100% cpu usage

Every week around the same time my cpu starts running at
100%

When the proplem occurs, CPU usages snaps up to 100
percent, and according to task mgr 'system' is using 98
to
99 percent of it, with 4 files running. The problem
requires approx 24 hours of uptime (during which CPU
continues to run at 100%) to resolve itself. Rebooting
has
no impact on the problem. It still seems to require 24
hrs
of 'thinking time' to get back to normal.

When the CPU is at 100%, the fan is going continuously
and
no other apps can be run...renduring the system totally
useless for 24 hours or more. (The recovery time has
gradually increased over time...when the prob first
occurred it took only a few hrs).

Episodes like this have occurred under any variety of
circumstances, including just sitting there, unused!

I have scanned for viruses and spyware and it comes back
clean.

I dont know what to do.
 
Try turning off ssdp and see if it stops the problem. I had a similar
issue with growth of system which has not reappeared after disabling the
ssdp service.
 
I have similar problem, now almost always after being
idle for a while system goes crazy and eats up all free
cpu resources, up to 98% and cpu usage goes to 100%. I
have not tried to let it run itself to death like seems
to work for Stuart, maybe I'll try it, but I don't like
the idea of running the computer at 100% for well over
24hrs.

I had a feeling this problem was related to msn
messenger, firewall, index-service, internet info
service, but problem remains after these have been turned
off. (not yet completely removed, if possible).
No viruses seem to be in the system, and it is very
stable if slow.

What is this ssdp service and how do I turn it off?

Thanks

The ssdp service is one of the services that supports UPnP. To disable
it go start/control panel/administrative tools/services double click on
the SSDP discovery service entry, select stop, and then select disable
from the startup type menu.
