Hi,
This is a duplicate of a thread I posted over on the MacFormat forum. I wouldn't normally do that, but I can't stand being offline for long and might do something rash like buy a Windows 7 laptop or something...
Anyway, basically my iMac is dead. I'm tempted to try and dig out the hard drive, but though I might see if anyone recognised the symtoms before doing anything too extreme. Basically my iMac had a kernel panic, I shut it down and now when I try to start it up, it gives the startup "bong" (sorry to be so technical) and then I'm just left looking at a light blue/grey screen. Nothing else happens.
It is a 20" iMac, with 2GHz intel core2 duo processor, bought in Jan 2008. I was browsing some photos using the slide show viewer, when I noticed some glitches and one of the photos I wanted to look at didn't show. I went back to the finder to try and bring it up and next thing I know I'm looking at the kernel panic screen telling me to reboot.
Rebooting just left me at the blue/grey screen (not the deeper blue one just before you log in), so I pulled out all the peripherals and tried rebooting again - nothing. I've tried rebooting with the shift key and the D key - nothing. Oddly, rebooting with command, option, P & R does cause it to reboot again, but it still doesn't get any further.
I then tried reseating the memory chip because it's the only user accessible part. Predictably it didn't help.
I then popped in an old Knoppix live linux CD and tried to boot of that (tried holding C key) - still nothing and now I can't get the CD out. I've tried rebooting holding down the mouse button and rebooting holding the eject key.
Anyone know what's like to be causing this problem? All help gratefully received!
I'm posting this at work and don't have a working computer at home, so obviously I'm not going to be too responsive, but I will be watching
