Regretting Mac Purchase - OS X Freezing Issues

Hi all,

I've been having freezing issues with OS X Leopard 10.5.3 that have been happening since 10.5.0. Every day (not exaggerating - literally every day) my Mac freezes for about 15 seconds, unfreezes for about 5, and then freezes again for 15, etc.

Here is a video of this basically happening:
http://www.viddler.com/explore/markbao/videos/6/

I can move the mouse, but clicking and keyboard usage is backed up, such that if I keep typing when it is frozen, it will show what I have typed when it unfreezes. Activity Monitor always shows kernel_task as the problem, taking up the entire CPU when it is in these 15 second freezing cycles, which doesn't really help.

Sometimes this goes on for about 10 or so cycles and then it just completely freezes, sometimes it's completely frozen after just one. In either case, the only way to fix it is to force restart, as I had done in the video.

Specs: MacBook Pro 15.4" 2.4GHz Penryn (Early 2008) - No, I do NOT have Parallels installed. OS X Leopard 10.5.3. Apple Hardware Test passed, no issues.

Any ideas? Thank you!
 
Have you looked at Activity Monitor to see what's running and using resources?

Yes, updated post to reflect that. Activity Monitor shows kernel_task as taking up the entire CPU, which doesn't help since kernel_task is basically the system running. Thanks for the reply.
 
To be fair, you modified your dock and you should take haxies into consideration when you have problems. I also see other transparencies that are not stock OS X.

Yes, I did change my dock background, but this has been a problem far before I did that. I don't know what other transparencies are non-OS X, though.

Thanks for the reply.
 
Why did you not return it to Apple when the problems started? Had you done so in the 14 days after you purchased it you would have got a brand new one, or a full refund.

This does sound like a hardware issue, so return it to Apple and I'm sure they will fix it. Have you attempted a reinstall? Is your RAM third party? Have you run the Apple hardware test to check for errors?

Sorry about that, I just looked at the video again, I misunderstood what I saw, I only notice the dock changes. You could have faulty ram installed. Yes Apple could have given faulty ram from the factory. If you are certain it's not ram you should definitely get in touch with Apple. Sorry that you are having difficulties, I know how that feels to get something new and it's not working well. Don't lose faith in the Mac experience as the OS is the best out there but this is a hardware issue, keep us updated.

3rd party RAM? Stock RAM?
Does it do it when you're logged in as another user?

No 3rd party RAM. This is a stock machine.

Don't have another user, can't work in another user. Maybe will try leaving it on overnight though.

Thanks!

Haven't attempted reinstall yet. Don't want to go to that, but I'm expecting it will.

Not a RAM problem.

Will run HW test right now.

I can't send this in - I work on this machine daily. Thanks for your suggestions!

:confused: Why can't you just create a different user account and use it for some non-work activities and see if the problem still exists? The way you worded your original post, it sounds like the issue occurs regardless of your open application.

Run an Apple Hardware Test.

Insert your install disc #1 and restart holding down "D".

Thanks. I did so, returned that there were no issues found with HW. Definitely SW then, so I'm somewhat happy.

This happens once every 20-24 hours, and I do work on this laptop. Thanks, though.
 
About this Mac > More Info > Software > Logs > System.log and error log

Might see a dyld cache retry or samba error happening when the system is freezing for that period.

Or might be one of the machines where spotlight has been hanging.

Thanks. At the end of my video, I recorded some futile attempts to catch what was going on in Console, :p. Didn't find anything suspicious.

The ones I mentioned were the biggies, have you done the font validation and font cache scrub yet?
 
Run Onyx and do a system cleaning.

If worse comes to worst, do an archive-and-install reinstall. It really doesn't sound like a hardware problem.
 
Alternatively, install the Developer Tools and use the Shark tool to run a system trace when the machine begins to freeze.

Shark will let you see a detailed breakdown of where the kernel is spending its time.
 
I've had a similar issue come up with one of my machines.

So I got sick of it and I'm making Apple "repair" it.

Create one and use it.

The point of this troubleshooting step is to determine if the problem is system-wide or relegated solely to your user. This helps narrow down the expansive list of variables that effect machine performance.
 
Check system log for disk errors

I have seen similar behaviour with the system hard disk going bad. The error rate slowly increased to make the problem increasingly severe.

check the system log for errors logged by the kernel.
