My iMac is freezing with three very loud beeps, more and more... at first, more than a year ago on 10.6.8 it did this infrequently... now, the last months with Lion 10.7.3 it is almost DAILY! Watch the three emergency beeps here:

Apple iMac Freezes - Loud Beeps Three Times - Emergency - YouTube

Any ideas how to solve this?

iMac a 21.5-inch, Mid 2010 model
Processor 3.6 GHz Intel Core i5
Memory 8 GB 1333 MHz DDR3
Graphics ATI Radeon HD 5670 512 MB
Software Mac OS X Lion 10.7.3 (11D50)

Happens with no applications running, or some, or when sleeping, just HAPPENS and it should not. Wi-fi dropping *is* a major problem as well. Thanks for any tips to solve these three beeps and the my freezing iMac!
