What does this mean!? Help please!!

I’m having some virus trouble and since then I have no sound. I have a Creative Soundblaster Audigy 24 bit Soundcard installed.

Control Panel Says: "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)"

The viruses load up on boot, ending the viruses on task manager stops a blue screen error, but the viruses won’t be detected by my anti-virus.

I tried to do system restore, to a point 2 days ago, when the sound worked and I keep getting blue screen errors saying your computer has been shut down to prevent hardware damage.
I can’t start my computer in safe mode either, and last known good configuration gets the same blue screen error.
I also have "Registry Mechanic" back-ups for my registry for various dates, but this fails to solve the problem too.

I try and play a file in winamp and get the following error with a loud beep:
Nullsoft Direct sound output v.2.47 (d) error. Bad directsound driver, please install proper drivers or select another device in configaration.
Error code: 88780078

Direct x says: "No sound card was found. If one is expected, you should install a sound driver provided by the hardware manufacturer."

Please can you link me the drivers for my Soundcard or provide any other help for restoring the registry.

"do you have sytem restore"
I have one for 30 October 2008 (made by Registry Mechanic) so there will be a back up of my registry. But I get a blue screen hardware error.

I also tried this: http://www.downloadatoz.com/windows-registry/faq,how-to-repair-windows-code-19-registry.html

However, Registry Booter would not install due to this error: http://support.microsoft.com/kb/315353
