Please help Server Error 500

Thank for the help ahead of time. Just tried loging on to my Drupal installation that I had working for over four months and now nothing. After loging in Internet Explorer showing Server error 500 Firefox showing nothing. I was able to get server logs if some one can take a look please and see where there might be a problem.
