Error Code 2000-0334 - Remove & reinstall Video Crd/Graphics Card

Hi,

This morning my XPS M1330 laptop has developed two purple lines 2 inches apart down the left hand side of my laptop.  I did a self test and came up with Error Code 2000-0334.  When I went in to Dell Support for error codes I got a Click to Fix link which advised that I should Remove and Reinstall the Video Card/Graphics Card and gave me a link to the Service Manual.  I have searched this manual inside out and am unable to find anything to do with Video Cards or Graphics Cards. 

Can somebody please tell me where I can find service manual information re removing and reinstalling Video Cards or Graphics Cards.

Or alternatively can you please give me any other information on how to fix this problem.

Exasperated Too
