My guess is try to re-seat your RAM. That means touching the side of the case first, then removing the sticks of memory and re-inserting them, making sure they are firmly pressed evenly into their DIMM slots (Listen for the click as the side tabs lock it into place).

If not, I'll go dig up a tech manual for that model and do some more research for ya.

BIOS Beep Codes
Whenever a recoverable error occurs during POST, the BIOS displays an error message describing the problem. 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.

Three beeps at POST (startup) may be caused by an issue with your video card. Check to make sure the video card is seated correctly. If you have another video card, you can try it to determine if the current video card is faulty.

Based on your description of your problem, my educated guess is that you have a problem with the system board or motherboard. Checking Compaq support site, it says that beeps are generally heard when a hardware device is not connected properly or has failed.

First thing to try is disconnect the keybaord and mouse and try to start the computer again. What we are trying to do is find out which hardware device might be involved. So start with the keyboard an mouse. If the computer still does not start, remove any periferal drives, like floppy or cd drives.

There are several beep codes, below are a few examples listed:

Beep codes common to HP and Compaq Desktop PCs The following beep codes are common to many HP and Compaq desktop computers. Use these codes first before referring to the other code lists. NOTE: Not all codes are shown. Beeps Description 1 short beep and 1 long beep Memory problem 2 short beeps and 1 long beep (repeats 5 times) Unable to initialize video or video card required but not installed 3 short beeps and 1 long beep CPU configuration error or CPU type is not compatible The following beep codes are common to many HP and Compaq desktop computers that can occur while restoring, flashing or updating the BIOS : Beeps Description 1 short beep Legacy floppy drive or CD/DVD drive not detected 2 short beeps Floppy diskette or compact disc not detected 3 short beeps Unable to start flashing (such as when missing a utility or BIOS image) 4 short beeps Flashing failed (checksum error, corrupted image, etc.) 5 short beeps BIOS recovery successful Try working on this solution and see if you can get the computer to start. Below is a link to a troubleshooting page from Compaq for your computer. This can be a good reference as well.

3 medium beeps on pc; repeating


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.

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

Hi,
i can help you with the Post-Code Beeps.
AMI Bios= 2 Beeps. Parity error In First 64k Ram. ( reseat Memory ) Post Failure 1 or more Of the Hardware test Have Failed.
IBM Bios= 2 short Beeps. Post Error ( Memory Possibility ) review screen for details.
AWARD Bios Codes = 2 Short Beeps. Any Non-Fatal Error. Enter CMOS setup to reset.
I,d go for Memory ( RAM ) But first enter bios setup Usually F2 Or Delete escape et,c. Reset to defaults, and see if that solves your Problem.
