In Need Of An Hp Compaq Nc 6000 Display Card

Please where and how can i get an HP Compaq NC 6000 Display Card?, or better called VGA Card. I have the Laptop, but the screen just goes off arbtrarily or any time I try to close the lid of the laptop or even when it is shaken. After I took it to one engineer, I was told that it was the display card that had the problem and I will have to change it for the laptop to be working normally.
Anyone  who has an info on getting it should please contact me through my e-mail; wilfem2002@yahoo.com
Thanks in advance

@ Miksoniks,
Thanks for your reply/response, I'm indeed glad, but the problem here is that I'm based in Abuja and I don't know how I can get it over there for it to be fixed. It also started to give me this 'Non system disk error' each time I try to boot it and as a result of this, it can't even boot, not to talk of managing it with the problem of the display card which makes it go off arbitrarily.
So what do we do now?
Awaiting your response.
