Hi,
Had a very similar problem when my mac stopped booting at grey screen and spinning wheel stopped.
After the initial boot the mac will try and switch the graphic card to graphics mode. If the graphics card is damaged then the mac will lock on the grey screen. Got a new graphics card and...
Try using Warrior 4 or Dara Rescue 3, sounds like your hard drive has become corrupt. It may still be repairable but,would suggest you back up everything before doing much else.
Is this a video card problem?
I have hooked up an external monitor and disconnected the internal screen, this seems to set the primary monitor to the external screen. I have managed to install windows xp using the external monitor, if I reconnect the main screen it just goes blank during boot...
Just a quick update:
I have plugged in an external monitor and successfully installed windows xp and used xp installer to partition the drive.
I cannot see anything on the main monitor yet it only works the external monitor.
Going to try a few more things to see if I can work out what the hell...
I have tried booting up from an external USB DVD drive and still the same results with the internal DVD disconnected.
I'm going to buy another video card before I finally give up, I'm not very hopeful that this will work as there doesn't seem anything wrong with the video card other than I just...
I have tried using an external DVD drive, also I created an image on a USB stick and USB hard drive using TransMac on a PC. I didn't disconnect the internal DVD drive but used the option key to ensure I booted from the external USB source.
All did exactly the same and only booted to the Apple...
Yes done that, I think I have done just about everything now and only left with the possibility that the logic (motherboard) is faulty. The Apple Hardware Test says everything is fine both on standard and extended tests, I have even tried booting a windows xp disk to see what happens but the...
I can't choose a hard drive to install to, the installer hangs on the grey Apple screen.
All common issues have been checked:-
Original disks correct and alternative disks tried.
External DVD tested and still the same.
PRam and NVRam reset.
Booted up using option key and selected OSX...
I suspect or at least would like to rule out the possibility that a corrupt firmware is stopping my iMac from reinstalling.
I have downloaded the Firmware Restoration CD image from apple, version 1.4 and burnt it to a CD using a PC with TransMac.
I have held the power button down and get a...

Thanks again for the suggestions.
I have now tried an external DVD drive and the same happens, I have also created an image from the install disk on to an external hard drive and still the same.
Is it possible the firmware is corrupt, or does this get restored when you do a fresh install?
I...
Yes I have used the hardware test program that came on the original grey disk 1 by holding down D on boot up.
The Hardware Program says No Problems Found, it think it only checks memory and the logic board. It will list other devices such as the video card but it does not seem to check it.
If...
Yes this is what I used to check the memory, original grey disk 1 and holding down d on boot up.
This only checks the main logic board and memory, it gives a list of other devices including the graphics card ( nVidia 7300GT) but does not test it.
Do you think the video card is ok if I can...
