Hello All, hope this finds everyone well in these trying times. Well, my 2007 mac running high sierra just went I think!! It's been great right up till now, then yesterday while using it, it just blanked out to white, tried to reload the page and it didn't work, when we restarted it we got no chime and then the white screen with the question mark. I noticed that somehow the external hd was disconnected so plugged it back in but not sure that would be the problem anyway. Now upon opening there is no chime at all, and the white screen returns, question mark folder too. I searched on the internet for suggestions, but none seemed to work, probably because they all said "at the chime" do this" and I have no chime. Can't get into it to look of course. No keyboard no mouse just blank. I know it's probably reached the end of it's life but just wanted to make sure as this is the machine that my autistic child uses for his entertainment, educational apps, Youtube etc, nothing serious. It's just I want to make sure it's really gone before I think about replacing it, they are pricey. One more thing, if its dead how does one scrub it if you can't get into it? Thanks everyone Donna
