RPC error causes shutdown

i randomly get an error that states an RPC process has been terminated and a countdown to 0 that causes my machine to reset. it does not seem to happen off of any key event or having a certain program running. ive ran norton antivirus but the error comes up before antivirus can finish scanning my drive. has anyone had a similar problem or can give me any advise? ive checked for programs that are running on startup as well and none of the ones that start up would cause this error.
