Hi all,
Hope you can help. I've got an iMac (27" Mid 2011) running Sierra. A week ago, i turned it on and was welcomed by the apple logo then half way through i got a grey screen which darkened slightly and just stayed like that. I tried everything to the best of my knowledge..
The apple logo appears but then it flashes for a second to the grey screen.
Any ideas what this could be? I cant get into the recovery partition nor internet recovery. I've also tried to put another HDD in with sierra installed but same problem.
Thank you.

- PRAM Reset,
- SMC Reset
- Single user mode to check the disk with fsck -fy
- Diagnostic shows nothing in basic and extended tests
- Reinstalled Sierra
