Yeah, hey...welcome to the forums here.
Two things should get you straightened out there.
1) Boot to safe mode + networking. The visit this thread and download, install and run Driver Sweeper in my link here:
Phyxion.net | Driver Sweeper | Products | Products
Use it to clean all the Creative sound drivers and software.
Reboot and install the Creative driver package for your card fresh from here:
Creative Worldwide Support
2) When done, open an
elevated command prompt. Copy and paste this command to it with the mouse, then press enter and let it finish:
sfc /scannow
Don't even pay attention to what it says...simply reboot when it is done.
