It probably is a card issue then. The 5200 isn't qualified for Maya 7. It may work, but you will run into issues with Maya. Here is a list of qualified cards:

From that list, here is the explanation:

"Nvidia GeForce (ANY GeForce) Not Qualified Not Qualified"

"Nvidia GeForce256, GeForce2, GeForce3, GeForce4 series -
There are many cards based on GeForce256, GeForce2, GeForce3 and GeForce4 chipsets. Nvidia and Alias do not recommend these cards for use with Maya as you may experience various refresh, display and stability problems and inadequate performance. We suggest you choose from Nvidia's workstation cards instead, such as the Quadro families which are much better suited to high-end 3D packages such as Maya."

So, you can try and continue using the card, but I'm sure little problems will pop up now and again.
