I'm thinking it's BIOS related.  I manually set the CPU speed in there
because it didnt list 2200Mhz.  Now I'm running it at 2000Mhz and
untar'ing pkgsrc didn't make the machine crash.  I remember when I
slightly overclocked the machine, it wouldnt even boot from the cd; it
would just hang.  After setting it back to 'automatic settings' for the
CPU, it worked.  I thought I could get away by manually setting the speed
to 2.2Ghz, but I guess that didn't work.

I'm going to try more stuff and see how long the machine stays up.

Thanks
