Need help fixing my OS X!

[freaky]

For the past few problems I have been having some really bad problems with OS X. I don't have an entire day that I can devote to wiping out my hard drive, reinstalling OS X along with all of my apps and am hoping someone can help me fix this.

Here is a list of problems that I have:

When selecting Apple then Restart it just logs me out
When going to Apple then About This Mac and closing the window it logs me out
When going to Apple then About this Mac then More Info it logs me out
When opening the Force Quit window and closing it, it logs me out
Certain apps that I go to open just automatically close and do not appear in the Activity Monitor task list

Here is what I have tried:

Running verify/repair disk permissions using the Tiger DVD.
Running Cocktail and all the scripts it runs
Runnin Yasu

Anybody have any ideas? I HAVE to fix this ASAP!!!!!!!!!!

Onyx is another good system cleaner.

Because your problems are so diverse, it sounds like a re-install would be a good idea. You don't have to to do that now, so see if the problems persist on a new account. If they do, then you've got a system-level problem that may be hard to fix. If they don't, then try to migrate to that account, until you can re-install.

Yes, it may be possible to successfully fix your problems, but in that time, you could easily have done a re-install.

I just spent an entire day reformatting my drive (writing zeros to it) and reinstalling all of my software. My machine is doing the strange things that I posted above and it is driving me nuts. Does anyone have any other suggestions that I should try?

I created a new user account and logged into it and the same exact problems occured so it's not just my main account that's having these problems.

Is there some sort of error log that I can check to see what errors are occuring?
