Ron:
I would guess it's probably too late to do so, but is there any way you
could cancel that $69.95 order for the "BIOS upgrade"? In all candor, I
really think your best bet at this point is to bring your computer in to a
local computer repair shop. Assuming there are no defective hardware
implications, I'm reasonably certain that they could return your computer to
a functional state at a reasonable cost. At least they could give you an
estimate of charges and you could then make a decision as to whether you
want to go that route.
