    iMac stuck at grey screen after logo scn

    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...

    Mac suddenly froze now I can't use it

    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.

    How to get Firmware Restoration CD to work?

    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...

    How to get Firmware Restoration CD to work?

    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...

    How to get Firmware Restoration CD to work?

    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...

    How to get Firmware Restoration CD to work?

    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...

    Help - cannot install OS X on new hard drive.

    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...

    Help - cannot install OS X on new hard drive.

    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...

    Help - cannot install OS X on new hard drive.

    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...

    Help - cannot install OS X on new hard drive.

    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...

    Help - cannot install OS X on new hard drive.

    Checked memory again and it is well seated and also tried several other memory cards that all pass the hardware checks but still the iMac wont load the install disk and hangs at the same point. Is there anyway I can check the video card with a utility program that does NOT require OSX on the...

    Help - cannot install OS X on new hard drive.

    OK, so what I think I have concluded is that the iMac crashes when it attempts to run the Graphical User Interface (GUI). I'm thinking this is the order in which I should try replacing things. 1) Graphic Card - nVidia 7300GT 2) Motherboard 3) Power Supply 4) Memory 5) The Whole Lot! Are there...

    Help - cannot install OS X on new hard drive.

    It was the full retail version bought from Apple, it has the Snow Leopard picture on it so it's not the grey version that comes with the mac. I have the grey disks that came with the mac but both these and the retail version seem to stop installing while the apple logo is on the screen.

    Help - cannot install OS X on new hard drive.

    Hard driver is properly seated, trying to work out if I can access it in Single user mode to confirm it working. It does sound like it spins up and it works ok in my external housing. Not sure if there is a problem with graphic card, it seems that the iMac freezes just when install is about to...
