CPU USage 100%

[Ankur]

The svchost.exe is always running with 95% plus CPU
usgage all the time. After trouble shooting following
Microsoft Help and Support I found that Remote Procedure
Call (RPC) is the Service which is responsible for it.
I came to this conclusion as the Process ID number of the
svchost from the task manager is the same as the PID
number of it from command promt tasklist /svc

Please help me understand why is this service churning up
the CPU all the time and what can I do to fix this
problem.
Thanks

From an earlier post by Peter:

Try to boot in safe mode.
Go to Symantec.com to have an on-line security check to
ensure your PC is 100% virus free. Then boot in normal
mode and run anti-spyware software, such as Ad-aware 6.0
or Spybot to check for spyware. It is free for download from
lavasoftusa.com or download.com if you don't have it.
Temporarily disable the restore feature to clear all the
restore files, then reboot. Enable the restore feature
again. Rescan the whole system for virus check.
If is still no avail, perform a repair install of XP
using XP CD (this should be done provided that you are
100% sure that the PC is clean from viruses).
Be careful if you only have the recovery CD, it will wipe
out all the data files.
