My computer freezes
on Sep 4, 2006 at 6:23:56 pm

Hi, I've got a serious problems.
My G4 MDD 2x1.25GHz freezes every now and then, happens in any
application.
Sometimes after a couple of minutes, sometimes after a few hours.
Since I'm right now working on heavy rendering in FCP and
AfterEffects it's not very fun.
It all started when I had done a few changes in the computer.
New graphic card, installed an extra internal HD, updated to FCP
studio and OS 10.4.
I don't get kernel panic, the computer just freezes.

I have rebooted in safe mode and repaired permissions serveral times.
I have formatted the HD and reinstalled everything twice.
I've tried master/slave and cable select on my HD's.

Any clues?

Erik

Have you run hardware test, you may be having a problem with bad ram... or some other hardware difficulty...

I'd try that and see what that tells you...

My G5 did a similar thing few a months ago... turns out that the fan on the graphics card died. That caused the graphics card to overheat and freeze the display. That's irony for you! (Overheat/Freeze)

Hope that helps.

RAM or FAN.
Since the graphics card is new I went for RAM.
Two new 1GHz and it seems stable.
If it stays that way I'll add my old 2x512Mb RAM and see what happens.
Then I'll know if it's because of the RAM's.
By the way, the hardwaretest said everything was alright.
Thanks
Erik

I have the same computer and it started doing the same dang thing about 3 weeks ago. I noticed it after "upgrading" to 10.4.7. Initially, i thought the problem was iTunes, so i stopped using iTunes. The problem didn't go away, so i disabled the nifty desktop picture changer. Now it's worse than ever!

Sonnet Tempo Trio
2 Seagate 300GB HDDs plus the original 80GB HDD
2 Kingston 512MB memory sticks
2 displays - Apple 17" cinema & Envision 19" CRT

What I've tried:
Zapped PRAM
Reset CUDA switch
stopped using iTunes (trashing prefs didn't help)
disabled desktop picture changer
trashed display prefs
TechTool Pro & defrag
i've run disk utility about a thousand times

none of this stuff helped. I haven't started yanking hardware, but that may be the next step.


I didn't notice this until i upgraded to 10.4.7 and iTunes 7. And my problem is that it's intermittent. Like you said, sometimes it runs all day with no problem, sometimes it freezes after 10 minutes.

If this keeps happening, I'm going to fidget with the memory and possibly a different fan.

Like you, I bought this thing because I have things I need to do on the computer. If I can't keep it from freezing, I may as well get a Dell.

Please keep me posted and let me know if you discover anything.
