I've been having a problem with ridiculous CPU usage. It's been happening for ages, and I'm finally fed up with it. The draw makes the fan go crazy, so I can hear my computer from two rooms away. Oy!
I've narrowed the problem down to svchost.exe (NetworkService) PID 1092 with CPUs regularly over 50. The usage within the process comes from one of 6 services that are also labeled 1092. LanmanWorkstation is a big offender. There's also MsMpSvc, NlaSvc, dnscache and Cryptsvc. Telephony and remote desktop, don't seem to do much.
I'm not sure if this is weird or not, but there aren't any svchost entries in the process or application tabs of my Task Manager. But the 1092 entries are running in the services tab.
Here's what I have done
I have suspended the Network Service svchost. The CPU dropped quickly to less than 5%, but I couldn't open some programs or surf the web.
I flushed the DNS using ipconfig /flushDNS. It helped for 5 minutes or so, but it's back.
There are times when the computer is quiet, but it revs up for no reason, for example in the middle of the night or while I'm watching TV and haven't opened any new programs or windows.
Also, I had been blaming this problem on Firefox, but it happens when Windows Live Mail and Firefox are closed.
I have a few other issues that have popped up recently, but I don't t think they aren't related.
Oh, it might not matter, but my internet is now running through Network 14, from moving and switching plans a few times.
Thanks so much for your help in advance. Kindly let me know if there's any more information that I can provide.
P.S. I'm attaching a screen shot of the CPU usage graph. CPU.jpg 218.06KB 0 downloads Hope that works.
