Hi Dan

What version kernel, nvidia driver and filesystem are you
running?

I updated my nvidia drivers to the latest 2313, and only had
problems (screen corruption, lockups, etc) on a system that
had been running stable for a long time now. i went back to
the previous version, and it is 100% again.  I also had problems with my
old savage and sertain drivers.

Then, nearly a year back, I had the same type of problems
(lockups), but this was due to bad ram, and a kernel/reiserfs
and hardware compat problem.
