Your motherboard has an Intel 865G Chipset
, which includes an Intel Extreme Graphics 2 IGP
The Extreme Graphics 2 IGP only Supports DX7 in Hardware
, with some further DX9 features being software emulated.
The Windows 7 Aero interface Requires
hardware DX9 including pixel shader 2.0 support and a WDDM Driver
As your IGP has no DX9 support, and only a XPDM Driver
is offered, there are, and never will be, Windows 7 drivers for your motherboard.
