How can i find out what crashed my Windows Server 2008 R2 box?

My file server just went belly up and I can't seem to figure out why.
Perhaps I'm naive but when these things happen I can typically look
through my System, Application or Security Event Viewer log and find the
culprit - but no luck this time.
While I was out of the office I received an Icinga notification stating
that the E:\ drive on my server was warning that it no information was
available for that drive.
I logged onto the server to see the E:\ drive was there, but there was no
"storage graph" located under it like there normally is, and clicking on
it hung the OS. I then tried to reboot the server and the hanging
continued. I issued a stop-computer server -Force command, which seemed
like it was starting to work however the screen hung stating "Please wait
for the System Event Notification Service". I had to do a hard shutdown on
the server, which is never a good thing.
My question is if there are no diagnostics in the event viewer, is there
anywhere I can go post-incident that can show me what caused the crash?
I've never had a server lock up on me in the fashion this one did so I'd
like to know what the root problem was.
