I have a client, who opens IE and gets to the company intranet. Sometimes the page will load up halfway then stop loading, everything in the picture windows locked up but you can still use the close button, enter a new website (it won't go to the new website). If you press the back button IE dissappears. If you press CTRL alt delete, IE is still running using about 45% of the cpu. It works ok in safemode, I've msconfiged all services and programs from starting up that didn't work. I tried updating to IE7 that had the same problem. I deleted the userprofile and recreated but that did not work. At the same time the machine takes literally 4 minutes to login to domain, once entering a username and password it will sit with the login box greyed out for 2-3 minutes, then go to appying settings for another 2-3 minutes.
