iMac shuts down after welcome Intro
When i press the power button i see the apple logo, then it loads the mouse on the upper left side of the screen.
After that i see the welcome screen intro, after that intro the screen becomes black, not sure if turns off or not. i don't hear any sound or something running.
I tried to boot from usb it was stuck at the grey boot screen with the apple logo
what could be the problem?
P.S i'm thinking about turning the imac to a screen with an lcd controller if couldn't find a solution.
