H2Fix this problem?

OK . I know I screwed this up and I just need some help.

Computer is a new Dell Inspiron 5100 loaded with Windows XP, Norton System Works.

I loaded SpyBot and Kerios Personal Firewall. and it seemed to be fine.

Now it is locked up with a black screen and won't respond to any input from me. This includes the on off button.

Help.

I think I either removed some key files/drivers or these two nprograms are locked in mortal combat.

What should I do?

 

If you can get to Safemode, use System Restore to go back to a time prior to installing Spybot and Kerio...
