Question : Identify an improper server shutdown

okay,
I live in a country where grid is not stable and we have very frequent power outages (at least twice daily).
I have installed a software on my servers (sbs 2008 premium, two physical machines) a small software that came with the ups that is supposed to shut down automatically the systems after a while.
when I restart the system, quite often I have some services which are not up. I suspect this is because the ups software is not doing its job. how can i check from the server logs if the system was properly shut down or not ? i tried to look in event viewer, but donno what the entry should look like.
