My son is away at school and is SO bad at computers and software, and I am not much better.He recently updated XP Pro because he was prompted to do so. I think it was Service Pack 2 as he said it took 20 minutes to do on a broadband connection, which he had just installed. The system went berserk and got stuck on a blue screen. I got him to get into safe mode and he was installing the last best configuration (I can never remember the exact term) of XP. His roommate tripped over the outlet as he was half done, and now he's back to square one, but now he says he can't get to the part where the computer prompts him to go to the last best configuration. He does not have his original XP Pro disc. Any suggestions?
