I ran acpi -V several times during a half hour period and received a 
'Thermal 1: ok, 40.0degrees C:'
each time .

As for component checks, I have several operating systems on this 
computer, Windows XP, two Debians, UBUNTU 7.01 CD & DVD versions, UBUNTU 
8.04 CD & DVD versions, some on an external HD.  They all work 
flawlessly except both 8.04s with their tendency to freeze.

You're probably wondering why so many operating systems.  Mostly, it's 
because after I try a system, I hate to remove it.  The 8.04s are a 
challenge.
