Doesn't matter if you have an Intel Pentium D processor.
What does matter is what Southbridge chip is on the motherboard. It handles the audio (Integrated Audio) of the motherboard.
If this motherboard is an Intel D945GCCR model, here is the driver download page from Intel Support,
Intel has an automatic update and detect drivers feature.
I would suggest using it.
(The digital signature has been verified, so click on RUN.
I would have clicked on RUN anyway. It is INTEL, sheesh!)
Would also like you to read Troubleshooting audio issues,

[ Southbridge Chip:
The Southbridge chip is part of the motherboard chipset.
The Northbridge chip, and the Southbridge chip.
{Does not apply to motherboards supporting Intel Core i3, i5, i7, and i9 processors. Different technology is used }
The Northbridge chip was so aptly named because if a motherboard were a map, the Northbridge chip would be setting to the 'North'.
{It's located immediately south of the Processor, under an aluminum heatsink}
The Northbridge handles the faster capabilities of the computer.
The Processor, Ram Memory, and High-speed graphics.
High-speed graphics being AGP, or PCI-Express.
A graphics card inserted into a white PCI slot, or Integrated Graphics on the motherboard, is Not high-speed graphics.
The Southbridge chip handles the slower capabilities of the computer.
Audio falls into this category.

http://en.wikipedia.org/wiki/Northbridge_%28computing%29The Intel D945GGCR motherboard uses a;
A) Intel 945GC Express chipset GMCH for the Northbridge chip.
(Intel 82945GC. There is an aluminum finned heatsink sitting on top of this chipset.
Looks like a meat tenderizer.
If it wasn't you would see Intel i945GC - 82945GC )
B) Intel 82801GB for the Southbridge chip.
(ICH7 - 82801GB. This part number you can see. No heatsink)
C) RealTek ALC883 audio

More information on the Intel 945GC chipset,
http://en.wikipedia.org/wiki/List_of_intel_chipsets#Core_2_chipsetsUnder the Chipset heading look down to 945GC, then read across.
Now you know what;
Processors are supported
Ram Memory is supported
Graphics are supported
