Everything was working fine on the Mac until about an hour ago when I tried to install software updates and then the screen fades and a message pops up saying the computer needs to be restarted by holding down the power button.

After doing that, the computer is now stuck on a blank white screen every time it is restarted. FYI, there is no external hard drive connected to the computer. Here's what I have tried thus far to troubleshoot:

Completely disconnect from the electrical outlet and restart.
Restart with the OSX Install disc in (also tried this holding down "c", both times just goes straight to white screen and won't do anything else)
Tried resetting PRAM (it made the second chime but still wont go past the white screen)
Restart in single-user mode and safe mode (still just stuck on the white screen)
Tried restarting with any USB cables disconnected
Tried restarting with the Ethernet cord disconnected while holding down the D key per the instructions in the "Everything Mac" book (only thing connected was the keyboard + mouse)

NONE of this has worked or caused any different result, it's still just showing a blank white screen.

Can anyone suggest another possible solution or cause for this problem?

Thanks!

iMac (intel), Mac OS X (10.5.8)

    1. Logic board failure.
    2. Hard disk failure.
    3. Memory failure.

    These are all things that would need to be replaced and can't just be "fixed", right?
    Any idea why this would just all of a sudden happen? The computer has never presented any problems before, and it's less than 2 years old.

    I'm currently going the exact same issues at this moment in time. I guess I will have to take it the nearest apple store (2 hours away). This all occurred when I attempted to download new updates as well. Sounds like Apples fault since this is the 5th posting about the same things..

    I've got the same thing out of nowhere. Opened up my MB on Sunday (23/08/09) and got the blank white screen and nothing else.
    I can't remember precisely if the last thing I did on Saturday was install new updates, but I remember there being some last week.
    Looks like I'll be off to my local Apple store tomorrow.

    Actually mine turned out to be a HD failure. I couldn't get a quick appointment at an Apple store, so being a bit tech savvy I pulled the drive and tried to read it using a USB dock. Nothing. Not even the size was registering, so I guessed it was dead, bought a new one, and everything was OK (installed OS X, restored from TimeMachine, just like new).

    It seems strange to me I got no warnings about imminent HD failure, like from S.M.A.R.T. monitoring. Is this not used in OS X?

    My iMac is brand new, barely 2 months old. I've been getting the white screen quite often at startup. The only way I can get past it is to hold down power and reboot. One thing I've noticed... I'm pretty sure it only happens when I have external drives connected. If I shut down with my hard drives mounted and restart, I tend to get a white screen. If I disconnect them, startup is perfectly fine. I'd hate to have to disconnect Time Machine every time I power down, though. What a pain. Just installed Snow Leopard; perhaps it will fix this (though it did not, sadly, fix the missing "new mail" sound, so who knows)?
