Can your nvidia geforce support to grand theft auto4

If you have to ask, then no. GTA4 has very high system requirements and will generally only run a system built for gaming.

Nvidia Geforce only represents that it is a graphics card made by Nvidia intended for non-workstation use. It should be followed by the actual product name such as 8600GTS, 9800GT, or GTX285.

Unless you did purchase this card on your own and install it (in which case I'd assume you'd know the model) or bought a gaming computer costing over $1,500 then I doubt you will be able to play it
