iMac 27 - Using High Sierra.
As soon as I switch on, a black screen with blue lines appears. Nothing loads past this point. I've tried restarting in safe mode, or with Option/Command/P/R keys down, so far nothing helps. Any help appreciated.
iMac, macOS High Sierra (10.13.1)
The GPU is failing, take it to an Apple Authorized Service Provider to be professionally diagnosed and if you choose to, repaired.
