For some reason, my early '06 iMac has decided to start beachballing all the time when I've never had a problem before. At first, it seemed to happen just with internet-related apps (Safari, Mail etc) but now it's started spreading..I will get the beachballing while using Ableton (Infrequently) and really often while using the finder. It doesn't cause me to restart, but it will make the computer unusable for 10-15 seconds- when this is happening several times an hour when you're working, it drives you mad! I've got plenty of RAM (1.5GB) and have noticed that it only started happening after the 10.4.10 update. Is anyone else having these problems? I've checked my page in/outs and have got 48,610/2,741. I've got plenty of HD space left and when the beachballing happens, the CPU isn't affected (ie. no programs are causing 100% CPU load) I'm really struggling to think of what the problem is. I'm hoping it's not hardware-related. I can't really afford to wait a few weeks for Apple to fix it. Thanks for your help.
