Vista - Popping sound Vista x64

Hi.

I have a problem with the audio in Windows Vista x64,, which brings me mad.

The motherboard is a Gigabyte X58 UD5 with sound chip Realtek ALC889A.

Just start the computer everything works perfectly, but about 4 hours we start to hear noise in any audio playback (mp3, games, videos ...).

The odd thing is that if blocking network traffic problem disappears, as if you restart the computer (in this case go away for 3-4 hours)

I think it should not be hardware problem, because in windows xp everything works perfectly.

I've already more than a week trying to find a solution in forums but no way: S

Any idea? Thank you and sorry for the bad english:$

What are some of the things you have tried to fix it?

We can then make alternative suggestions

Hi.

It is already solved. It was a problem of a bad management of the interruptions on last versions of Comodo Internet Security.
I uninstall it and audio workd properly.
