While sitting idle with no programs running my cpu usage
jumps from 0 to 40% or anywhere in between every few
seconds. I have shut down any background programs I can
think of.
What can be causing this?
 
Download Ad-aware SE and scan your PC for the presence of spyware:

Enter Ctrl/Alt/Delete simultaneously and look at the Processes and
Application tabs. You can see there what is running and if you don't
recognise it then post back here. You can also end the process (hopefully)
there too. You might have malware/spyware in which case download and run
Adaware SE, Spybot Search & Destroy, CWShredder and hopefully you also have
an anti-virus application to run in addition.
 
My Netgear wireless PCMCIA card will make a CPU spike of
15% every 10 seconds or so. Take out the Netgear and it
goes away. I do not have this phenomena while connected
through a wired nic card.

I wrote Netgear, you can imagine what a waste of time
that was.

I have now tried search and destroy, disabling processes,
ad-aware, and I always keep my virus protection up to
date. Also went to the security check site as advised
but to no avail.
I am also connected to a linksys router. My other
comptuters don't have this problem. Still getting the
same pcu spikes on this one.
