Defect in memories or in the motherboard
        "Bad touch
 
    -Resolution: Try removing the memory banks and clean the contacts using a rubber vinyl and replacing them with care.
 
  
• 4 Long Beeps:
 
     Non-operating-Timer: The Timer 1 is not operational or can not find the RAM.
    -This might be the motherboard (most likely) or in memory modules
 
 

• 5 beeps:
 
     Error-processor.
    Processor damaged,
    Ill-fitted,
    Check if the processor is seated properly (check the socket lever Zif)
 
  
• 6 beeps:
 
     -Failed at Gate 20.
    The 20-gate is a signal generated by the chip 8042, responsible for putting the processor into protected mode.
 
    -The problem can be
        'Processor damaged
        'Problems with the 8042 chip located on the motherboard.
 
 

• 7 beeps:
 
    -Processor Exception (interrupt error): the processor generates an interrupt.
    -Processor has been erratic
    -Cause: An unsuccessful overclock
    -Resolution: lowering the operating frequency of the processor.
        "If it does not you should replace the processor
  
• 8 Beeps:
 
    -Error memory video card (display memory error).
    -Cause: bad contact.
        'Remove the video card, pass the rubber contacts and carefully replace the slot.
        "If not resolved - probably the video card is damaged.
 

 

• 9 Beeps:
 
    Error-in ROM (ROM checksum error).
    -Problems with flash memory, which has recorded the BIOS.
    -Cause: A physical damage in the BIOS chip, caused:
        'By a BIOS upgrade unsuccessful
        'By the action of a virus of the family of Chernobyl.
 
  
• 10 beeps:
 
    -Failure in CMOS shutdown register (CMOS shutdown register error):
    -Cause: a defect in CMOS
        "Does a physical change of the chip to the motherboard.
 
 

• 11 beeps:
 
    -Problems with the cache (cache memory bad).
    - Usually the BIOS can boot the system normally, disabling the cache.
    However, this is not very desirable deteriorates system performance.
    -Resolution: Login to the Setup and increase the waiting times of cache memory. Sometimes it comes back up normally.
