790 corruption issues?

[pinto]

After using P05 on my EVGA 790i, the system seems much, much more stable.

I do have a question, when I run sfc /scannow, it still says I have corruption - I assume that this means I should reinstall Vista?
Also, is anyone experiencing issues with using an X-Fi on an EVGA 790i? I get a ton of crackling and distortion, especially when loading something.

issue with forceware 175.16 but not with old 174.74 specially when i use SLI.
