Step #1 - Look in the message log (/var/log/messages), and ideally a copy 
of the console output, to see why you server stopped running. (or if your 
server stopped running)

The latter is important because your server can seem to be "down" when the 
problem is actually you cannot connect to it (the network is down).

If you can log into your server and get a shell prompt, then I would try 
the command uptime(1) first, to see how long the server thinks its been 
running, and then start looking at /var/log/messages for reboot messages, 
and /var/crash for kernel coredumps (if you panic, and have savecore set, 
it will create a core file there)
