Just a hunch, but did you turn the monitor back on?
Another way is to try to connect it to another pc or laptop and see if it works.
Yes, of course!
I have tried it on my old pc, same problem.
One thing I forgot to mention. Before it stopped altogether, thats before I moved it. When booting up, the monitor took an age to come on, green light still blinking, even though the harddrive had done its paces. I am talking about 15 mins or so. Any clues?
