Random lock up

I'm using WindowsXP SP2 with all pertinent patches applied (except SP3, of
course).

Over the last two weeks my computer has started randomly locking up. The
symptoms include:
1. Upon returning to the computer after an extended period of time, all I
see is the desktop background image. The mouse works, but there are no
icons, and keyboard shortcuts (Windows key, ctrl-alt-delete, etc) have no
effect.

2. Occasionally, while working, the system will freeze. The mouse still
works but will not activate or allow me to interact with any of the visible
windows. Ctrl-alt-delete will bring up the usual dialog, but pressing any
button results in full lockup other than the mouse.

I have run a full virus scan (Eset Nod32) and spyware scan (Counterspy),
with nothing found. I also ran the full suite of Dell diagnostics from the
command line with no hardware problems detected.

I have recreated the page file in case it was corrupted. I have also run
sigverif, but came back with 33 out of 331 unsigned files in
system32\drivers. I haven't directly updated any drivers in quite a long
time, so I'm questioning whether these unsigned drivers are significant to
my problem.

Any other suggestions as to further troubleshooting?

thanks,

Bob M..
