My humble advice to you would be to either upgrade your Rig to make use of Windows 7 or rather use Windows XP as it has all the drivers
you need to get the system working properly.
Trying to install drivers from unknown sources apart from Manufacturer of your motherboard or Sound card chip manufacturer is seriously not something you should do or recomended.
You will eventually end up getting BSOD's ...The choice is yours ....
PS: the point is you may or maynot get it to work eventually under win 7 and loosing your hair due to issue that arise after that is your call !!!
