Long beep coming from my CPU

Asked By 450 points N/A Posted on -

Hi Buddies,

I got a problem with my Personal desktop computer. Last night I worked on it like other days. But, this morning it was not running.

When I am pressing the power button on my CPU, a long sound coming out of the CPU box. It is really a weird sound. It sounds like ‘beep’, a long beep. I have checked the power connections properly, but the fault is not there.

Then I opened the CPU box. I have not found anything wrong there in it. CPU fan was spinning, Motherboard’s led was lighting correctly.

So, where is the fault?

Can anybody help me to make my PC as well? I think there should be a silly thing for which my PC is behaving like that. Friends, I need help to solve this matter.

My Desktop PC is totally new and I Use windows XP. The other configuration is below:

Dual core Processor,

1 GB of ram,

500 GB Sata HDD,

DVD writer,

Gigabyte duel bios motherboard,

Thank you.

Long beep coming from my CPU

The first to do is to count the number of beeps; each beeping sound has a meaning, beeping sound usually indicate a problem with you Bios, without your Bios working properly your computer won’t work since it’s responsible for loading the operating system and hardware device configurations.

Every time you power on your computer the BIOS run the POST (Power on Self Test), a normal PC produces a single beep to notify you that test is successful. The following is a list of BIOS beep sound from AMI, Phoenix and Award BIOS manufacturers.

AMI; beeps is of the same length and pitch but the number varies:

  • One Beep – Bad memory
  • Two Beeps -Bad memory
  • Three Beeps-Bad memory
  • Four Beeps -Bad motherboard (timer malfunction)
  • Five Beeps- Bad processor
  • Six Beeps – Bad CPU or Motherboard
  • Seven Beeps- Bad processor
  • Eight Beeps – Video memory error Bad video card or memory
  • Nine Beeps – Bad BIOS
  • Ten Beeps – Bad motherboard
  • Eleven Beeps – bad CPU or motherboard

Phoenix; each beeps sequence has a rhythm , e.g. 1-1-2 is beep <pause> beep <pause> <two beeps>

  • 1 – 1 – 2 CPU / motherboard failure Bad CPU / motherboard
  • 1 – 1 – 3 CMOS read/write failure Bad motherboard
  • 1 – 1 – 4 BIOS ROM failure Bad BIOS chip
  • 1 – 2 – 1 Timer failure Bad motherboard
  • 1 – 2 – 2 DMA failure Bad motherboard
  • 1 – 2 – 3 DMA failure Bad motherboard
  • 1 – 3 – 1 Memory refresh failure Bad memory
  • 1 – 3 – 2 64K memory failure Bad memory
  • 1 – 3 – 3 64K memory failure Bad memory
  • 1 – 3 – 4 64K memory failure Bad memory
  • 1 – 4 – 1 Address line failure Bad memory
  • 1 – 4 – 2 Parity error Bad memory
  • 1 – 4 – 3 Timer failure Bad motherboard
  • 1 – 4 – 4 NMI port failure Bad motherboard
  • 2 – 1 – 1 64K memory failure Bad memory
  • 2 – 1 – 2 64K memory failure Bad memory
  • 2 – 1 – 3 64K memory failure Bad memory
  • 2 – 1 – 4 64K memory failure Bad memory
  • 2 – 2 – 1 64K memory failure Bad memory
  • 2 – 2 – 2 64K memory failure Bad memory
  • 2 – 2 – 3 64K memory failure Bad memory
  • 2 – 2 – 4 64K memory failure Bad memory
  • 2 – 3 – 1 64K memory failure Bad memory
  • 2 – 3 – 2 64K memory failure Bad memory
  • 2 – 3 – 3 64K memory failure Bad memory
  • 2 – 3 – 4 64K memory failure Bad memory
  • 2 – 4 – 1 64K memory failure Bad memory
  • 2 – 4 – 2 64K memory failure Bad memory
  • 2 – 4 – 4 64K memory failure Bad memory
  • 2 – 4 – 4 64K memory failure Bad memory
  • 3 – 1 – 1 Slave DMA failure Bad motherboard
  • 3 – 1 – 2 Master DMA failure Bad motherboard
  • 3 – 1 – 3 Interrupt controller failure Bad motherboard
  • 3 – 1 -4 Slave IC failure Bad motherboard
  • 3 – 2 -2 Interrupt Controller failure Bad motherboard
  • 3 – 2 – 4 Keyboard controller failure Bad motherboard
  • 3 – 3 – 1 CMOS battery failure Bad CMOS battery
  • 3 – 3 – 2 CMOS configuration error Incorrect setting
  • 3 – 3 – 4 Video memory failure Bad video card or memory
  • 3 – 4 – 1 Video unit failure Bad video card or memory
  • 4 – 2 – 1 Timer failure Bad motherboard
  • 4 – 2 – 2 CMOS shutdown failure Bad motherboard
  • 4 – 2 – 3 Gate A20 failure Bad motherboard
  • 4 – 2 – 4 Unexpected interrupt Bad processing
  • 4 – 3 – 1 RAM test failure Bad memory
  • 4 – 3 – 3 Timer failure Bad motherboard
  • 4 – 3 – 4 RTC failure Bad motherboard
  • 4 – 4 – 1 Serial port failure Bad motherboard
  • 4 – 4 – 2 Parallel port failure Bad motherboard
  • 4 – 4 – 3 Coprocessor failure Bad motherboard or CPU.
  • 9 – 2 – 1 Video adapter incompatibility Use a different brand of video card

