svchost.exe takes up 99% of CPU

[ac319]

For some reason when I both this computer it never fully
comes up because there ar 4 instances of svchost.exe and
one of them uses 99% of the CPU. I got in safe mode and
ran Norton and there are NO viruses on my machine.
Help. I also upgraded my windows and nothing. Same
problem. Also I get this message the the "TCP/IP netowrk
transport is not installed". I reset it and then it was
there and then dissappeared again. help

SVChost runs a whole slew of services on behalf of the system - one is
running away. Given it does not seem to be spyware of the like, you
have to find which is using the cpu and if possible do without it.

At Control Panel - Admin Tools - Services selectively stop likely
services to see which one is causing the load (start them again if
stopping has no effect). The likely candidates are

Background Intelligent Transfer (needed by Automatic Updates, but you
can do manual ones with it off)

Routing and Remote access - which you probably would not miss -

or the pair
SSDP Discovery service and
Universal Plug and Play
- if you stop one, stop both. Those are only important if you use a
router that needs UPnP to handle Net Address Translation
