How have you reached the determination that your CPU is clocking at 100%?
You likely have an unwanted visitor running amok on your HD.
Try running Ad-aware, a Spyware scanner, just might pick up a pest or two.
Direct download here:

Install , reboot, read FAQ and overview, use online update feature to obtain
the latest
reference files, scan for Spyware much like you would with your
pre-installed anti-virus scanner.
Run Ad-aware and SpyBot on a regular basis, again like you would you A-V
scanner.
Rid your machine of unwanted Spyware pests.