Award BIOS Beep Codes

Award BIOS uses beeps of varying duration. A long beep lasts for 2 seconds while a short beep lasts only 1 second. Award BIOS also uses beeps of different frequency to indicate critical errors.

If an Award BIOS detects that the CPU is overheating it may play a high pitched repeating beep while the computer is running. BEEP CODE MEANING POSSIBLE CAUSE 1 Long, 2 Short Video adapter failure Bad video adapter Repeating (Endless loop) Memory error Bad memory or bad connection 1 Long, 3 Short Video adapter failure Bad video adapter or memory High frequency.

Beeps (while running) CPU is overheating CPU fan failure Repeating High, Low beeps CPU failure Bad processor.

Long beep coming from my CPU

Hi Simon,

Your computer is performing a beep code, the long beeps indicate to the memory or RAM.

The problem is your memory, if the CPU casing has never been clean for such a long time it might build some dirt that may cause the lack of performance of the computer, check your memory on the memory slot inside your CPU casing.

Here is what you can do to fix the problem:

NOTE: First of all before you open your CPU casing shut down your computer and pulled out the power cord in the CPU case, then touch the casing for about a second to remove all the static electricity on your body it’s for safety purpose,

Pulled remove your RAM in the memory slot, just carefully press down with your thumb the lock in memory slot in both ends to pull out the RAM.

DDR2 Ram

Then clean the contact parts of the memory (the gold parts) with an eraser, just don’t overdo it enough to make it look new again.

Ram Memory

Clean also the memory slot in your CPU case much better I you use a blower to clear away all the dirt that builds up in inside your CPU case. If you don’t have a blower the paint brush will do, just used a clean one and carefully brush all the dirt in the memory slot or you can also do it in the motherboard as well.

Ram Slot

Now put back the memory in the slot look carefully to the notch of the memory (the cut part) at the bottom part of the RAM, you must align it in to the slot matching the notch to the keys of slot in the motherboards, make sure that the lock of the slot in both ends are open, now after you align the memory to the slot you must press it with your both thumbs straight downwards, use some force so that it set the memory correctly, you can hear a snapping sounds in the lock clips indicates that the memory is set correctly, do not force to push down if the RAM is not fit in to the memory slot, the memory must not be position correctly.

Motherboard process to attach the Ram

Now that you have successfully returned the memory to the CPU, power on your computer first before closing the case and see if the computers works fine,

Computer working fine

If there is no display in the monitor after you boot up your computer, check again your CPU look carefully for the connection that may be accidentally untouched while during the process of removing the memory and also check your memory as well,

If the long beep is still there, remove again the RAM and used the other memory slot of the motherboard,

If the beep is still going on, then replace RAM it must be defective.

Hope this can help.

Regards,

Bert
