I am having a problem with Windows 7. When I boot up, the CPU jumps to 100% execution for about 10-15 minutes. During this time, it is really slow, and if I play any music, the songs play slowly and sound distorted.
I tried to scan my computer with different antivirus programs, I used Spybot, HijackThis, and CCleaner, but I didn’t find anything of note.
I watched the process list in Task Manager and saw that there are two processes that are to blame. There are two copies of svchost.exe
, one using ~48% CPU, the second (under the Network Service account) using ~37%. For the first 15 minutes, the CPU runs at about 70-80%, then eventually drops to 30-40%.
I don’t know what to do. I could not find a way to stop the services, and if I try to kill them, sometimes the system crashes.

You are on the right track with your investigation. The problem is that you got stuck at
svchost.exe
. The catch is thatsvchost
is a generic process that hosts multiple services. What you need to do is to figure out which service that it is hosting is sucking cycles.CPU
andCPU History
are selectedsvchost.exe
with high CPU usage,svchost
to see if it has gone down
