I am facing a very rare problem and it's causing much trouble. Whenever I boot my PC(HP 2000-2116tu, Win7, 4GB mem), there is a set of processes(legitimate ones and not virus), one of which starts to consume CPU and takes usage level to 40%. When I open the Resource Monitor, and right click on the process to analyze wait chain, this message is displayed- One or more threads are waiting to finish network i/o. If I end this process, then some other process takes over and exhibits the same behavior. Note that only one process at a time does so.This keeps on untill I end each of them one by one, but it is not a solution because I need those process as well.

My CPU gets heat up very much because of this excessive usage and the vents feel to be burning.

The Processes are: DCSHelper.exe(data Card Monitor), Firefox.exe(Mozilla Firefox), PhotonPlus.exe(Mobile Internet Data Card Process), Nclmbtr.exe(Microsoft Bluetooth Server), jusched.exe(Java Update Scheduler), and many more similar ones.

One common thing I noticed about these processes is that all these interact with external Devices/interfaces/network. I use Microsoft Security Essentials and have run a full scan but no good it did. Please help if someone is aware of such an issue.

This question came from our site for system and network administrators.

Do you use any other firewall, anti-virus or anti-malware programs (including browser add ons). – David Schwartz Mar 20 '13 at 11:21
MSCONFIG - disable all the programs you don't want to start up (this may include this process)! Then add them one at a time to find the faulty process (or manually kill them in task manager one at a time which is less hassle than a reboot!) – Dave Mar 20 '13 at 12:47
