100% CPU Usage

Ok, my explorer.exe is using 100% of my cpu about 1 minute after I boot my computer.  Ive tried scanning with Spybot but no luck.  Right now my temp fix is to stop explorer and then start it again as a new task. 

Any advice would be appreciated.

explorer isn't internet explorer....
are you sure that's explorer? you should check other processus, and check your win.ini to see what's loading at startup
also check your regiter.
