Shell Hardware Detection service severely slowing bootups and restarts

I recently started having problems with my Inspiron 9200 booting and shutting down VERY slowly.  It would hang once it reached the blue Windows welcome screen.  After a minute, it would reach the desktop background image and hang for another 3-5 minutes.  One shutdown, it seemed like the computer wouldn't even notice I told it to shut off but after 5 minutes it would shut down.

 

I talked to several hardware people on the Dell chat and they helped me isolate the problem but could find a way to fix it except to shut it off.  The problem is the service in msconfig called Shell Hardware Detection by Microsoft.  It controls the autoplay function of the PC.  I currently have the service disabled.  I have to enable it to use my external flash drive and DVD drive.

 

I would like to know if there is a way I can fix this service where I can use it.  I can't reinstall Windows because Dell shipped the wrong disc with my PC.  I have Windows Professional and was shipped Windows Home.  My only other alternative is to use Dell's backup to restore to factory settings.

 

Please help me, and thanks in advance.
