A thin client right, not an installed desktop?

Sounds like the thin client crashing then.  If you can figure out how, you
could set up a network syslogd on the server and get the thin clients to
send logging information across the network.  This _might_ give you a clue
why it's crashing.

The only other question is the environment.  If it gets very hot in that
corner for some reason, it might cause a crash.  You could try and figure
out how hot the machine is.

You seem to be describing a situation where the location is the problem.
If you replaced all of the things you said, then there is a completely
different computer in place and you still see the problem -- only the desk
and the sockets are still present.  If you can confirm that that computer
works fine elsewhere, I can't see how it can be a software issue.

This assumes the problem computer is doing all the same things as the
others -- ie you don't happen to do something unusual with that computer
that you don't with others.

It seems unlikely to help alright.
