Here is a screen shot of the "Safe Mode". You get to "Safe Mode" by tapping the F8 key while booting. It sounded like, from your eailer description, the SB tech had you attempt the "Last Known Good Configuration" utility. If it works, it will restore XP to a point before you removed any programs. If it was already tried and / or did not work, then reinstalling XP may be your only option.
