ok that was almost too easy, your bios id string just gave away what that motherboard really is its a msi RD480 Neo2
Evesham Vale PC oem number is MS-7194.
now double cross that at msi and you get this board.

which going by the spec has one thing of interest listed.
down in the spec sheet it say's Audio
• Azalia link controller integrated in ULi® M1573 chipset
• 8-channel audio codec Realtek ALC880
- Compliance with HD Audio (Azalia) 1.0 spec
which means the HD audio controller is built in the southbridge but its using a realtek HD chip on the end of that pci lane.
a double check with msi show's no drivers listed for vista or windows 7 other then update drivers for the realtek sound
that would mean everything is built in to the O/S and it should run out the box drivers and install on its sata with no extra input.
i see on the report your still on xp at the moment but just out of interest i want to find out what sound card drivers are installed and see which ones windows are using.
if you click start , control panel, sounds and audio devices.
click the audio tab.
just see what is listed as default playback device.
I can't really see there being a problem with windows 7 other then the low memory and your using onboard video.
windows 7 just like vista is a pretty heavy o/s to run so it likes a good amount of memory and a good gpu.
it will install on the system you have now with no updates to your memory or video cards done but it will run like a pig
if you can update your memory to 2 gig and plug in a pci express video card.
your motherboard support 4gig memory max
if your not a game player but want all the windows 7 effects without a massive pricec tag get the nvidia 9600gt.
they are cheap to buy now even brand new on ebay and they don't draw too much power.
