I am a guest at a friends house and her mom's installed SP2 on Toshiba 1115-S103 running XP Home Build 2600. They also installed black ice defender and Norton Antivirus. The computer stalled with e-mail(outlook express) and other programs would hang. I hit system restore and when I got back 20 minutes later the screen was black. I rebooted in all modes(normal, safe, last known config) and the system goes through the Win XP loading screen then freezes on black screen. I really need to get out of this pickle. I've used system restore but avoided SP 2 for a reason. Please, please help, they are waiting.
