My wife's flat screen iMac won't start up. When you press the power button, the fan starts and it beeps three times. The power light on the screen flashes...one long flash, three short ones, then off for a few seconds then repeats.

It was working fine yesterday. She had updated to 10.4.11 the day before. The first time she restarted after the install, it stuck on the gray/apple screen, but when she restarted after that, it was fine. Then, late in the day yesterday, it just shut down all by itself. When she tried to restart it, it behaved as described above, and the same today. I've also tried disconnecting all peripherals and restarting...same thing.

Any advice would be welcome! It has a new logic board, as of a month ago.
