Does not boot 8 beeps even after cmos clear

[aki2006]

My system was running good for 2-3 years. It stopped booting. O
Power up, it starts beeping and gives sequence of 8 beeps

It has onboard video card, audio card, etc

I even tried with an external video card but still beeps

I did all the things mentioned about checking the AMD chip if burnt
or chipped on corners etc., nothing of that sort and it seems to b
fine

Removed the memory and tried, as excepted no sound at all

Tried clearing cmos by jumpering to 1-2 and back to 2-3 etc
On this board 1-2 clears cmos and 2-3 default. (It is written on th
board itself)

Trieid with one of my 2 x 256 mb rams and tried with replacing th
other and still 8 beeps

It has AMI BIOS 686 @1999 BB48 193
Anyways I do not know what these numbers mean

As a final resort took out the mother board to see if I can take ou
or disable the onboard video card. No luck

ahh I forgot to mention this. Since few days it started givin
problems in booting but after few times of power on and off used t
boot

The last time, I went to advance bios setup and disabled the Syste
memory cacheable which used to be 32k. Immediately after that i
started giving video memory problems and finally now 8 beeps

What other alternatives are left and whatelse can I try

Any help is very much appreciated

Thank

Sounds like a bad mainboard. But before you trash it, try a different power
supply with it. -Dave

That means 'display memory read write failure' with an AMI bios.

It has onboard video card, audio card, etc.

Presumably you mean a video card.

That wont necessarily stop the POST test checking the onboard
video ram at boot time and failing the POST if it sees a problem there.

I did all the things mentioned about checking the AMD chip if burnt,
or chipped on corners etc., nothing of that sort and it seems to be fine.

Then likely whats driving the ram has
failed, so its a dead motherboard now.

Doesnt matter.

can take out or disable the onboard video card. No luck.

Yeah, its mostly disabled auto at boot time.

That doesnt necessarily stop it checking the onboard video ram
and it may be checking that first and may check the normal ram
later and that would have failed the check if it had been done too.

Makes it sound like a bad joint or cracked
trace has developed or a bad cap.

Worth trying another power supply if you can do that easily,
but its much more likely the motherboard has failed.

But seriously.

Thanks guys. That was prompt replies but did not help

Well keep asking because you're not getting anywhere "taking
out the mother board to see if I can take out or disable the
onboard video card".

Maybe you can make friends with a local techie.

Good luck.
