Something else is utilizing that cpu I would think. If it were me I would do a thorough sweep for virus's and spyware. SpySweeper and Spyware Doctor are the two best out there. I've been using SpySweeper for a few years now and highly reccomend it. At $29.95, it's a bargain. Much better than the free ones. I like free Avast for virus problems. You could also follow the anti-spyware directions on this website. First I would run CleanUp to get rid of junk files:http://www.stevengou...ftware/cleanup/
You might want to shut down utilities in the lower right corner when copying. Right click on an icon and select shutdown. If it's taking that long I would shut down the anti-virus program and anti-spyware program. If your running any Norton or McAfee program, that could be your problem. I usually recomend getting rid of Noron and McAfee programs.
When's the last time you ran the Defragmentor?
You might want to run MSCONFIG to prevent certain programs from starting up:
start>run> type 'msconfig'>startup
by unchecking something it won't start the next time you boot up. I usually keep anti-virus, anti-spyware, ups related stuff. But stuff like quicktime and update manager for Adobe can be unchecked. If your not sure what something is, do a search on google for it or post it here and we'll tell you if you can uncheck it.
How much RAM do you have? What size CPU?
