Are you using xlockmore or another package to lock your screen, or display
a screensaver. I've had issues with opengl-based screen savers (xlock)
locking my X display when they've run for a long time.
I've also had issues with firefox hogging tons of memory (very
memory-leakish). If your using it you should keep an eye on its memory
useage.

it may only be X freezing up on you. sometimes ctrl+alt+f1 or
ctrl+alt+bckspc works to get out of a frozen X session.
maybe some process on the box has found a way to use all userspace
processing cycles. icmp packets are handled at a very low level in the
OS... so often when a system isn't responsive and can't even be
connected to with ssh, it will still respond to pings. that's a good
test.
keyboard events, I think, are also handled at a very low level but if X
is frozen then you won't see any echo. need a console for that.
are you getting any messages in the logs that might give a clue?
sometimes you'll see a kernel oops. when my laptop crashes because of
my windows nic driver I see in the logs messages about about packets
that are too large. or disk read errors/timeouts... stuff like that.
I hear compiling a kernel is a good way to test memory. if your
compiler segfaults (sig11), you probably have a bad stick. I've heard
this can be more reliable then memtest programs.
