Why is my screen black but fan and HD are running
My iMac was working but after shutting down and starting later the screen just stays black but the machine is running. have tried numerous options. pram reset, remove power, etc. but no success????
Is this a good question?
How long have you let the iMac run? It’s possible it’s hung running an update.

Not the case as I shut the system down and only when I came to restart it did the problem make it self known.

@gavin89727 It’s less likely, but still not impossible that an update would process when you shutdown. It could have been pending for some time. Otherwise, I would see if you can connect it to an external monitor since it sounds like this may be an issue with your display.
