System crashes for no apparent reason
I am running a reasonably up-to-date Squeeze box (it has been a few days
since I did an aptitude update and safe-upgrade). This problem has
actually been occurring sporadically for a few weeks now. The system
will simply die. I leave the computer on 24/7, normally without
problems for weeks, or months, but lately that has not been working.
A few weeks back I had hard disk failure. After I replaced that disk
and reinstalled Squeeze (and /home and /usr/local from the old disk)
several problems started occurring. The dying system is the most
annoying. I will wake up, or come home from work and find the monitor
showing it's "No Signal" screen and the box is totally unresponsive. I
can not ssh in, or anything. The system is completely down. This
happenned every couple of days for a while and then it seemed to go
away. For at week, or more, I had no trouble. Then, yesterday evening
it died. After verifying that I could not ssh in, I rebooted. This
evening, I came home from work and spent a few minutes at the computer,
then had to go out at about 6:20PM. When I came back the system was
dead, again. I rebooted. This time I went through syslog and copied
out the parts just before the system died each of the last two times. I
generally try to avoid having to look at logs, but... I have inserted
those sections of log below. The only similarity that I can find is
that, in each case the last thing that shows in the log was running
cron.hourly. The only problem is that there is nothing in
/etc/cron.hourly/ (it is an empty directory). There are some entries
concerning the nouveau graphiocs driver. I know nothiong about drivers,
but I'm sure someone out there does. Is it pointing to a problem?
Anyway, here are the log snippets:

If there is anything here that points to a problem, please let me know.
If there is any other data that would help diagnose this, I will do my
best to provide it.
Thank you for any help.
