Intel 82801GBM ICH7-M - High Definition Audio Controller

 

I did some research and your PC is actually made by ECS/Uniwill and is a model #L51II (those are two upper case "i"). Here's the drivers for both XP and Vista.

I also found this Intel/Realtek driver for audio that may work too:

You may also need the Intel/MS UAA audio driver (the two links look the same, but they go to slightly different downloads)-
