Hi, I have an iMac 27” 2.8Ghz Corei7, (Late 2009). This morning when I woke it from sleep it started emitting a continuous beep sound, it was still showing screen pages and images, but with a black background.
I was unable to control anything. so I pressed the button to shut it down and restarted it. When I restarted it all I had was a white screen and a continuous beeping sound. I again turned it off and did an SMC reset, unplugging the power cord and all the peripherals, turned it back on white screen and beeping. I did a PRAM reset, turned it back on and had the same result. (There was no grey screen and no start up sound). As I was searching the internet to see what more I could possibly do, I let it continue to beep in the background, after about 5 minutes, the beeping stopped and now I have a flashing grey folder with a white question mark inside it. Does anyone have any idea as to what else I may be able to do to fix the problem? Take care. Matt
