iMac won't turn on unless I remove and reconnect power cord

About a week ago, my iMac stopped turning on with the power button.

Now, if I shut down, I can only turn the iMac on if I first unplug the power cord from the back of the Mac and then plug it back in. Then the power button works fine.

Has anyone encountered this issue? Sounds like an OS or firmware issue to me.

iMac 2.16 GHz Intel Core 2 Duo, Mac OS X (10.5.1), 3 GB RAM
