OK, I understand you guys and thanks for reading this.
I don't want to "bitch" on anything here.
I have this problem with that particular upgrade and
I'm looking for to save it from trashing it....

Without a willingness to discuss details all I can say is request some tech support from Giga and or send it back for warranty repair. They can tell if it has a problem.

Yes, that's what I did 2...

THrow in some information, like, where it sits? Is it off the ground or carpet? Does it have plenty of free airspace around it? Is the room of reasonable temperature? Do all the G4s fans turn, even...

G4 AGP Digital Audio (originally 466mz)

This cpu upgrade (G-celerator#5-1212G) is getting so hot
that the machine will first reports errors and...

The culprit is the GIGA 5-1212 CPU upgrade!
All these random problems are caused by
the cpu overheating.
I had to test with a 2nd G4 466 to be sure.
By putting the card voltage down from 6.0v to...

Which Apple hardware test version did you use?
Version 1.1

Will try to do more testings...

Well, finally got an apple hardware test cd!
Reports:
Logic board Error detected
Error code
SCC/3/7

Does it needs to have the logic board replaced?
If so, where to get it?
And thanks again!

Yeah, thanks!
But why is Explorer running OK on the other machine?

Here's another excerpt from the latest freeze:

Well, thanks for your reply!

No bad blocks on the drives.(Norton verified)
Dimm is ok.(dimm 1st aid & techtool)
PCI ATA card is a Sonnet tempo ATA 133.(no scsi)
OS 9.2.2 clean install was done...

Thanks!
As a new attempt, I've installed macsbug!
At the first crash it reports:
your heap is probably corrupt...

What is the heap?

The freezes still happen with extensions off.
OS9 is also installed on a different disk and
it still happens booting from there.
Is there a way to check the pci board?
Could it be the video card?...

all ram, motu driver, extension conflict meticulously
checked.
The 2nd mac G4 AGP is running fine + same set up.
Could it be the pci board having an intermittent
problem?
or psu voltage drop...

What would be the sign of a failing logic board?
What would be the symptoms of a bad pci board connection?

Humm,
the freezes are back!
So this is not the soundcard.

The memory was checked adding the 512 stick

Running os 9.2.2.
Explorer is working allright in the G4 500 AGP.

Will do.

Today while booting, it froze + this message:
Sorry, a system error occured
"apple audio extension"

As I was watching a streaming quick time video from
a web site, the computer froze again.
So, it seems to have something to do with caching
whether with memory or disk.
The problem was existant...

This morning, the machine stopped booting
after the icon of the first drive appeared.
Had to reboot a 2nd time to completion.

OK here's my report:

1-Try booting into Open Firmware
