No Sound Error 800703E6

Since I installed Windows Vista SP2, I lost all audio drivers and software, when I tried use Windows Update I received error 800703E6. I have tried to uninstall and reinstall Realtek High Definition Audio Drivers and software, didnt help. I receive the error "Invalid Access to memory location" Realtek High Definition Audio Device Driver.

I have also uninstalled and reinstalled SP2 with no luck...

I just went to add hardware, selected sound, video, and game controllers, I picked Realtek
as manufacturer. It started to install the software, then I received the same error " Invalid Access to Memory Location"

Can you help please..
Thank You

When doing a system restore you won't lose any documents etc, but you would have to reinstall any software you have downloaded sinse the restore.

Go back 3 to 5 days before the problem started and you should be fine.
