Windows 7 - Event 18 WHEA-Logger Error in Event Viewer

I've seen this error (Event 18 WHEA-Logger Error) message everyday(lately) in the event viewer. What concerns me is in the message, A fatal hardware error has occurred.

Any insight to this error? I've attached a copy of the event viewer error.

Is this anything I should be concerned over?

I appreciate any feedback or suggestions.

Thanks,
Greg
