My iMac suddendly won't start up....kind of. It froze the other day when displaying the screensaver and now it won't boot.
It starts with the chime and the light gray screen with the Apple logo and the spinning "activity wheel".
Then the screen turns white and just stays that way. It doesn't reach the login screen.
I have tried a parameter restart, but to no avail. I have tried to boot from the original CD, but it goes straight to a kernel panic.
I have tried the hardware test from the original CD, but it says the hardware is OK. I have tried the Lion Restore disk (via startupdisk option, which works), but it also end in a blank white screen.
I have tried safeboot and it's the only way I have managed to get it started. The screen however seems low res or distorted by a wavy pattern. Almost like running in 256 color mode. When I managed to get it started I ran a permissions repair from Disk Utility, but there was no errors.
When rebooting it ends in a whiteout again.
Not quite the answer I was hoping for, but you are probably right.Thanks!
