It does look like it's a problem with the PSU or (God forbid) the cpu. ("God
forbid" because new CPU means new motherboard also).


So, I would say that you have shown that your memory chips are not

Well at the moment it doesn't even survive the early stages of a short
compile (the ./configure stage) so hopefully if any progress at all is made
at diagnosing the problem, it'll be quick. Unfortunately if I were paying
you to diagnose the problem I'd also have enough money to buy spare PSU's -
but I'm not!
