My pc beeps when stars and the does not start completly it continues to give that beeping and the monitor does not display anything


The beeps in your computer at boot up mean that there is an hardware.
Every number and lenght of beep is a code that indicates where the error is. You should refer to your producers webpage to "translate" the code in the cause of boot failure

Does no show display and bios beeps once then three time then three more time then again once more.


Hi,
Regarding the Beep codes try removing the Memory Rams one at a time and see if the computer will turn On properly with 1 RAM at a time, if you have an expansion video card, try removing the video card and use the internal video on the motherboard see if it will boot without any errors.
What you are experiencing is a no POST issue, you do not see the BIOS as you mentioned,remove anything expansion on the motherboard and do the RAM Dance, try One RAM at a time as mentioned and try each RAM on all the Memory RAM slots Available to find out if it will be a RAM causing the issue or possible a bad Memory Slot on the Motherboard.

Inspiron 531s will not boot up, keeps beeping, saying it is in power save mode. How do I fix the problem


System Beep Codes The Inspiron™ 531 / 531s system can emit a series of beeps during start-up if the display cannot show errors or problems. These series of beeps, called beep codes, identify various problems. One possible beep code consists of repetitive three short beeps. This beep code indicates the computer encountered a possible system board failure.
The series of beeps has a 3-second delay before it repeats. The series and delays continually loop until you press the power button.
Code Description Suggested Remedy 1 BIOS ROM checksum in progress or failure System board failure; covers BIOS corruption or ROM error 2 No memory modules detected
  1. If you have two or more memory modules installed, remove the modules, reinstall one module, and then restart the computer. If the computer starts normally, reinstall an additional module. Continue until you have identified a faulty module or reinstalled all modules without error.
  2. If available, install a good memory module of the same type into the computer.
  3. If the problem persists, contact Dell.
3 Chipset error (North and Southbridge chipset, DMA/IMR/Timer Error for Intel® platform); chipset error System board failure. Power LED is blinking amber. Time-Of-Day Clock test failure Gate A20 failure Super I/O chip failure Keyboard controller test failure 4 RAM read/write failure
  1. Ensure no special memory module/memory connector placement requirements exist.
  2. Verify the memory modules you are installing are compatible with the computer.
  3. If the problem persists, contact Dell.
5 Real time clock failure. Possible battery failure or system board failure.
  1. Replace the battery.
  2. If the problem persists, contact Dell.
6 Video BIOS test failure Video card failure 7 CPU cache test failure Processor failure

Motherboard beeps three times, computer won't boot up


Your computer is experiencing memory problems. Turn power off, remove and reseat the memory chips, and try it again. If not successful, try different memory chips. Also could be power supply problem

At POST I get 2 short beeps


it depends on the bios chip maker Here's some other beep codes:

for Award and Phoenix BIOS:

1 short beep: Normal
2 short beeps: CMOS error
1 long and 1 short beep: DRAM error
1 long and 2 short beeps: Video card error
1 long and 3 short beeps: Keyboard error
1 long and 9 short beeps: ROM error
Long continuous beeps: DRAM not installed correctly
Short continuous beeps: Bad power supply


AMI BIOS:

1 short beep: DRAM flash error
2 short beeps: DRAM ECC check error
3 short beeps: DRAM detect error
5 short beeps: CPU error
6 short beeps: Keyboard error
8 short beeps: Video card error
9 short beeps: ROM error
1 long and 3 short beeps: Bad DRAM
1 long and 8 short beeps: Video card error


Invoking Beep Codes

.

If the computer is actually functioning and the computer beeps continuously, then there is a problem with a voltage on the power supply being incorrect or the CPU overheating. IMMEDIATELY go into the BIOS and check CPU temperature, fan speed and voltages

**********************************************
BIOS Beep Codes

Annoying isn't it? You have built your computer you switch it on and then nothing happens except a few beeps from the PC speaker. Frustration sets in as you try to figure out what is wrong with it. If you didn't already know the computer has already told you the problem. It can't speak of course but it can direct you to the problem. Its all in the beeps. The BIOS can recognise when the problem occurs and sends a signal out to send a certain amount of beeps through the speaker. These beeps then tell you the location of the problem.

Unfortunately not all the BIOS' use the same codes as each other. Two of the main BIOS manufactures AMI and Award (now Phoenix) have different codes for there errors.

