Hi, the sound driver will probably be the intel one.
the network will be forcedeth or realtek
and the graphics...
The 73 is for pre-GeForce cards.
The 96 is for GeForce 2/3/4 mx cards
The 173 driver is for GeForce FX based cards...5xxx
The 177 is for GFX 6 and higher. (this one should cover the 7050,
but I found little reference to it, ie
GeForce 7050 PV / NVIDIA nForce 630a 0x053A
GeForce 7050 PV / NVIDIA nForce 630a 0x053B
GeForce 7050 / NVIDIA nForce 610i 0x07E3
