iMac won't boot - freeze at Apple logo - graphic card dead?
iMac EMC No.: 2134
Model No.: A1225
Hey guys,
since a few days my iMac won't boot anymore. After pressing the on button it is showing the apple logo and then the loading circle.
I am able to access the screen where I can select the different boot options or the bootable stick I have on via usb. But it does not matter which option I choose, it starts to load, showing the loading circle or a process bar (when trying to boot from UsB) but it freezes after a few minutes.
I also tried to access the BIOS like screen where it shows the booting process, but I wasn't able to read the problem from it.
I then brought the iMac to a local store to check it - they said that the graphic card would be dead and there were no replacement parts available. But I still wonder if this is right because the graphic card seems to be alright as the iMac is showing perfect screen and colours when accessing the hard-dive-choosing screen.
Do you have any advice how I can find out what's wrong with my iMac?
Thank you already in advance.
Best
Marvin
