Hey guys.. After a flawless year with my newest iMac, I've developed a problem.. It started with the spinning beach ball of death whenever I'd load Safari or Firefox. Neither would work. A restart would put the computer into blue screen. If I turned it off, let it sit, and then back on, it would boot, but still would hang when opening Firefox.. Restored with an erase and install. Worked ok after the install, but now iTunes is slow and the beach ball shows up, a restart comes up with a desktop but no icons, dashboard, etc.. Tried running the Disk Utility, and it says the HD appears to be ok.. Fixed permissions which said there were all kinds of permission errors, but appears to be squared away now.. Still running slow, and iTunes is giving me the beach ball again... Any idea's?
