Thank everyone for their input!!
I have verified the disk. I have run ONYX and SMART Utility with no errors found. And now, I have run Apple Hardware Test in Loop Mode overnight (8 hrs), also with no errors.
I read in the Apple hardware Test instructions (the ones that come on the DVD) that "In many cases a clean installation of the MAc OS X fixes recurring problems." Any thoughts or advice would be appreciated greatly!