AMI BIOS

# of Beeps Error Description
1 Refresh Failure The memory refresh Circuitry is faulty
2 Parity Error Parity error in the Base (1st 64K) of memory
3 64K Base Memory Error Memory error in the base memory (1st 64K)
4 Timer Not Operational Timer 1 is not functioning (also caused by error in base memory)
5 Processor Error CPU error
6 8042 Gate A20 Failure Unable to switch to protected mode
7 Processor Exception Interrupt error The CPU on the CPU card generated an interrupt error
8 Display Memory Read/Write Error Video adapter is missing, incorrectly seated or has faulty memory
9 ROM checksum error The ROM checksum does not match that of the BIOS
10 Coms Shutdown Register Read/Write The shutdown register for coms RAM has failed
11 Cache Memory Bad The cache memory test has failed. Cache memory will be disabled. *** DO NOT enable it ***


With the first 3 beep codes, its well worth re-seating the memory just to make sure that it's in correctly. 8 Beeps is probably the most common in my experience. Can be caused by a badly seated Graphics card. If you have re-seated it then check with another Graphics card in the board.

Always check for loose components before sending the board back as this is the main cause of errors on the POST.



Award BIOS

Award states that they now only use one beep from there BIOS. This beep is one long beep and then two short beeps. This indicates a graphics card problem. Any other beeps should be treated as a RAM problem first and then the board sent in to be inspected.

The reason that the Award BIOS only uses the beep code for display problems is that it tries to display the error on-screen if at all possible. If the BIOS cannot initiate the display adapter then this causes the BIOS to make the beep code for a display error, which must be corrected before any other errors can be determined. Memory Test fails and hard disk failures etc will all be displayed on screen

IBM BIOS

The IBM BIOS works with Short and Long beeps as well as the Award BIOS. However the IBM one does still have codes to work from.

Beep Code Error
1 Short Beep Normal POST, System booted OK
2 Short Beeps POST Error - Code on Display
No Beep Power supply or Motherboard error
Continuous Beep Power supply or Motherboard error
Repeating short beeps Power supply or Motherboard error
1 short, 1 long beep System board error
1 long, 2 short beeps Display adapter error (MDA/CGA)
1 long, 3 short beeps Display adapter error (EGA/VGA)
3 long beeps 3270 keyboard card
Phoenix BIOS
The Phoenix BIOS works on a slightly more complicated manor than the others. It does display an error code for you and produce a series of beeps. This BIOS produces its beeps according to the hexadecimal code the error produces. The Phoenix BIOS has many different codes for its possible errors and so many different beep codes. Rather than list the entire section here, I have provided a link to the official PDF file containing the codes and how they are derived.

Phoenix BIOS Post Codes

System board errors should be looked at by a specialist, Again always try to re-seat components to ensure they are in correctly. If necessary take all components out except for the RAM CPU and graphics card, then try the system. Re-seating components is the number one fix for getting past the POST screen. One badly seated components can cause the entire system not to function. so pick out your bios and follow the steps above to diagnose .hope this helps

Dell precision 3100 machine will not boot up


If your computer is beeping at you, 9 times out of 10 its going to be an issue with the memory or video. (more often the memory) Try re-seating both. If your still hearing the beep fest, below is a list of the most common beeps and what they refer to. This will help you to find out what needs replacing.

Long beep followed by 3 sequential short beeps. This issue is linked to your Graphic card configurations
Short beep followed by three sequential long beeps You are facing a system memory problem
Beep- PAUSE- Beep- PAUSE- Two sequential beeps This error is linked to your CPU
Three beeps-PAUSE-Three beeps-PAUSE-Four beeps You have an issue with the video memory
Three beeps-PAUSE-Four beeps-PAUSE-Beep This is linked to an error with your Graphic Card
Four beeps-PAUSE-Three beeps-PAUSE-Beep You have a system memory problem
Five short beeps You are facing a problem with your CPU
Long constant beeps It’s a system memory problem
Short constant and high-pitched beeps The temperature of your CPU is too high

3 beeps - Base 64 K memory failure

  • Reseat the memory.
  • Make sure that the contacts on the memory and the socket are clean.
  • Try removing one bank of memory modules at a time. Note: Some systems might need to have a memory module in Bank 0.
  • Try using RAM chips from the same manufacturer with the same part number and speed.
  • Check for a faulty memory module by trying the memory in a known good system.
  • Trying known good memory in the system.
  • Check the power supply and check for power fluctuations.
  • Swap the motherboard.
