Not ending it leaves the comp slow ofcourse. Comp worked fine before. This svchost.exe problem showed up out of nowhere and now I don't know how to stop it from using my entire cpu. Anyone have any idea? :-\ Thanx.

However, I just found the culprit process that was responsible - it was none other than DNSCACHE !
First, you need to know the Process ID (PID) of the troublesome process - this is done using good ol' Task Manager (assuming you have already enabled the PID column from 'view columns' from the "view/select columns" menu bar, whilst on the PROCESSES Tab)

Using the command "Tasklist /SVC" from CMD Prompt, I was able to match the PID of the problem SVCHOST process to object that was using it - in my case, it was DNSCACHE. What I guess was occurring was that after every start-up, when trying to connect to internet, DNSCACHE 1st wanted to update - this could take quite some time in some instances, and as I've discovered, was completely un-neccessary. The fix was to STOP the DNSCACHE service, then set it to DISABLED, all within LOCAL SERVICES. Problem is now gone, and internet access is fully functional. Hope this is of some help to others with similar problem.
