I see many users to confused on BIOS beep codes, so ill create a new topic with them (i search the forum for a topic like this but i didn't find anything, but if this topic exists just delete mine.)

AMI BIOS:
1 beep - System boot successfull
*1beep - Refresh failure - (NO VIDEO) memory refresh failure (bad memory)
2 beeps - Parity error - bad memory
3 beeps - Base 64K memory failure - bad memory
4 beeps - Timer not operational - bad motherboard
5 beeps - Processor error - bad processor
6 beeps - 8042 gate A20 failure - bad cpu or mainboard
7 beeps - Processor exception interput error - bad processor
8 beeps - Display memory read/write failure - bad video card or memory
9 beeps - ROM checksum error - bad BIOS
10 beeps - CMOS shutdown register read/write error - bad motherboard
11 beeps - Cache memory bad - bad CPU or motherboard
12 beeps - BIOS rom file incorrect size - The BIOS ROM file found does not match the size of the flash device
13 beeps - BIOS rom image mismatch - The BIOS ROM file layout configuration does not match image present in the flash device
5 short + 1 long beeps - Memory error - No memory detected in the memory slots.
6 short + 1 long beeps - Memory error - EDO memory detected in system
7 short + 1 long beeps - SMBUS error

AWARD BIOS:
1 short - System boot successfull
2 short - CMOS setting error
1 long 1 short - DRAM or M/B error
1 long 2 short - Monitor or display card error
1 long 3 short - Keyboard error
1 long 9 short - BIOS ROM error
*repeated beeps - DRAM error
*repeated short beeps - Power error
*Repeated high & low beeps - Processor is damaged/Overheated

any way thanks .. =) even thought it exist.. it would be a waste to delete this good article topic. I can refer here too for futere technical reference =). thanks .. well done .. goood job 

[NovJoe]

Good Thread and a Sticky for you guys  !

[vronks]

And When no beep happens? My mainboard it doesn beep anymore? Anyone here has a clue what problem could be happening?

[NovJoe]

Could be motheboard problematic or PSU not able to supply power properly.

Btw, please open a new thread for your question instead of posting in the stickies.

[nwheeler]

I have a P4N Diamond (AMI BIOS) that is beeping as follows...1 beep, pause, 2 beeps, pause, 1 beep.

This sticky doesn't cover all motherboards, so would it be possible for some experts to post updates so that all of the newer boards are also covered?

[mball]

I too have a beep code not listed with the P4N Diamond, I get 2 beeps then a pause the another two beeps. If I dont have the monitor switched on I get 3 beeps then a pause then another two beeps

[nelsinho2]

very, very good job man this is useful thanks

[Din]

Im not a man, however don't post in this thread, except if you have more beep codes to place in this thread

[NovJoe]

Dear Friends and Fellow Members,

In order to keep this thread clean and clear, I'm going to lock this sticky thread for good.

If anyone has ay updates, please kindly PM me or drop me a mail with your Forum Nick and I'll help you to add the info in.

Regards,
Joe Chow.

A new piece of useful info by djcs on hardware diagnostic testers:

Something that could be added to the beep codes forum

http://search.ebay.com.au/search/search.dll?from=R40&_trksid=m37&satitle=motherboard+tester&category0=

i have found them very helpful....
if you do a search on ebay for just motherboards, you can find isa and usb based testers too....
