Hi everyone, thanks for your help.

My mac gets a grey screen and a box in the middle that makes me do a hard restart once in a while. I figured out how to access the console error logs but can't fix them. Help me, please!

Thanks for your help!

First, welcome to Geeks-To-Go.

Secondly, did you do an in place upgrade to Leopard or did it come pre-installed?

Hello Artagnan21,

Do you have the OS X disc that came with your machine? There should be one that says "Hold "D" to startup Diagnostics mode." Run that, and run the extended test. By reading the error logs, I hate to say but it looks like your hard drive maybe going. Especially when you mentioned the box on the gray screen. If its the folder with the "flashing question mark", its having a hard time finding the os on the drive. But also in the error log it mentioned:



HFS is part of the Mac OS Filing system. And looks like you have files beginning to corrupt.

I wish I had better news for you. If your machine is still under Apple Warranty you should have no problem getting the hard drive replaced.
