yes, I have owned units like this, where the fan would kick in to cool the 
machine down, but in this case the fan was turning, but stopped 
entirely..will answer the rest below.

The button was functional previously, with the case not having been opened 
for  a few months now.

Great question!
I have never owned a computer with
1. a case that is so hot to the touch that I can smell  slight  smoke 
sometimes, and the smell I associate with heat.
2. where  my computer clock jumps in time  rapidly..fortunately that only 
happened once.
3.  My speech source is an internal card.  as the case, smell, heat 
increases, the speech  starts to increase on its own.
The case heat alone is Unusual for my experience.  even the metal around 
where the fan should be turning is quite warm to the touch.

Why?  the button was functioning long after the cables connecting the cd 
rom were left loose inside the case.

Perhaps, but the slight smell of burning suggests heat inside the case, 
and I have never owned a machine that ran this hot to the touch.
