Logic quits during startup

[velvet]

I have a serious problem for past few days. 90% of times when I try to open Logic the window with Logic logo opens and it says that itis Setting Up Memory buffers and after 2-3 seconds it closes and logic does not open. This happens either I click on the project icon opr on the "main" icon in Applications folder.

I did not change a thing (no new plugins for more than month - tahat was the UAD-card...), no new drivers, etc. I am using Logic everyday and my DualG5 is used only for music.

This was happening when I was on 10.4.5 and Logic 7.1.1

 

I reinstalled the system yesterday and made a fresh OSX installation including fresh installation of plugins, Logic etc... It seemed to be OK first but after a few hours of use it's happening again.

 

I use WD Raptor HD for OSX (the "upper bay"), another WD Raptor HD for audio (Lower bay).

Than I have a PCI-X SATA card from Firmtek and 3 more Hard Drives are connected to it (Samples and Data storage)-they are not inside G5....

 

I dunno, can this be caused by really hot weather theese days in my area? I mean seriously-WD Raptors are known for producing a lot of heat and I have two of them inside the machine.

Really unpleasant situation. Clients are waiting for mixes and I can not work

 

If anybody has an idea please let me know.

Thank you.

Have you tried starting Logic without the CoreAudio driver (hold control at startup)? Have you tried going into the AU Manager and unchecking plug-ins to see if any 3rd party plug-in could be the culprit?

Hi David. Yes I did. Logic quits 90% of times before the dialogue box with the question : Start without core audio (or similar) appears. If it comes to that point than it opens and runs. But that is the same as if I did not hold the ctrl. It is probably not my audio I/O related. The fact is, that the "dissapear" happens really quickly, after 2-3 seconds I click on icon to open Logic. And all I can see always in the "startup" Logic window (the one that appears right after you double click on Logic icon) is the information : Setting up Memory buffers. and than nothing, a big n-o-t-h-i-n-g

 

So it probably has to do something with setting up memory buffers or with the process that comes after "Setting up Memory buffers" during loading of Logic.

 

I did all tests with Tech Tool Pro. All passed. And again- I did totally fresh installation of OS X, Logic, plugins, drivers..

 

I am really confused. Maybe bad memory module? But Tech Tool pro tested it...

Well, just to make sure, take any additional RAM out and leave the original in.. see if it behaves better?

 

Since even after a fresh install the problem subsist, it could be hardware related.
