I don't see any VGA drivers listed for any of the Windows 7 versions,http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Desktop+Boards&ProductLine=Intel%C2%AE+945+Express+Chipset+Family+Boards&ProductProduct=Intel%C2%AE+Desktop+Board+D945GCCR
Guess they felt the drivers in the O/S (Win7) would support the Intel 945GC chipset, and it's Integrated Graphics. (Intel GMA 950)

Intel 945GC chipset info,http://en.wikipedia.org/wiki/List_of_intel_chipsets#Core_2_chipsets
IMHO the next course of action to take, would be to buy an economical PCI Express graphics card, and install it in the
PCI Express x16 expansion slot, on the motherboard.
It will have drivers for Win7.
[Driver: A small piece of software that allows the Operating System to communicate with a device.
Win7 is the O/S, and graphics chipset is the device ]
Something as economical as this example, will work,http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2759376&CatId=3585
The Intel 945GC came out in the first quarter of 2007.
According to what I read, the launch date was the first quarter of 2005.
Don't know what transpired in the meantime. Maybe Intel didn't release it until it had PCI Express 2.0 support.
At any rate..........
PCI Express is a technology.
The first release under the PCI Express name, was the
PCI Express 1.0 version.
Next upgrade version was PCI Express 1.1
The version after that was PCI Express 2.0
Year? 2007 (January 15, 2007)
I don't know if the 945GC chipset on your motherboard, uses the
PCI Express 1.1 version, or the PCI Express 2.0 version.
The graphics card is based on the PCI Express 2.0 version.
Does it matter? NO
Because PCI Express 2.0 is Backward Compatible, with
PCI Express 1.1
In otherwords the PCI Express 2.0 graphics card WILL work, on a motherboard based on the PCI Express 1.1 technology.
Will you get the full capabilities of the PCI Express 2.0 graphics card?
Will you notice?
PCI Express 1.1 technology has a PER lane data rate of 250MegaBytes per Second. (250MB/s)
A transfer rate of 2.5GigaTransfer/s per Second. (250GT/s)
PCI Express 2.0 technology has a per lane data rate of 500MB/s.
A transfer rate of 5.0GT/s ]
