Hi unfortunately the link is incomplete . Have you tried the steps as suggested? Also what you can try is to remove the memory modules from the system and then try with one module at  a time. instructions can be found on support.euro.dell.com--enter tag #--submit--manuals.

I'm sorry.

Thank you for the link. Looking at the symptoms it could be a hardware issue or could be a loose connection. Have you tried the steps as suggested. Also please try an external monitor if possible and let us know if you get a display. await your response.
