Not out of the woods yet, computer-wise

I turned my computer on this morning and that little whirly thing that Macs do on start-up wouldn't stop whirling.  That's not a good sign.

It could be that I'm without a computer for a while after John heads to work.  Crap.  

On the upside, I have a doctor's appointment this afternoon so maybe I'll make some head-way in getting further tests books or finding some answers.
