Ok I have had my 2011 Mac mini for a couple weeks now and it has been rock solid. It is the i5 2.5GHz version with the Radeon HD 6630m. I have 8GB RAM and a Samsung 256GB SSD. All of a sudden a week ago I went to start it (I shut it down every night) and it was on the Apple screen with the progress bar filling and it went black and rebooted (that was the second BONG). It got to the say screen and started progress and rebooted again (third BONG) and this time it booted up to desktop. It does this every single cold boot now. What can I do?
