HELP TO TROUBLESHOT.

What are you formatting ? Have you changed the RAM. Does tour system work in its original configuration ? You do not say what the pattern of the beeps is. Before the display disappears, is there a message sent to the screen ?

Whenever a recoverable error occurs during POST, the BIOS displays an error message

describing the problem (see Table 53). The BIOS also issues a beep code (one long

tone followed by two short tones) during POST if the video configuration fails (a faulty

video card or no card installed) or if an external ROM module does not properly

checksum to zero.

An external ROM module (for example, a video BIOS) can also issue audible errors,

usually consisting of one long tone followed by a series of short tones. For more

information on the beep codes issued, check the documentation for that external

device.

There are several POST routines that issue a POST terminal error and shut down the

system if they fail. Before shutting down the system, the terminal-error handler issues

a beep code signifying the test point error, writes the error to I/O port 80h, attempts

to initialize the video and writes the error in the upper left corner of the screen (using

both monochrome and color adapters).

If POST completes normally, the BIOS issues one short beep before passing control to
the operating system.

Yu will need to determine which BIOS you have a see below
The computer beeps several times
If you hear several beeps from the PC speaker, it means that the computer failed its power-on self test (POST) because a problem was detected. The POST is a procedure that tests several components such as power, BIOS, CPU, memory, and video. Only if all those tests pass, the computer will then allow the operating system to load. But if one or more of these tests fail, beeps indicate a problem and the boot process is halted. These errors are a little more difficult to troubleshoot.
To diagnose the problem, listen to the beeps carefully and write down the sequence. Is it one long beep? Is it several short beeps? How many? Once you have the beep sequence documented, you need to find out what it means. What BIOS do you have? When you first turn on the PC, look at the top of the first screen to find out. Common BIOS types are Award, Phoenix, and AMI.
Award:
1-2-2 Indicates a video error has occurred and the BIOS cannot initialize the video screen to display any additional information Any other beeps Most likely a RAM problemYou can find more detailed information about Award error messages on Award's web site.
Phoenix:
1-2-2 Indicates a video error has occurred and the BIOS cannot initialize the video screen to display any additional information 1-2-2-3 BIOS ROM Checksum 1-3-1-1 Test DRAM Refresh 1-3-1-3 Test Keyboard Controller 1-3-4-1 RAM Failure 1-3-4-3 RAM Failure 2-1-2-3 Check ROM Copyright Notice 2-2-3-1 Test for unexpected interrupts 1-3-4-3 RAM FailureYou can find more detailed information about Phoenix error messages on Phoenix's web site.
AMI:
1 beep Refresh failure 2 beeps Parity error 3 beeps Base 64K memory failure 4 beeps Timer not operational 5 beeps Processor error 6 beeps 8042 - gate A20 failure 7 beeps Processor exception interrupt error 8 beeps Display memory read/write failure 9 beeps ROM checksum error 10 beeps CMOS shutdown register read/write error 11 beeps Cache memory badYou can find more detailed information about AMI error messages on AMI's web site.
If you get beep errors, you should try to think what happened right before they started. Did you add a new piece of hardware? If so, it might be faulty or not installed right. Remove it, then try again. If everything is fine without the hardware, try to reinstall and configure the hardware again. If that does not help, try exchanging it and see if that corrects the problem. If the error persists, narrow it down systematically. Remove everything but the CPU, memory, keyboard, and video card, then boot again. Does the error still occur? If not, then add one piece of hardware and try again. Repeat until one new component causes the error and you now know who the culprit is. If yes, then reseat your CPU, memory and video card and try again. If the error still happens, try replacing the CPU, video card and memory one by one to see if one of them is the troublemaker. If that does not help, you could have a bad motherboard. Check the motherboard carefully for any signs of damage. Also check for shorts, a metallic object could have found its way onto the motherboard, or the motherboard is not installed correctly and touches the case somewhere.

Hi John. If you already swaped the Memory, it's the video card. I'm giving you what the beep means according to the different types of BIOS, because basically Ascent is a clone PC. I hope it helps.
(you will have to open the computer to see the BIOS type.)

BIOS AWARD

1 long beep and 2 shorts -- Video error
2 short beeps -- non-fatal error.
1 beep corto -- OK.

BIOS AMI

1 short beep -- Memory error.
2 short beeps -- ECC error.
3 short beeps -- Memory error.
4 short beeps -- change atery
5 beeps cortos -- bad processor.
6 beeps cortos -- bad keyboard.
7 beeps cortos -- video memory bad.
8 beeps cortos -- video bad.
BIOS PHOENIX

1-1-2 beeps -- Problem with cpu/motherboard.
1-1-3 beeps -- Cmos issue.
3-4-1 beeps -- Video issue.

BIOS IBM

1 short beep -- Post normal, ok!.
2 short beeps -- POST error, will show on screen.
NO beep -- CPU issue or Expansion card issue
1 long and 1 short -- motherboard error.
1 long and 2 shorts -- Video issue.
1 long and 3 shorts --EGA video issue.
3 longs -- Keyboard error.

You really aren't giving much info, so here are some beep - codes, also make sure nothing came loose on the motherboard or other components ( do this ONLY if you know how ) Safety first.

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

Hi

THe most common beeps that you will encounter 95% of the time in repairing PC's are:

1 beep - computer ok
continous beeps / long beeps - memory error
continous short beeps - bios boot block/corrupted bios
1 long beep followed by 3 short beeps - video card error


or this might help

you can check out this list



AMI BIOS

1 short - Computer ok
2 short - RAM failure
3 short - Parity RAM failure
4 short - System timer failure
5 short - Motherboard failure
6 short - Keyboard controller error
7 short - CPU failure
8 short - Video RAM failure
9 short - ROM BIOS error
10 short - CMOS read/write error
