Hi voltron,
You might try disabling the SSDP Discovery Service and see if this helps at all. To do this, go to Start -> Run and type 'services.msc' (without the quotation marks). Scroll down until you get to 'SSDP Discovery Service' and double click on it. Under 'Service status' click the 'Stop' button and then change 'Startup type' to 'Disabled'. Click Apply, Ok and then reboot the computer.
It may not make a difference, but it's worth a try
