If you're checking an eventid, I would use eventid.net [eventid.net].
From the info their it appears that the error could just as likely be entirely benign as to be a symptom of hardware problems. Job number one is to verify that your backups are up to date and working correctly. You do have backups don't you? ;)
Once you're confident you have backups I would work through any of the suggestions that seem to fit your situation.
