The second one sounds like one of the services is either being kept busy or is failing to stop. I'd look at a mass driver update, especially networking and chipset (motherboard) related. There may not be newer drivers available but sometimes even a reinstall of the same drivers can clear that kind of issue up, if one of the driver files has become slightly corrupt.
The first issue I haven't come across before, which rule type are you using (sender based or content based?).
