I have an Intel IMAC, which is now out of warranty as I have had it for 16 months (and I was dumb enough not to get AppleCare). A few days back, my computer would not startup and everytime I hit the power button, I would hear some spinning noise but no chime from the iMAC. Yesterday, I tried it again and this time I heard the chime but the monitor did not start. I was then able to SSH into the MAC and see that it is indeed connected to the network and booted up, but the screen is still dead. Any ideas what I should do before the painful trip to the apple store ?
