I'll look into this.  Time to tear the old box apart again.

Thank you again.

The thing is, you are only masking symptoms.  There may be something
wrong, and perhaps you could save a lot of work later by fixing a
problem before it turns catastrophic.

from http://en.wikipedia.org/wiki/Machine_Check_Exception

A Machine Check Exception, also called MCE, is a computer hardware
error which occurs when a computer's central processing unit detects an
unrecoverable hardware problem.

Normal causes for MCE errors are overheating and/or incorrect hardware
installation. Overheating can cause electrons to become more animated
and thus escape from the silicon tracks, resulting in corrupted data.
Some specific manually induced causes could be:

Overclocking (naturally increases heat output)

Poorly fitted heatsink/computer fans (the same problem can happen with
excessive dust in the CPU fan)

Computer software can also cause errors in this way (normally by
corrupting data they are reading or writing). For example:

-Software performing read or write operations to non-existent memory
regions which leads to confusion for the processor and/or the system
bus.

3rd party programs

mcelog
    mcelog is a Linux program to decode MCE's on x86-64 processors
