No display problem for intel D865GSA board


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 ?
From the manual
http://download.intel.com/support/motherboards/desktop/d865gsa/sb/d5600601us.pdf

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.

Er-290 wont stop beeping


Step 1:
The beeps are post during post the very first work is done by the ram, all the memory in the ram is first transferred to the hard disk, and remains 1 short beep : Normal POST - system is ok
2 short beeps : POST Error - error code shown on screen

No beep : Power supply or system board problem
Continuous beep: Power supply, system board, or keyboard problem

Repeating short beeps: Power supply or system board problem

1 long, 1 short beep : System board problem
1 long, 2 short beeps: Display adapter problem (MDA, CGA)
1 long, 3 short beeps: Enhanced Graphics Adapter (EGA)
3 long beeps : keyboard card

I still did not find beep code that match your problem..

Anyways here are the common beep codes for your motherboard.. it might help you too.
1. No beep - no reaction, the mother board is dead, power supply problem, processor and or ram problem.
2. 1beep - board is working fine.
3. One long beep then it shuts down - cpu problem, your processor is not working or missing.
4. 1short beep - system boots normally
5. 2short beeps - CMOS setting error.
6. 1long 1short beep - dram error
7. 1long 2 short beep - video card or monitor not connected
8. 1long 3 short beep - keyboard error.
9. 1long 9short beep - ROM error
10. Long beep - memory card is missing or not connected
11. Short beep - power supply error
12 Four beeps - there is no fan detected on Fan1 or Fan2 header. make sure to attach or reset CMOS bios to factory setting.


Hope this gave you an idea of your problem..

Much appreciated if you rate this help..thanks..

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
11 short - Cache RAM error
1 short, 3 long - Memory failure
1 short, 8 long - Video adapter failure

Check board/chipset makers website for more infomation.

AWARD BIOS

1 long - Memory error
1 long, 2 short - Video error
1 long, 3 short - Video failure
Continuous beeps - Memory or video failure

note that AWARD relies on motherboard manufacturers to develop their own beep codes - the above are only their own internal codes. You will need to refer to your own manual for an explanation of precise codes.


Standard IBM beep codes.

No beep - Power supply or motherboard failure
1 short - System is ok

Processor upgrade


Need to look at the motherboard specs along with the processor "Socket". It will usually be a 754 or 939 depending on what your motherboard says. I wouldn't try too fast and set yourself up for disappointment. I would upgrade the RAM before the processor.
