Removable Motherboard Tray Is My Video Card Removable Or Part Of Motherboard?

Is my video card removable or part of motherboard? - removable motherboard tray

I have a Samsung X15 laptop with a 5200 + video card 64 MB NVIDIA GeForce FX Go

The laptop LCD screen has vertical lines, which showed that when using a CRT monitor.

I think it's because there is a problem (with the video card that right), but I replace them? If it is indeed positive, I could identfy where the problem is?

Thank you in advance.
