    Hi all,

    Specs on my computer as follows:

    Model Name: Mac Pro
    Model Identifier: MacPro1,1
    Processor Name: Dual-Core Intel Xeon
    Processor Speed: 2.66 GHz
    Number Of Processors: 2
    Total Number Of Cores: 4
    L2 Cache (per processor): 4 MB
    Memory: 8 GB
    Bus Speed: 1.33 GHz
    OSX - 10.6.8
    Norton Security Suite for Mac

    For about a month now, I have become the beach ball lady. It doesn't matter what application I run, there are times when any application I choose will hang after a while....Final Cut or Calendar or Finder. it seems that the beach balls are more frequent if the computer goes to the screen saver or black screen mode. A reboot fixes the issue, but only for a while. Norton has shown no issues. Any ideas?

    Hmm... Hard Drive dying causes such spinning balls.

    Try booting in safe-mode (hold shift at startup chime). If problem persists, I'd look into the HD.

    If your hard disk is fine, I'd venture to suggest that Norton is the problem.
