My system was running good for 2-3 years. It stopped booting.
On Power up, it starts beeping and gives sequence of 8 beeps.
That means 'display memory read write failure' with an AMI bios.
It has onboard video card, audio card, etc.
I even tried with an external video card but still beeps.
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.
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 the
board itself).
Trieid with one of my 2 x 256 mb rams and
tried with replacing the other and still 8 beeps.
Then likely whats driving the ram has
failed, so its a dead motherboard now.
It has AMI BIOS 686 @1999 BB48 1930
Anyways I do not know what these numbers mean.
Doesnt matter.
As a final resort took out the mother board to see if I
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.
ahh I forgot to mention this. Since few days it started giving problems
in booting but after few times of power on and off used to boot.
Makes it sound like a bad joint or cracked
trace has developed or a bad cap.
The last time, I went to advance bios setup and disabled the System
memory cacheable which used to be 32k. Immediately after that it
started giving video memory problems and finally now 8 beeps.
What other alternatives are left and whatelse can I try.
Worth trying another power supply if you can do that easily,
but its much more likely the motherboard has failed.
Any help is very much appreciated.
