For future reference, never delete a program. Uninstall it. otherwise alot of settings remain in the registry. Especially where antivirus software, especially norton, is concerned, it's even more critical. It's very possible to have bits of Mcafee running as well as norton. I know first hand that norton processes might continue running even when uninstalled.

Try enabling bootlogging by tapping F8 as soon as you start the computer. That will take you to an advanced startup menu, choose bootlog. after you've booted, check your root directory for bootlog.txt - open it with notepad.
