Since updating to 10.2 on an iMac graphite 400 mHz, I am having hard crashes frequently and unlike any I've had before. A couple of things will happen:
1) If I try to access the "screen effects" pane of the system prefs, the finder becomes unresponsive. The cursor still moves, but nothing else will happen.
2) If the computer is inactive for a long period of time, it will become inactive. If it goes to sleep, it won't wake up, so long as it's been asleep for some time. If sleep is turned off, it just becomes unresponsive as in number 1.
3) Sometimes when I reboot (particularly after a crash), the hard drive will spin up but the screen stays black. I believe the system is loading, because after the hard drive stops spinning, I can press "power" and then "return" and the computer will turn off, just as if it is at the login screen.
Thanks for any help.
