iMac 27" Mid-2010 2.93GHz i7
While using the iMac, it suddenly shut down. No warning. Just black screen, possibly powered down.
Upon restart, it chimes, and 3 seconds later, chimes again. That repeats until I shutdown the iMac either by pressing and holding the on/off button or I unplug the iMac.
Restarted with nothing attached to the iMac. No change.
Restarted with various key combinations pressed (safe boot, recovery mode etc) on a wired Apple keyboard. No change.
