I had a problem a few years ago that manifested itself in a very similar
way: all of a sudden X would lock up, then I could not kill X, even
with signal 9 from root, and then very spooky behavior of all sorts.
Eventually I determined that, despite first appearances, the problem was
not X in particular, but any CPU-intensive task. So I opened up the
box, and lo and behold the CPU fan had died (this was a
very-slightly-overclocked Cyrix, and so very susceptible to
overheating).
To rule out the sort of problem I had, you could try stressing the box
in console mode by compiling the kernel -- if the same thing happens as
with X, and/or Signal 11's, kernal panics and such, then you have a
hardware (overheating, bad memory, etc.) problem.
