Hi, forgive my ignorance here! Although I've had my emac for five years now, since I had no problems with it and it did everything I needed it to (i.e. getting me through a graphic design degree and running indesign, photoshop and flash simultaneously) I've had no problems with it and therefore don't have a clue about its specifications! Before Christmas, as I was working on it, it suddenly froze and made a strange repeated beeping noise. I turned off the power and waited for a bit, turned it back on and expected everything to be okay. But nothing happened. The power light came on, but the screen stayed black and no noise to say it was loading up. Anyone hazard a guess as to what's happening? Tried it on a different plug socket but nothing again. Would be extremely grateful for any insights or advice.
