I have a macbook pro purchased in December 2009. In the last month, the spinning ball of death starts if I am in Pages, on the Internet, in Adobe Acrobat, anywhere. This could start immediately after startup, or take a half hour before it begins. Once this starts, the ball spins on every action I take. I have run system utilities almost daily, started in save mode, reinstalled the OS, done a FSCK -FY after starting in system mode, nothing helps. I blew the dust out of the hardware. I tried to do a hardware diagnostic on startup (holding down the D key before the grey screen appears) but the computer ignored this and went through its startup process. How can I find out what is going on with my computer?
MacBook
Pro, Mac OS X (10.6.8)
