VIA sound card issue

Hello

I have an Asus G75 gaming laptop here, an old knockaround, and I have a vexing problem. I cannot launch a game (World of Warcraft) in 64 bit mode, but it launches fine in 32 bit. With the help of some others the problem was narrowed down to the sound card/driver which is a VIA sound card.

If I disable the sound card the game launches fine in 64bit. The same can be said if I uninstall the drivers.

This is the message that greets me when I try to launch the game in 64 bit (I have attached it as well):

Okay, I was told it could be a memory conflict or a driver conflict. Anyone have any ideas how I would go about fixing this?

My approach would be to see if the sound card will work with the generic WIN OS, let it find the driver needed.  You may find the fault in the registry but that's for the pros to mess with.  I have seen some install programs that come with a plugin card overwrite interrupts and make registry changes.  Possibly a restore back to before the fault occurred and a registry examination might reveal the  changes.

I did try using the default windows driver. I uninstalled everything (the game launched in 64 bit), then I installed the windows driver and no dice. Do you have any good recommendations for methods or software that could scan my registry for errors. I know I can look that up, but to have a recommendation from an unbiased source would be good.

Thank you for the response.
