You'd think that would be the case, but I've seen some co-worker's
machines that had an obvious overheating problem that would shut down
and then immediately reboot. When they shut down they were
performing CPU-intensive functions. After shutdown/reboot the CPU
load was substantially less and the fan was able to cool the
processor sufficiently to keep the machine alive.

FWIW,

The SMART information is useless. Run a full scan of the hard drive
with Data Lifeguard Tools....their "long test" that includes checking
the drive surface.

Did you make a Data Lifeguard Tools bootable CD, or did you install a
Windows version of the program?
