thanks.  i do have one of those PSU testers, but it isn't Antec brand.
i will test it out.

the system froze up again, so i removed the proprietary video drivers
and put back in the free drivers.

i ran memtest for a few hours and let it go through a whole pass, there
we no errors.

i've got 'watch -n 10 free' running in a screen so we'll see what that
shows next time the system freezes.

i've looked into stresslinux livecd but that isn't feasible right now
since this is our security camera recording station and it needs to be
running as much as possible.  i will try out the 'stress' package,
though, and see if the system freezes under a high load.
