The other night I updated my iTunes to the latest version (through Software Update) when I came to turn on my computer I was greeted with the dreaded white screen of death.

I use an early 2008 iMac 24".

I've tried the basic things, unplugging/turning off accessories, trying to boot from the install disk, reseting pram, etc, etc.

Still no luck and no change what-so-ever.

All I've been able to ascertain that my keyboard still works (by ejecting).

I should point out that I did recently replace my Hard drive with a Western Digital Black 500GB (though the computer is well out of warrenty) and I'm a little concerned that the problem could be the screen.

Update (18/05/10): I've been told that I could be getting the White/Grey screen of death because the optical flex cable is damaged (aparently this is common). Apparently the Optical Drive is part of the POST sequence, and an inability to read the drive can result in failure for the system to move on to other bootable volumes. More info here. I will disable the optical drive and see if that works.

Well, if you think it's the screen, how about plugging in an external CRT or projector and seeing if that works? That'll tell you for sure... –  marcusw Apr 30 '10 at 16:33
    
I'm a little concerned that the problem could be the screen -- then what is the white screen of death you're referring to? Apparently not a Kernel panic screen? –  Arjan Apr 30 '10 at 16:35
    
No, I didn't get a Kernal Panic. Everything was working fine before I shut the iMac down. –  cust0s Apr 30 '10 at 16:52
    
If only so simple! Unfortunatley I'm not in a position to do that at the moment. –  cust0s Apr 30 '10 at 16:53
    
Ah, my reference to the kernel panic was wrong; I thought a white screen of death was always supposed to show something, but apparently not. Still: is it really just a white screen, or is there some indication on it, like Gray screen appears during startup? –  Arjan Apr 30 '10 at 17:37

I had a similar problem on my MBP13 late 2009. What I did was booting from a bootable backup that I had on a external USB harddrive. Then I could change the primary boot device to my DVD-drive and reinstall Leopard (and start the upgrade process to Lion yay!).

Note: you should use the install discs that came with your mac, not any upgrade discs.

You cloud also try booting from the install disc, I know you said that it didn't work but please try. I had to wait for 5 minutes once.
