Thanks Ara, but I don't see any relationship between the problem and hard disk activity. The problem grows and grows depending on Web traffic. Eventually, the noise is very bad when I do anything Web related, as the tests with the DPC latency tool show
- the problem temporarily disappears when I disable the network adapter.
Nonetheless, thanks for reading my post!!
