WARNING!
Did your computer just act as if it was struck by lightning?
Please, check the following!
1) Has a heavy truck crashed into the building your inside? If not, continue to paragraph 2!
2) Use the following link to control if an earthquake has occurred at your location: http://wwwneic.cr.usgs.gov/neis/bulletin/bulletin.html. If not, continue to paragraph 3!
3) If the suggested explanations above has been excluded the most probable cause is that your computer is running a Windows operating system and you're browsing these pages with Internet Explorer. To avoid such effects in the future you should consider the use of another operating system and/or web browser. If you are running an older version of Windows (for example Windows 98) another alternative solution is found here.
