I wonder if anyone can help me (or has experienced this issue)
My iMac only started doing this recently, where at random times the screen would go blank and be unresponsive, forcing a hard restart, other times if would come back on after a few quick presses of the power button.
Other times the blank screen would come on prior (and just after the chime sound)
Anybody know what it could be ?
I have El Capitan (potential cause)?
I have tried resetting the PRAM and reinstalling El Capitan. (Have not tried Windows or downgrading to Yosemite yet)
