When the process is running check you Task Manager to see what is using up your resources.

When in the task manager end process on one task at a time, if it restarts and is not a regular windows service then chances are that's your problem app. I've found it easier to sort by name before end a process so thta I can easily identify it if it restarts.

If you are unable to tell but have narrowed it down to something tied to IE, the uninstall and applications that you are unsure about and reinstall IE.
If you are unable to find any kind of trojan virus that I would suggest that you remove IE7 if that is the version that you have in your pc. An it will roll back auto. to IE6. If you don't have IE7 and IE6 just to to add/remove and after reinstall the program.
