Hello Thomas:

According to a recent post by Glenn McCorkle, a computer is supposed to
be able to operate from temperatures as low as 20 F. and as high as
120 F.  ( If my memory is serving me well, I believe those are the figures
he mentioned. )

My computer is an Acer 386sx., ca. 1990.  It has no CPU fan, but it does
have a fan to blow hot air out of the case and to suck cooler air back
inside the case.  If running, it will crash if the ambient temperature falls
to around 35 F.  If turned off, it cannot be made to boot again unless the
ambient temperature is approx. in the range of > 65 F. and < 85 F.  If left
running, it will continue to operate even if ambient temperatures should
rise to the 90's.  Also, if turned off for a long period, it won't boot for
at least 15 minutes after being turned on.  The hard drive always spins up
immediately.  I think it is about time to replace the motherboard.  My
computer didn't used to suffer from any temperature-related quirks a couple
of years ago.
