Hey Dave,

Obviously, each component that you transfered from the old to the new 
system is suspect. Drives usually fail miserably, not after a while... 
though, it's not impossible to suffer a long death. But, when they do, 
it's usually noticeable upon reboot... but, again, not always (not an 
exact science!). It's possible that you have a bad area on one of the 
drives that is used for the swap space and when a critical area is 
swapped it bombs.

 From the thermal pov: Did you bring over IDE or SCSI cards for your 
drive? If so, you might swap those out. But, it's stretching.

It sure sounds like a memory problem. (note that not all memtests test 
memory effectively).  Sometimes a memory problem is so small that it 
doesn't necessarily effect the operation of the computer until later at 
a random time. If I were you I'd swap out all memory and let it run.
If you can't swap out the memory, you could try booting up into DOS or 
BIOS and just let it sit there for a good long while. Just something 
that wouldn't exercise RAM to eliminate thermal or other parts that 
you've transfered from the old computer.
