This reboot problem just poped up but a few months ago I had a power supply go
bad.  It was built into the case and I had to buy a new case and power supply. 
So it is likely that there is a loose connection after I moved the mother board
to the new case.

I will also check the memory as Colin suggested.

Thanks for the suggestions.
