Normally, long protracted shutdowns are caused by applications
that are writing to disk, or are supposed to and are not responding.
Have you scanned the computer for spyware? Maybe you got hit
by a site you visited on the 30th.
According to what you say, it reboots on the average about once a day.
Any particular time, or anything you are doing? Sometimes a virus
will need a reboot to replicate itself. Maybe a .pdf file? Seem to
remember a worm about the time frame indicated?
I use pc-cillen. They have a free online scanning tool. at
http://www.trendmicro.com/ Why not scan the computer
and see if anything comes back on it.
Last thing may be some scheduled task that is rebooting the machine.
Check the logs for anything scheduled and see if it may be
initiating the restart.
