FDResPub service eats CPU resources
I have an irritating problem with my Windows 7 32-bit, I've searched the internet and while I found some similar problems and solutions to them they didn't help me.
A month ago I upgraded my motherboard from Gigabyte GA-M61SME-S2 to Asrock N68C-GS FX and the processor from Athlon 64 4000+ 2.1 GHz to Athlon X2 270 3.4 GHz. After a few system restarts and installing new drivers I was able to get back my OS installation working fine. There's only one problem I experience - occasionally, an svchost.exe service gets "turned on" for some reason and begins constantly using my CPU at about 33% and will not stop on its own. The svchost.exe process points to FDResPub service (Function Discovery Resource Publication). The service startup type is set to Manual. When I stop the service the CPU usage continues but now it is transferred to another service called SSDPSRV (SSDP Discovery). When I stop this service then finally the CPU usage goes down to zero.
I know this has something to do with networking but I don't want to disable any services in case they may be important. I'm using onboard LAN and I'm connected to the internet via a PPoE connection. I've noticed that if I make any change in any of my network adapter settings then the CPU usage drops to zero but later the problem comes back again. For example, there is VirtualBox Host-Only Ethernet Adapter, someone suggested that this can be the source of the problem so I turned off the "Virtual Bridged Networking Driver" but it only helped once and the problem still comes back. Also, I have another ethernet network cart (Realtek) and I thought it could be the cause so I disabled it completely and again this helped only once and the problem comes back.
The annoying thing is that it's difficult to troubleshoot because the problem comes back at random and I'm not able to reproduce it on demand. For example, I am looking over some code in Netbeans and out of the blue I begin to notice higher CPU usage. Often when I leave my computer running and come back after a few hours I notice the FDResPub service consuming my CPU resources and power for nothing.
Does anyone have an idea what can be wrong? I'm considering disabling FDResPub completely but I'd like to avoid it if possible.
