Database Restore caused production server reboot

I got a production server with the following hard ware software
Server: Dell PowerEdge 2950
Storage: FS SAN 650
Memory: 4GB
windows 2003 standard (sp1)
sql server 2005 standard (9.00.2153)
There are five user databases, their size range varies from 12GB to 15 GB
I wanted archived data from one of the databases, so started database
restore process from old backups that made server to freeze then rebooted it
automatically. I found the following messages in the event log. My question
is how a restore process will bring server shutdown. With the same memory
and i had 150 databases in dev environment and never got a server reboot
with database restore. Can you please let me know your expert ideas what
else might have caused the reboot if not the restore process.

The server was unable to load the SSL provider library needed to log in; the
connection has been closed. SSL is used to encrypt either the login sequence
or all communications, depending on how the administrator has configured the
server. See Books Online for information on this error message: 0x2746.
